We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.

nmtst_get_rand_int() was originally named that way, because it
calls g_rand_int(). But I think if a function returns an uint32, it
should also be named that way.
Rename.

These tests cannot (easily) be under "shared/nm-libnm-core-aux/tests"
because libnm/libnm-core requires code under shared while
"nm-libnm-core-aux" requires libnm/libnm-core. With autotools that is
not problem, but with meson we include sub directories in a particular
order and there is no way to foward declare stuff (AFAIK). To avoid
the circular dependency, add the tests to "clients/common/tests", which
is always built last.

From the files under "shared/nm-utils" we build an internal library
that provides glib-based helper utilities.
Move the files of that basic library to a new subdirectory
"shared/nm-glib-aux" and rename the helper library "libnm-core-base.la"
to "libnm-glib-aux.la".
Reasons:
- the name "utils" is overused in our code-base. Everything's an
"utils". Give this thing a more distinct name.
- there were additional files under "shared/nm-utils", which are not
part of this internal library "libnm-utils-base.la". All the files
that are part of this library should be together in the same
directory, but files that are not, should not be there.
- the new name should better convey what this library is and what is isn't:
it's a set of utilities and helper functions that extend glib with
funcitonality that we commonly need.
There are still some files left under "shared/nm-utils". They have less
a unifying propose to be in their own directory, so I leave them there
for now. But at least they are separate from "shared/nm-glib-aux",
which has a very clear purpose.

We built (among others) two libraries from the sources in "shared/nm-utils":
"libnm-utils-base.la" and "libnm-utils-udev.la".
It's confusing. Instead use directories so there is a direct
correspondence between these internal libraries and the source files.

"shared/nm-utils" contains general purpose utility functions that only
depend on glib (and extend glib with some helper functions).
We will also add code that does not use glib, hence it would be good
if the part of "shared/nm-utils" that does not depend on glib, could be
used by these future projects.
Also, we use the term "utils" everywhere. While that covers the purpose
and content well, having everything called "nm-something-utils" is not
great. Instead, call this "nm-std-aux", inspired by "c-util/c-stdaux".

... and the "unescape" variants.
This is replaced by nm_utils_escaped_tokens_split()
and nm_utils_escaped_tokens_escape*() API.

This can be replaced by nm_utils_escaped_tokens_split().
Note that nm_utils_escaped_tokens_split() does not behave exactly
the same. For example, nm_utils_str_simpletokens_extract_next() would
remove all backslashes and leave only the following character.
nm_utils_escaped_tokens_split() instead only strips backslashes
that preceed a delimiter, whitespace or another backslash.
But we should have one preferred way of tokenizing, and I find this
preferable, because it allows for most backslashes to appear verbatim.

This escapes strings so that they can be concatenated with a delimiter
and without loss tokenized with nm_utils_escaped_tokens_split().
Note that this is similar to _nm_utils_escape_plain() and
_nm_utils_escape_spaces(). The difference is that
nm_utils_escaped_tokens_escape() also escapes the last trailing
whitespace. That means, if delimiters contains all NM_ASCII_SPACES, then
it is identical to _nm_utils_escape_spaces(). Otherwise, the trailing
space is treated specially. That is, because
nm_utils_escaped_tokens_split() uses NM_UTILS_STRSPLIT_SET_FLAGS_STRSTRIP,
to strip leading and trailing whitespace. To still express a trailing
whitespace, the last whitespace must be escaped. Note that
NM_UTILS_STRSPLIT_SET_FLAGS_STRSTRIP also honors escaping any whitespace
(not only at the last position), but when escaping we don't need to
escape them, because unescaped (non-trailing) whitespace are taken just
fine.
The pair nm_utils_escaped_tokens_split() and
nm_utils_escaped_tokens_escape() are proposed as default way of
tokenizing a list of items. For example, with
$ nmcli connection modify "$PROFILE" +ipv4.routing-rules 'priority 5 from 192.168.7.5/32 table 5, priority 6 iif a\, from 192.168.7.5/32 table 6'
Here we implement a to/from string function to handle one item
(nm_ip_routing_rule_{from,to}_string()). When such elements are combined with ',',
then we need to support an additional layer of escaping on top of that.
The advantage is that the indvidual to/from string functions are agnostic
to this second layer of escaping/tokenizing that nmcli employs to handle
a list of these items.
The disadvantage is that we possibly get multiple layers of backslash
escapings. That is only mitigated by the fact that nm_utils_escaped_tokens_*()
supports a syntax for which *most* characters don't need any special escaping.
Only delimiters, backslash, and the trailing space needs escaping, and
these are cases are expected to be few.

Add a new flag that will remove escape characters after splitting
the string.
This implements a special kind of backslash escaping. It's not C escape
sequences (like '\n' or '\020'), but simply to take the special character
following the backslash verbatim. Note that the backslash is only
considered special, if it's followed by a delimiter, another backslash,
or a whitespace (in combination with %NM_UTILS_STRSPLIT_SET_FLAGS_STRSTRIP).
The main purpose of this form of escaping is nmcli's list options, like
$ nmcli connection modify "$PROFILE" +ipv4.routing-rules 'priority 5 from 192.168.7.5/32 table 5, priority 6 iif a\, from 192.168.7.5/32 table 6'
It's a contrieved example, but the list options are a list of IP
addresses, rules, etc. They implement their own syntax for one element,
and are concatenated by ','. To support that one element may have
arbitrary characters (including the delimiter and whitespaces), nmcli
employs a tokenization with this special kind of escaping.

This will essentially call g_strstrip() on each token.
There are some specialties:
- if the resulting word is empty after stripping, then according to
%NM_UTILS_STRSPLIT_SET_FLAGS_PRESERVE_EMPTY, the empty token will be
removed. If that results in an empty string array, %NULL will be
returned.
- if %NM_UTILS_STRSPLIT_SET_FLAGS_ALLOW_ESCAPING is set, then
whitespace that is backslash escaped is not removed.
Since this is a post-operation that happens after tokeninzing, it
could be done as a separate function. And we already have this function:
_nm_utils_unescape_plain() and _nm_utils_unescape_spaces().
However, that is ugly for several reasons:
- the stripping should be part of the tokenizing, you shouldn't need
several steps.
- nm_utils_strsplit_set_full() returns a "const char **" which
indicates the strings must not be freed. However, it is perfectly
valid to modify the string inplace. Hence, the post-op function
would need to cast the strings to "char *", which seems ugly
(although we do that on many places, and it's guaranteed to work).
- _nm_utils_unescape_plain()/_nm_utils_unescape_spaces() is indeed
already used together with nm_utils_strsplit_set_full(). However,
it requires to initialize the cb_lookup buffer twice. I would expect
that initializing the cb_lookup buffer is a large portion of what
the function does already (for short strings).
This issue will be solved in the next commit by adding yet another flag
which allows to unescape.

This removes libnm-glib, libnm-glib-vpn, and libnm-util for good.
The it has been replaced with libnm since NetworkManager 1.0, disabled
by default since 1.12 and no up-to-date distributions ship it for years
now.
Removing the libraries allows us to:
* Remove the horrible hacks that were in place to deal with accidental use
of both the new and old library in a single process.
* Relief the translators of maintenance burden of similar yet different
strings.
* Get rid of known bad code without chances of ever getting fixed
(libnm-glib/nm-object.c and libnm-glib/nm-object-cache.c)
* Generally lower the footprint of the releases and our workspace
If there are some really really legacy users; they can just build
libnm-glib and friends from the NetworkManager-1.16 distribution. The
D-Bus API is stable and old libnm-glib will keep working forever.

Instead of growing the buffer for the tokens (and reallocating),
do one pre-run over the string and count the delimiters. This
way we know how much space we need and we don't need to
reallocate.
Interestingly, this is notably slower than the previous implementation,
because previously if would not bother determining the right number of
tokens but just over-allocate with a reasonable guess of 8 and grow the
buffer exponentially. Still, I like this better because while it may
be slower in common scenarios, it allocates the exact number of buffer
space.

nm_utils_strsplit_set_full()
Previously, nm_utils_strsplit_set_full() would always remove empty
tokens. Add a flag NM_UTILS_STRSPLIT_SET_FLAGS_PRESERVE_EMPTY to avoid
that.
This makes nm_utils_strsplit_set_full() return the same result as
g_strsplit_set() and a direct replacement for it -- except for "",
where we return %NULL.

Drop the next_char() and is_delimiter() macros. They are difficult to
understand, because they both have a state-variable (escaped).
Instead, the state of whether we handle an escape or not, shall only
depend on the current line of code.

The caller should make a conscious decision which delimiters to use.
Unfortunately, there is a variety of different demiters in use. This
should be unitfied and the callers should use one of a few specific
set of delimiters.
This could be unified by (re)using a define as delimiters, like
strv = nm_utils_strsplit_set_full (value, MULTILIST_WITH_ESCAPE_CHARS, NM_UTILS_STRSPLIT_SET_FLAGS_ALLOW_ESCAPING);
where MULTILIST_WITH_ESCAPE_CHARS has a particular meaning that should
be reused for similar uses.
However, leaving the delimiter at NULL is not good because it's unclear who
wants that default behavior (and what the default should be). Don't allow that.
There are almost no callers that relied on this default anyway.

It will be useful to extend nm_utils_strsplit_set() with various
flavors and subtly different behaviors. Add a flags argument to
support these.

Previously, this would re-implement what nm_strstrip_avoid_copy()
was doing.
Use nm_strstrip_avoid_copy_a() instead, which avoids the code
duplication and the heap allocation in common cases.

"nm-macros-internal.h"
The main difference between "shared/nm-utils/nm-macros-internal.h" and
"shared/nm-utils/nm-shared-utils.h" is that the former is header-only
while the latter has a source file as well.
Apart from that, both headers are included everywhere.
The next commit will add nm_strstrip_avoid_copy_a() to
"nm-macros-internal.h" header, which will use nm_strndup_a().
Hence, also nm_strndup_a() should be in "nm-macros-internal.h".

nm_str_skip_leading_spaces() macros
"_str" is a very tempting name for a temporary variable.
Rename the variable in nm_strndup_a() macro, so that other macros can
call these (more general) macros (and still use the name "_str").

If we don't have explicit_bzero(), try a bit harder and use
a volatile pointer.
This is also what libsecret's egg_secure_clear() does [1]. However, for
us this is less important, because commonly we expect glibc to provide
a useable explicit_bzero().
[1] https://gitlab.gnome.org/GNOME/libsecret/blob/b5442654d483e959ac9ecd3a3fb9eebc8d9d8399/egg/egg-secure-memory.c#L1352

It's usually not necessary, because _nm_utils_unescape_spaces()
gets called after nm_utils_strsplit_set(), which already removes
the non-escaped spaces.
Still, for completeness, this should be here. Also, because with
this the function is useful for individual options (not delimiter
separate list values), to support automatically dropping leading or
trailing whitespace, but also support escaping them.

nm_utils_parse_inaddr_bin()
nm_utils_parse_inaddr() is trivial enough to reimplement it, instead of calling
nm_utils_parse_inaddr_bin(). Calling nm_utils_parse_inaddr_bin() involves several
things that don't matter for nm_utils_parse_inaddr() -- like assigning
out_addr_family or returning the binary address.
