This will make it easier to do various clever things that don't depend
on the pure tree contents. It also makes the parameter passing much
simpler - the callers doesn't really look at trees anywhere else, and
it's really the function that should look at the low-level details.

We already support decorating commits by tags or branches that point to
them, but especially when we are looking at multiple branches together,
we sometimes want to see _how_ we reached a particular commit.
We can abuse the '->util' field in the commit to keep track of that as
we walk the commit lists, and get a reasonably useful view into which
branch or tag first reaches that commit.
Of course, if the commit is reachable through multiple sources (which is
common), our particular choice of "first" reachable is entirely random
and depends on the particular path we happened to follow.

Commit 9441b61dc5 introduced serious bugs in index-pack which are
described and fixed by commit ce3f6dc655. However, despite the
boldness of those bugs, the test suite still passed.
This improves t5302-pack-index.sh so to ensure a much better code
path coverage. With commit ce3f6dc655 reverted, 17 of the 26 tests
do fail now.

Since commit 9441b61dc5, two issues affected correct behavior of
index-pack:
1) The real_type of a delta object is the 'real_type' of its base, not
the 'type' which can be a "delta type". Consequence of this is a
corrupted pack index file which only needs to be recreated with a
good index-pack command ('git verify-pack' will flag those).
2) The code sequence:
result->data = patch_delta(get_base_data(base), base->obj->size,
delta_data, delta_size, &result->size);
has two issues of its own since base->obj->size should instead be
base->size as we want the size of the actual object data and not
the size of the delta object it is represented by. Except that
simply replacing base->obj->size with base->size won't make the
code more correct as the C language doesn't enforce a particular
ordering for the evaluation of needed arguments for a function call,
hence base->size could be pushed on the stack before get_base_data()
which initializes base->size is called.

There is no need to keep the base object data around after its last delta
has been resolved. This also means that long delta chains with only one
delta per base won't grow the cache size unnecessarily as the base will
be freed before recursing down.
To make it easy, find_delta_children() is modified so the first and last
indices are initialized in all cases.

Instead of having strange loops for walking unresolved deltas with the
same base duplicated in many places, let's rework the code so this is
done in a single place instead. This simplifies callers quite a bit too.

Jeff King noticed that this series uses non-portable ${var:0:7} syntax
to splice a string, which is not even in POSIX, in the script. A quick
look at around the offending part revealed a few issues, which this commit
fixes:
* Why filter output from "rev-list --left-right A...B" and look for the
ones that begin with ">"? Wouldn't "rev-list A..B" give that?
* The abbreviated SHA-1 are made with "rev-list --abbrev=7" into $TODO in
an earlier invocation, and it can be more than 7 letters to avoid
ambiguity. Not just that "${r:0:7} is not even in POSIX", but use of
it here is actively wrong.
* There is no point in catting a single file and piping it into grep.

This seems like the best guess we can make until git sequencer marks are
available. That being said, within the context of re-ordering a commit before
its parent in todo, I think applying it on top of the current commit seems like
a reasonable assumption of what the user intended.

This covers an odd boundary case found by Avi Kivity's script where a branch
coming off of UPSTREAM is merged into HEAD. Initially it show up in
UPSTREAM..HEAD, but technically UPSTREAM is not moving, the rest of head is, so
we should not need to rewrite the merge.
This adds a check saying we can keep `preserve=t` if `p=UPSTREAM`...unless this
is the first first-parent commit in our UPSTREAM..HEAD rev-list, which could
very well point to UPSTREAM, but we still need to consider it as rewritten so we
start pulling in the rest of the UPSTREAM..HEAD commits that point to it.

This is heavily based on Stephan Beyer's git sequencer rewrite of rebase-i-p.
Each commit is still found by rev-list UPSTREAM..HEAD, but a commit is only
included in todo if at least one its parents has been marked for rewriting.

If the current-commit was dumped to REWRITTEN, but then we squash the next
commit in to it, we have invalidated the HEAD was just written to REWRITTEN.

Currently git-blame outputs text from the commit messages
(e.g. the author name and the summary string) as-is, without
even providing any information about the encoding used for
the data. It makes interpreting the data in multilingual
environment very difficult.
This commit changes the blame implementation to recode the
messages using the rules used by other commands like git-log.
Namely, the target encoding can be specified through the
i18n.commitEncoding or i18n.logOutputEncoding options, or
directly on the command line using the --encoding parameter.
Converting the encoding before output seems to be more
friendly to the porcelain tools than simply providing the
value of the encoding header, and does not require changing
the output format.
If anybody needs the old behavior, it is possible to
achieve it by specifying --encoding=none.

If any of the filename contains two consecutive dots, it's kept as a CGI
parameter since the resulting path would otherwise be ambiguous.

This patch enables gitweb to parse URLs with more information embedded
in PATH_INFO, reducing the need for CGI parameters. The typical gitweb
path is now $project/$action/$hash_base:$file_name or
$project/$action/$hash
This is mostly backwards compatible with the old-style gitweb paths,
$project/$branch[:$filename], except when it was used to access a branch
whose name matches a gitweb action.

We used to have non-POSIX comformant BRE in our code, and linked with GNU
regexp library on a few platforms (Darwin, FreeBSD and AIX) to work it
around. This was backwards.
We've fixed the broken regexps to use ERE that native regexp libraries on
these platforms can handle just fine. There is no need to link with GNU
regexp library on these platforms anymore.

The current behavior of git-daemon is to simply close the connection on
any error condition. This leaves the client without any information as
to the cause of the failed fetch/push/etc.
This patch allows get_remote_heads to accept a line prefixed with "ERR"
that it can display to the user in an informative fashion. Once clients
can understand this ERR line, git-daemon can be made to properly report
"repository not found", "permission denied", or other errors.
Example
S: ERR No matching repository.
C: fatal: remote error: No matching repository.

Occasionally, it may be useful to prevent branches from getting deleted from
a centralized repository, particularly when no administrative access to the
server is available to undo it via reflog. It also makes
receive.denyNonFastForwards more useful if it is used for access control
since it prevents force-updating by deleting and re-creating a ref.

Gmail is one of the most popular email providers in the world. Now that Gmail
supports IMAP, sending properly formatted patches via `git imap-send` is
trivial. This section in SubmittingPatches explains how to do so.

This makes attributes easier to find; before this patch some
attributes had individual subsections, and some didn't.

Since no version of receive-pack accepts these "funny refs", we should
mirror the check when considering the list of refs to send. IOW, don't
even make them eligible for matching or mirroring.

The comments for normalize_absolute_path explicitly claim
that the source and destination buffers may be the same
(though they may not otherwise overlap). Thus the call to
memcpy may involve copying overlapping data, and memmove
should be used instead.
This fixes a valgrind error in t1504.

In the main loop of find_deltas, we do:
struct object_entry *entry = *list++;
...
if (!*list_size)
...
break
Because we look at and increment *list _before_ the check of
list_size, in the very last iteration of the loop we will
look at uninitialized data, and increment the pointer beyond
one past the end of the allocated space. Since we don't
actually do anything with the data until after the check,
this is not a problem in practice.
But since it technically violates the C standard, and
because it provokes a spurious valgrind warning, let's just
move the initialization of entry to a safe place.
This fixes valgrind errors in t5300, t5301, t5302, t303, and
t9400.

Most cache_entry structs are allocated by using the
cache_entry_size macro, which rounds the size of the struct
up to the nearest multiple of 8 bytes (presumably to avoid
memory fragmentation).
There is one exception: the special "conflict entry" is
allocated with an empty name, and so is explicitly given
just one extra byte to hold the NUL.
However, later code doesn't realize that this particular
struct has been allocated differently, and happily tries
reading and copying it based on the ce_size macro, which
assumes the 8-byte alignment.
This can lead to reading uninitalized data, though since
that data is simply padding, there shouldn't be any problem
as a result. Still, it makes sense to hold the padding
assumption so as not to surprise later maintainers.
This fixes valgrind errors in t1005, t3030, t4002, and
t4114.
