I've updated copyright dates in glibc for 2018.  This is the patch for
the changes not generated by scripts/update-copyrights and subsequent
build / regeneration of generated files.

Please remember to include 2018 in the dates for any new files added
in future (which means updating any existing uncommitted patches you
have that add new files to use the new copyright dates in them).

From localedef --help:

Output control:
...
      --no-warnings=<warnings>   Comma-separated list of warnings to disable;
                             supported warnings are: ascii, intcurrsym
...
      --warnings=<warnings>  Comma-separated list of warnings to enable;
                             supported warnings are: ascii, intcurrsym

Locales using SHIFT_JIS and SHIFT_JISX0213 character maps are not ASCII
compatible. In order to build locales using these character maps, and
have localedef exit with a status of 0, we add new option to localedef
to disable or enable specific warnings. The options are --no-warnings
and --warnings, to disable and enable specific warnings respectively.
The options take a comma-separated list of warning names. The warning
names are taken directly from the generated warning.  When a warning
that can be disabled is issued it will print something like this: foo is
not defined [--no-warnings=foo]

For the initial implementation we add two controllable warnings; first
'ascii' which is used by the localedata installation makefile target to
install SHIFT_JIS and SHIFT_JISX0213-using locales without error; second
'intcurrsym' which allows a program to use a non-standard international
currency symbol without triggering a warning.  The 'intcurrsym' is
useful in the future if country codes are added that are not in our
current ISO 4217 list, and the user wants to avoid the warning. Having
at least two warnings to control gives an example for how the changes
can be extended to more warnings if required in the future.

These changes allow ja_JP.SHIFT_JIS and ja_JP.SHIFT_JISX0213 to be
compiled without warnings using --no-warnings=ascii. The
localedata/Makefile $(INSTALL-SUPPORTED-LOCALES) target is adjusted to
automatically add `--no-warnings=ascii` for such charmaps, and likewise
localedata/gen-locale.sh is adjusted with similar logic.

v2: Bring verbose, be_quiet, and all warning control booleans into
record-status.c, and compile this object file to be used by locale,
iconv, and localedef. Any users include record-status.h.
v3: Fix an instance of boolean coercion in set_warning().

Recorded verbose messages no longer need to pass \n in their
message string since the record_verbose function adds \n to
the messages (like error and warnings do also). The avoids
seeing a double \n for verbose messages.

In "Is it OK to write ASCII strings directly into locale source files?"
https://sourceware.org/ml/libc-alpha/2017-07/msg00807.html there is
universal consensus that we do not have to keep writing <Uxxxx> symbolic
characters in locale files.

Ulrich Drepper's historical comment was that symbolic characters were
used for the eventuality of converting the source files to any encoding
system. Fast forward to today and UTF-8 is the standard. So the
requirement of <Uxxxx> is hard to justify.

Zack Weinberg's excellent scripts are coming along we can use these to
find instances of human errors in the scripts:
https://sourceware.org/ml/libc-alpha/2017-07/msg00860.html
https://sourceware.org/ml/libc-alpha/2017-08/msg00136.html

It still won't be easy to distinguish from i for í, but that's still the
case for <Uxxxx> characters which humans can't read either.

Since we all agreed that we should be able to use non-symbolic (<Uxxxx>)
characters in locale files, the following change removes the verbose
warning that is raised if you use non-symbolic characters in the locale
file.

The builtin POSIX locale has "" as the international currency symbol,
but a non-builtin locale may not have such a blank int_curr_symbol.

Therefore to support non-builtin locales with similar "" int_curr_symbol
we adjust the LC_MONETARY parser to allow the normal 4-character
int_curr_symbol *and* the empty "" no symbol. Anything else remains
invalid.

Tested by building all the locales.  Tested also with a custom C.UTF-8
locale with "" for int_curr_symbol.

The error and warning handling in localedef, locale, and iconv
is a bit of a mess.

We use ugly constructs like this:
      WITH_CUR_LOCALE (error (1, errno, gettext ("\
cannot read character map directory `%s'"), directory));

to issue errors, and read error_message_count directly from the
error API to detect errors. The problem with that is that the
code also uses error to print warnings, and informative messages.
All of this leads to problems where just having warnings will
produce an exit status as-if errors had been seen.

To fix this situation I have adopted the following high-level
changes:
* All errors are counted distinctly.
* All warnings are counted distinctly.
* All informative messages are not counted.
* Increasing verbosity cannot generate *more* errors, and
  it previously did for errors conditional on verbose,
  this is now fixed.
* Increasing verbosity *can* generate *more* warnings.
* Making the output quiet cannot generate *fewer* errors,
  and it previously did for errors conditional on be_quiet,
  this is now fixed.
* Each of error, warning, and informative message has it's
  own function to call defined in record-status.h, and they
  are: record_error, record_warning, and record_verbose.
* The record_error function always records an error, but
  conditional on be_quiet may not print it.
* The record_warning function always records a warning,
  but conditional on be_quiet may not print it.
* The record_verbose function only prints the verbose
  message if verbose is true and be_quiet is false.

This has allowed the following fix:
* Previously any warnings were being treated as errors
  because they incremented error_message_count, but now
  we properly return an exit status of 1 if there are
  warnings but output was generated.

All of this allows localedef to correctly decide if errors,
or warnings were present, and produce the correct exit code.

The locale and iconv programs now also use record-status.h
and we have removed the WITH_CUR_LOCALE hack, and instead
have internal push_locale/pop_locale functions centralized
in the record routines.

This patch changes the remaining uses of the old nonstandard u_intN_t
types in glibc to use the C99 uintN_t instead, except for the
definitions of those typedefs and the tests of them in the c++-types
test.  This follows the previous such fix for libm, and being
consistent in using uintN_t makes sense as a global cleanup.

Tested for x86_64, and with build-many-glibcs.py.

posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar
to what was done with libc-diag.h, I have split the definitions of
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN
to a new header, libc-pointer-arith.h.

It then occurred to me that the remaining declarations in libc-internal.h
are mostly to do with early initialization, and probably most of the
files including it, even in the core code, don't need it anymore.  Indeed,
only 19 files actually need what remains of libc-internal.h.  23 others
need libc-diag.h instead, and 12 need libc-pointer-arith.h instead.
No file needs more than one of them, and 16 don't need any of them!

So, with this patch, libc-internal.h stops including libc-diag.h as
well as losing the pointer arithmetic macros, and all including files
are adjusted.

        * include/libc-pointer-arith.h: New file.  Define
	cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and
        PTR_ALIGN_DOWN here.
        * include/libc-internal.h: Definitions of above macros
	moved from here.  Don't include libc-diag.h anymore either.
	* posix/wordexp-test.c: Include stdint.h and libc-pointer-arith.h.
