intl: Merge with gettext version 0.19.3

This patch merges the latest release of gettext into the intl
subdirectory. The initial motivation was to include the plural.y
changes which enable building with bison 3.0, but the majority
of the other changes are merely cosmetic so it seemed like merging
the whole directory was simpler than trying to take it piecemeal.

The merge was done by copying across the latext gettext code and
adding in a few small glibc changes that have been added over the
years that seemed beneficial, as well as a couple of small build
fixes that should be merged back to gettext. I also reverted the
gettext commit:

commit 279b57fc367251666f00e8e2b599b83703451afb
Author: Bruno Haible <bruno@clisp.org>
Date:   Fri Jun 14 12:03:49 2002 +0000

    Make absolute pathnames inside $LANGUAGE work.

As it caused localedata/tst-setlocale3 to fail and it wasn't clear
that glibc wanted that behaviour.

The merge has dropped many uses of __glibc_likely/unlikely. This is
intentional given that it eases merging. It seems to me that the cost
of continually rewriting these lines when merging and the risk of adding
bugs when doing so outweighs the benefits of using these macros when
code is shared with another project.

Tested with make check on x86_64.

ChangeLog:

2014-12-11  Will Newton  <will.newton@linaro.org>

	Merge gettext 0.19.3 into intl/.

	with the date ranges taken from the glibc copy.

	* NEWS: Add gettext merge to 2.21.
	* intl/bindtextdom.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	Use gl_* locking primitives rather than __libc_* ones.
	Use __builtin_expect rather than __glibc_likely/unlikely.
	* intl/dcgettext.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	* intl/dcigettext.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	(INTDIV0_RAISES_SIGFPE): New define.
	Use gl_* locking primitives rather than __libc_* ones.
	Include eval-plural.h instead of plural-eval.c.
	Use __builtin_expect rather than __glibc_likely/unlikely.
	* intl/dcngettext.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	* intl/dgettext.c: Likewise.
	* intl/dngettext.c: Likewise.
	* intl/plural-eval.c: Renamed to...
	* intl/eval-plural.h: ...this.
	* intl/explodename.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	(_nl_explode_name): Use strchr instead of __rawmemchr.
	* intl/finddomain.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	Use gl_* locking primitives rather than __libc_* ones.
	(_nl_find_domain): Use malloc rather than alloca for
	allocation of temporary locale name.
	* intl/gettext.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	* intl/gettextP.h: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	Use gl_* locking primitives rather than __libc_* ones.
	* intl/gmo.h: Switch to gettext copyright.
	(struct sysdep_string): Move struct segment_pair outside of
	struct definition.
	* intl/hash-string.c: Use ANSI definitions and prototypes.
	* intl/hash-string.h: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	* intl/l10nflist.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	(_nl_normalize_codeset): Avoid integer overflow.
	* intl/loadinfo.h: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	(LIBINTL_DLL_EXPORTED): New define.
	(PATH_SEPARATOR): New define.
	* intl/loadmsgcat.c: Switch to gettext copyright.
	* intl/localealias.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	(_nl_expand_alias): Use PATH_SEPARATOR.
	* intl/ngettext.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	* intl/plural-exp.c: Likewise.
	* intl/plural-exp.h: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	(struct expression): Move definition of enum operator outside
	of struct definition.
	* intl/plural.c: Regenerate.
	* intl/plural.y: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	Port to bison 3.0.
	* intl/textdomain.c: Switch to gettext copyright.
	Use ANSI definitions and prototypes.
	Use gl_* locking primitives rather than __libc_* ones.
