Update to 0.27:

pkg-config 0.27
===

 - Drop usage of popt for equivalent API in glib2.
 - Add back an internal snapshot of glib2 to break circular dependency.
   This can be used by passing --with-internal-glib to configure. On
   Windows it may still be required to use an installed glib.
 - Fix --exists to check for Requires and Requires.private. This ensures
   that all necessary packages are installed prior to using --cflags,
   --libs, etc.
 - Various fixes for MinGW which should allow it to be used unpatched on
   that system.
 - New autoconf macros PKG_INSTALLDIR and PKG_NOARCH_INSTALLDIR to help
   determine the .pc file install directory.
 - Fix handling of --exact/atleast/max-version vs. =/>=/<=.
 - Fix errors in man page source.
 - Ensure testing only searches in the check directory.
 - Bump glib requirement to 2.16 to avoid deprecated
   g_win32_get_package_installation_subdirectory().
 - Autotools refresh and update. The required versions now are
   autoconf-2.62, automake-1.11 and libtool-2.2.
 - Use g_alloca from glib instead of figuring out alloca ourselves.
 - Remove search for setresuid & setreuid only needed for internal popt.
 - Bugs fixed: 833, 2458, 5214, 5326, 5703, 6074, 8653, 9135, 9143,
   9584, 10652, 11464, 14396, 17053, 23922, 28776, 29011, 29801, 31699,

pkg-config 0.26
===

 - Build system fixes
 - More tests
 - pkg.m4 fixups which makes autoconf 2.66 happier.
 - Drop support for legacy -config scripts.  Those should already be
   gone and cause problems in cross-compilation environments.
 - Drop embedded glib
 - Fix up pkg.m4 to handle the case of --exists working and --cflags
   or --libs failing.
 - Various documentation updates
 - Allow $() through without escaping it.
 - Add --with-system-include-path instead of hard-coding
   /usr/include.

Log message:
Squash a C++ism: Variable declarations only at the beginning of a block.
Found while building on NetBSD 1.5.

Log message:
patch-ab is upstream now (PKG_CONFIG_LOG support).  Remove the patch to
avoid crashing with double free on glibc.

Bump PKGREVISION for new "not crash" functionality.

Log message:
Changes 0.25:
* 0.24 included a too strict whitespace/shell metacharacter filter
  leading to some legal characters like = and : being escaped in the
  output.  This has been fixed.
* when building with newer and external libpopt, it would be confused
  over being asked to split an empty string, leading to errors with
  packages that included empty fields in their .pc files.
* Make the COPYING file explicitly GPLv2.  The COPYING file in 0.24
  was inadvertently GPLv3 rather than the correct GPLv2.
* Minor changes to documentation

Changes 0.24:
* Fix up bug in PKG_CONFIG_SYSROOT handling which mangled non-I and
  non-L arguments
* Put /usr/lib/pkgconfig and /usr/share/pkgconfig into the default
  search path when no prefix is passed to configure.
* Portability fixes for Windows and NetBSD
* Various man page updates
* Add logging support to log how pkg-config is being called.
* Skip Requires.private unless we need them for Cflags
* Add a variable, pc_path to the compiled-in pkg-config package that
  you can query for the compiled-in PKG_CONFIG_PC_PATH.
* Various updates to pkg.m4.
* Update rpmvercmp with bugfixes from upstream.
* Add introductory guide to pkg-config, thanks to Dan Nicholson for
  the patch.
* Add listing of variables in a package
* Make it possible to use external popt.
* Add --print-provides and --print-requires(-private) options
* Add support for paths containing whitespace and shell metacharacters

Set or updated LICENSE

Log message:
Add X11BASE/lib/pkgconfig and /usr/lib/pkgconfig to the default path if
they're relevant.

Bump PKGREVISION.

Log message:
The va_copy configure checks for the included glib1.
So on FreeBSD before 5 default to glib_cv_va_copy=no.
(Time to upgrade :)

Log message:
Add glib_cv_rtldglobal_broken=no for internal glib-1.2.10 as devel/glib doing.
While here, cross-compilation support again.

Log message:
Avoid duplicate main() in va_copy tests as reported by Dan McMahill.
