Use wxConvAuto in wxFile::Write().

For consistency with wxFFile.

No real change, as wxConvAuto will default to UTF-8 when writing.

Use wxConvAuto() in wxStyledTextCtrl::DoLoadFile().

This is both more reasonable than the current runtime encoding (the
input file is from unknown source) and more robust (it can handle UTF-*
encoded files transparently).

Update the version of Expat used to 2.1.0.

Merge with the latest version, mostly discarding our changes to 1.95.6 as they
seem to be unnecessary any longer, keep just bakefile-specific addition to
configure.

Also update our own makefile to define HAVE_EXPAT_CONFIG_H which is now needed
by Unix build.

Closes #11677.

Add files necessary to run Expat configure.

This should have been part of the previous commit (r74436).

Remove the TOOLKIT test from msvc-headers-setuo-h definition.

This is unnecessary now that TOOLKIT is back to being a constant again and
results in errors if GTK TOOLKIT is enabled.

Closes #14965.

Correct wxTranslations docs: CWD is not searched.

The documentation incorrectly stated that the current working directory
is searched for translations.  This isn't the case (and wouldn't be a
good thing to do).

See #12498.

Improve translations lookup logging.

Log match directory in GetAvailableTranslations().  Log search paths
with one directory per line, for better readability when debugging.

Don't look for catalogs in AddCatalogLookupPathPrefix() path directly.

Previously, the prefix directory itself for searched for catalogs, in
addition to prefix/lang/LC_MESSAGES and prefix/lang.  This never made
much sense, because only one catalog could be in such place, instead of
multiple catalogs for more languages.  It also prevented successful
identification of catalog's language and didn't work with
GetAvailableLanguages().

Remove this misfeature and update the documentation accordingly.  Update
OS X-specific code so that it continues to work (it previously depended
on this behavior).  As a side effect, *.lproj directories are now
recognized in all search prefixes, not just in Resources.

See #12498, #15253.

Define XML_STATIC for Expat build to fix linking of Windows DLLs.

The new Expat assumes it's built as a DLL by default, define XML_STATIC to
indicate that this is not the case as we always build it as a static library.

Compilation fix for r74440 and STL builds.

Define XML_STATIC in Expat header instead of Expat projects.

This reverts r74444 and defines XML_STATIC unconditionally in Expat sources
themselves as we always use the built-in Expat as a static library, so this
solution is simpler and more portable.

Regenerate configure after libwxscintilla linking changes.

This should have been done together with the changes of r74425, as
autoconf_inc.m4 had changed, configure should have been regenerated too.

Add instructions for upgrading third party libraries.

Describe the process for upgrading the libraries for which we already use svn
vendor branches.

Merge libpng 1.6.2 into the trunk.

Add pngprefix.h file generated by libpng configure/make process (which we
don't run during wxWidgets build, so this is something that will need to be
redone manually whenever libpng is upgraded, the procedure for doing this is
documented in docs/tech/tn0025.txt) in order to use "wx_" prefix for all
libpng public symbols. This should avoid at least some problems due to the
conflicts between the built-in libpng and shared libpng loaded into the
process as GTK+ libraries dependency under Unix.

Also rename wx_png_{warning,error} to use upper case PNG for consistency with
wx_PNG_stream_{reader,writer} and to avoid conflict with png_{warning,error}()
which we now rename to have "wx_" prefix.

Closes #14157.
