stat/fstat aren't compatible with GStatBuf on Windows in all cases.
Since we don't really need the file descriptor anyway here replace it with
a g_stat call.
This fixes a compiler warning with 64bit mingw.
And lets us remove this scary ifdeffery.
Instead of having the IconTheme have a hashtable that owns
individual strings and then IconThemeDirSize have a similar
hash (but with the strings owned by the other hash), we
have a consecutive memory chunks where we store the icon names
and then the hashtable has pointers into this.
This means we can avoid a bunch of individual strdup()s in a
way that is less fragmented and wastes less space. Additionally,
since we do an initial lookup anyway we have the internalized
icon name during lookup which means we can use g_direct_hash/equal
instead of g_str_hash/equal making the lookup faster too.
It turns out with the icon cache now using the virtual SYMBOLIC_PNG_SUFFIX
flag the two enums are now identical, so lets just use one of them, the
one GtkIconCache (so we move it to the header).
This lists the icons in a particular director, with their flags in a
hashtable. We also convert from "icon.symbolic" + SUFFIX_PNG to
"icon" + SUFFIX_SYMBOLIC_PNG.
The g_print documentation explicitly says not to do this, since
g_print is meant to be redirected by applications. Instead use
g_message for logging that can be triggered via GTK_DEBUG.
With Mingw-w64 fstat() can be an inline function that
calls _fstat32() or _fstat64(), depending on some macros.
And if LFS is enabled, fstat() is defined to turn into
_fstat32i64() or _fstat64(). And some/all of the above
might also be macros as well. Side-step all that mess
and excplicitly re-define fstat as _fstat32, which is
guaranteed to use a version of "stat" struct that
has 32-bit size and time fields, which is what we want.

The icon data in GttkIconInfo->data is currently owned by the
IconThemeDir->icon_data hashtable. However, on e.g. a theme change
blow_themes() destroys the dirs and thus the data, meaning any
outstanding GtkIconInfo points to stale data.
We solve this by adding a refcount to GtkIconData and reffing it
from GtkIconInfo.

find_image_offset returns 0 if it failed to find a matching image.
Check this return value in _gtk_icon_cache_get_icon to avoid
making bad memory accesses later.

_fstat32 is only introduced with msvcrt80.dll (i.e. Visual C++ 2005), in
which using this function will break compilation with MinGW, which links
against msvcrt.dll. The msvcrt.lib in the Windows DDK which links to
a later incarnation of the msvcrt.dll in later Windows systems may have
this symbol defined, but that needs to be checked upon to be sure.
Thanks to Dieter Verfaillie for pointing out this problem.
Thanks to Kean Johnston for pointing this out.
There are a few places in GTK that use "struct stat",
and then g_stat(), rather than using GStatBuf.This breaks things on
Windows. Since the size of struct stat can vary depending on other
flags specified, this has the potential to cause overwrites and is
trivial to fix.
Based on patch submitted by Kean Johnston
Preferrably should be made just into a local variable for libgtk like
_gdk_debug_flags for libgdk. But for now used by
gtk/tests/textbuffer.c and modules/printbackends/cups/gtkprintbackendcups.c.

Two optimizations for icon cache lookups.
* gtk/gtkiconcache.[hc]:
* gtk/gtkicontheme.c: Remember the directory index for
subdirectories, instead of running over the directory list
again and again.
* gtk/gtkiconcache.c (find_image_offset): Remember the last
chain and try it first; this helps with the the usage patterns
in gtkicontheme.c, where the same icon is queried for a lot
of subdirectories.

* gtk/gtkiconcachvalidator.[hc]: Add an icon cache validator.
* gtk/updateiconcache.c: Validate the generated cache before
moving it in place. Also add a --validate option to validate
an existing icon cache.
* gtk/gtkiconcache.c: Validate icon caches before using them.
* gtk/Makefile.am: Integrate it.

* Commit a patch by Behdad to fix typos, omissions and other
errors in the symbol aliasing, and add checks for local PLT
entries. (#354687, Behdad Esfahbod)

* gtk/gtkicontheme.c (load_icon_data): Don't leak the keyfile
parser in the error case.
* gtk/gtkicontheme.c (load_icon_data, free_unthemed_icon)
(icon_data_free, load_themes):

Store builtin stock icons in an icon cache, instead of
populating a hash table with pixbufs at startup, to save both
memory and startup time.
* gtk/stock-icons/*: Reorganize the icons in a directory structure
suitable for gtk-update-icon-cache, and rename them to match the
stock ids.
* gtk/gtkiconcache.[hc]: Support non-mmapped icon caches, and
add _gtk_icon_cache_has_icon_in_directory().
* gtk/updateiconcache.c: Support a --source <VARIABLE> argument
to store the contents of the icon cache in a C header.
* gtk/gtkbuiltincache.h: Generated private header which contains
the icon cache for the builtin icons.
* gtk/gtkicontheme.c: Create a GtkIconCache for the builtin
icons, and use that in addition to the hash table whenever
builtin icons are searched.
* gtk/gtkiconfactory.c: Add GTK_ICON_SOURCE_STATIC_ICON_NAME and
use it for static stock ids.
(get_default_icons): Don't add the builtin
icons to the icon theme, just register the stock ids.
(render_fallback_image): Take the fallback image out of the
builtin icon cache.
* gtk/Makefile.am: Remove stock-icons from SUBDIRS and add
the necessary machinery to rebuild gtkbuiltincache.h.
2005-08-22 Matthias Clasen <mclasen@redhat.com>
* gtk/gtkicontheme.c (gtk_icon_theme_load_icon): Add a note
regarding icon theme changes.
* gtk/gtkiconcache.c (_gtk_icon_cache_get_icon): When returning
pixbufs which are backed by the mmapped memory of an icon cache,
increase the refcount of the icon cache, so that the memory is not
munmapped away underneath the pixbuf upon icon theme changes.

* **/makefile.msc[.in] : updated
* gtk/gtkiconcache.c : <io.h> for open()
* gtk/gtkstyle.c : use G_PI instead of M_PI
* gdk/win32/gdkcursor-win32.c : implement gdk_cursor_new_from_name()
by mapping the lower case win32 api name to the respective cursor.
E.g. pass "wait" to get the IDC_WAIT cursor. Also allows to load
cursors from named resources in the executable.
(gdk_cursor_get_image) : just return NULL for now.
* gdk/win32/gdkgeometry-win32.c : implement gdk_window_move_region()
by delegation to ScollWindowEx(), untested.
