432e16cb58 Unify error handling of bundled and external libgd
There's no need anymore to call an own error handler directly. Instead we
register our error handler and call libgd's error functions (which will
forward). We do this regardless of compiling with the bundled or an external
libgd.

The PHP binding for this feature will be submitted as a separate PR.

replaced static gdPngJmpbufStruct, which is afraid of being shared with
several threads, by a couple of auto variables.

8d6cfb797b Synchronized bundled GD library with GD 2.0.17
. GD is now thread-safe thanks to wrappers around freetype library
 . Significant optimization to png writing code.
 . Miscellaneous fixes.
Fixed memory leak inside php_imagettftext_common()
Make ext/gd compile with GD 2.0.17+ (gdFreeFontCache() is not avaliable)

# One very useful feature that I still need to add support for in our
# interface to the lib is the support for png compression for imagepng().

b08f247f32 Fixed a crash that occurs during the last step of png/jpeg -> gd2 -> png/jpeg
conversion. The same crash still occures with png/jpeg -> gd -> png/jpeg, because
apparently gd format cannot handle truecolor images.
Turned off debug messages inside gd_gd2.c.

d9ecd30cc4 Changed memory allocation wrappers to macros, so that it is possible to see
where the memory leak is happening.

a24534a1ed Update bundled gd library with relevant changes from gd-2.0.4
I still need to add a configure check for the gdIOCtx struct
changes so building against older external gd libs will work again.

6d1dc8141c Apply that patch I wrote ages ago that fixes some problems with true-color
vs palette based handling.
Also implements the gdImageStringFTEx function.

7a8cade379 Initial commit of the built-in libgd based on GD-2.0.1
This initial checkin has no changes to any of the libgd code so it can
be used as a basis for diffs.  It also will not build currently because
of this.  The PHP gd checks need to be incorporated along with a bit of
other config magic.  It also shouldn't break the build and will only
take effect if you use --with-gd=php right now.
