MFB: Fix bug #20995

directory values are optional

Synchronized bundled gd library with the latest stable GD, 2.0.6
Fixed a configuration problem with xpm.
Fixed 2 possible memory leaks in fontFetch().

Fix the test. (and indented it for easier bug spotting :)

Fixed gd 2.0.4 check

A better gd >=2.0.4 version check for non-bundled gd library.

This patch allows compilation of gd against non-bundled gd library older
then 2.0.4.

Nuke tabs.

Changed --with-gd to behave same way as --with-mysql does.

- Prevent resetting the PHP_*_DIR variables if already set.

--with-zlib-dir has to be defined here to enable phpize build

As discussed a while ago, decoding GIF images is not considered a Unisys
LZW patent violation so we can distribute read-only GIF support with
our bundled GD2. The patent also expires in 2003

As discussed a while ago, decoding GIF images is not considered a Unisys

approaching, so we can roll in write support soon unless things change.

For now, check only when not using bundled GD lib.

Added build test. Bug: #19345

This was not a good idea.

Fix build with bundled gd when builddir!=srcdir

Using --with-zlib-dir should work now with phpized builds too.

This _should_ fix those builds where gd.h might be in many places in
the system. Not guaranteed, but now the path for the found gd.h is always
first in the includes.
