af09d8b96a Fixed Bug #66815 imagecrop(): insufficient fix for NULL defer CVE-2013-7327 
This amends commit 8f4a537, which aimed to correct NULL dereference because of
missing check of gdImageCreateTrueColor() / gdImageCreate() return value.  That
commit checks for negative crop rectangle width and height, but
gdImageCreate*() can also return NULL when width * height overflows.  Hence
NULL deref is still possible, as gdImageSaveAlpha() and gdImagePaletteCopy()
is called before dst == NULL check.

This moves NULL check to happen right after gdImageCreate*().  It also removes
width and height check before gdImageCreate*(), as the same check is done by
image create functions (with an extra warning).

dd0399f5c6 We need both gdImageCreateFromJpeg* and gdImageCreateFromJpeg*Ex 
The new (Ex) functions are used with the new ignore_warning parameter

The standard functions are used in _php_image_create_from_string,
sent as a function pointer, and call without this optional parameter.
