added the new configuration file "ftstdlib.h" used to define
aliases for all ISO C library functions used by the engine
(e.g. strlen, qsort, setjmp, etc...)
this eases the porting of FreeType 2 to exotic environments like
XFree86 modules/extensions..
also removed many #include <string.h>, #include <stdlib.h>, etc...
from the engine's sources where they're not needed..
(some platforms don't provide this ANSI function !!)
some changes to "ftsystem.c" implementations in order to use
the new memory debugger on Unix, VMS and Amiga too !!
