Added support for an embedded 'BDF ' table within SFNT-based
bitmap font files. This is used to store atoms & properties from
the original BDF fonts that were used to generate the font file.
the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
and is used to implement FT_Get_BDF_Property for these font files.
At the moment, this is still experimental, the BDF table format isn't
cast into stone yet.

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..
