[Devel] Improper use of memcpy in _bdf_readstream

[Manish Singh]

While running valgrind, I got:

==23811== Source and destination overlap in memcpy(0x445087c4, 0x445087c4, 184)
==23811==    at 0x4001F9D5: memcpy (mac_replace_strmem.c:95)
==23811==    by 0x40725034: _bdf_readstream (bdflib.c:699)
==23811==    by 0x40726EB0: bdf_load_font (bdflib.c:2218)
==23811==    by 0x40727534: BDF_Face_Init (bdfdrivr.c:222)

when loading:

/usr/X11R6/lib/X11/fonts/encodings/large/jisx0201.1976-0.enc.gz

Granted, this isn't something freetype can deal with, but it looks like a
problem could happen when reading small (but valid) bdf files.

Trivial patch attached.
