* src/bdf/bdflib.c (_bdf_readstream): Allocate `buf' dynamically. 

(_bdf_parse_glyphs): Use correct size for allocating
`font->unencoded'.
(bdf_load_font): Free array conditionally.
Return proper error code in case of failure.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Make it more robust against
unusual fonts.
