Reduce realloc syscall overhead for FT2232 and bitbang
FT2232 ran realloc() for every executed command. Start with a big enough buffer and don't touch buffer size unless it needs to grow. Bitbang was slightly better: It only ran realloc() if buffer size changed. Still, the solution above improves performance and reliability. Corresponding to flashrom svn r780.
