Ray Lai 94b38bdb72 libdraw: replace hand-rolled realloc, preventing buffer overflow. 
The original buffer is f->nsubf*sizeof *subf bytes (oldsize) large.
Once it's full, a new buffer of (f->nsubf+DSUBF)*sizeof *subf
(newsize) is mallocated.  Unfortunately memmove() reads (newsize)
bytes from the original (oldsize) buffer, causing a buffer overflow.

By switching to realloc(), we don't need to do buffer size calculation,
memmoving, and freeing of the original buffer.
