FootprintHashEntry* search_footprint_hash ( const char * footprint )

Searches for the given element by "footprint" name, and loads it into the buffer.

Figuring out which library entry is the one we want is a little tricky. For file-based footprints, it's just a matter of finding the first match in the search list. For m4-based footprints you need to know what magic to pass to the m4 functions. Fortunately, the footprint needed is determined when we build the m4 libraries and stored as a comment in the description, so we can search for that to find the magic we need. We use a hash to store the corresponding footprints and pointers to the library tree so we can quickly find the various bits we need to load a given footprint.
