Minimal perfect hashing code generator

The program mph tries to generate an order preserving minimal perfect hashing MPH function for the set of keys, one per line, on stdin. Each key can be at most 4095 characters long see keys.h to increase this limit, and the keys must be unique. If mph terminates, it emits a language independent binary or text representation of the MPH function on stdout. To generate a usable hash function, this output should be fed to a language dependent filter, like emitc.
