Put all the prototypes for hashfn.c into the same header file.

Browse Source 
Previously, some of the prototypes for functions in hashfn.c were
in utils/hashutils.h and others were in utils/hsearch.h, but that
is confusing and has no particular benefit.

Patch by me, reviewed by Suraj Kharage and Mark Dilger.
