lib: Better hashing of string values using Bernstein hash
* hash.{h,c}: (string_hash_make) Hash optimised for strings, current
implementation using Bernstein hash, which offers a good compromise
between distribution and performance.
* distribute.c: (distribute_hash_make) use previous instead of additive
string hash.
* if_rmap.c: (if_rmap_hash_make) ditto
