[v2 0/9] RFC: port gas to use libiberty htab hash table

[Martin Liska]

Hello.

There's second version of the patch set where I did:
- New htab_t related functions are implemented in gas/hash.c, libiberty
  maintainer was not happy about moving them to libiberty.
- New str_hash_* function were added to support a string hash table
  based on htab_t.
- Legacy hash table is removed in gas/hash.[ch]
- Two related options are removed (--reduce-memory-overheads, --hash-size arguments)

I tested the patchset on all targets.
Thoughts?
