Merge branch 'jh/memihash-opt'

The name-hash used for detecting paths that are different only in
cases (which matter on case insensitive filesystems) has been
optimized to take advantage of multi-threading when it makes sense.

* jh/memihash-opt:
  name-hash: add test-lazy-init-name-hash to .gitignore
  name-hash: add perf test for lazy_init_name_hash
  name-hash: add test-lazy-init-name-hash
  name-hash: perf improvement for lazy_init_name_hash
  hashmap: document memihash_cont, hashmap_disallow_rehash api
  hashmap: add disallow_rehash setting
  hashmap: allow memihash computation to be continued
  name-hash: specify initial size for istate.dir_hash table
