Merge branch 'kb/fast-hashmap'
Improvements to our hash table to get it to meet the needs of the msysgit fscache project, with some nice performance improvements. * kb/fast-hashmap: name-hash: retire unused index_name_exists() hashmap.h: use 'unsigned int' for hash-codes everywhere test-hashmap.c: drop unnecessary #includes .gitignore: test-hashmap is a generated file read-cache.c: fix memory leaks caused by removed cache entries builtin/update-index.c: cleanup update_one fix 'git update-index --verbose --again' output remove old hash.[ch] implementation name-hash.c: remove cache entries instead of marking them CE_UNHASHED name-hash.c: use new hash map implementation for cache entries name-hash.c: remove unreferenced directory entries name-hash.c: use new hash map implementation for directories diffcore-rename.c: use new hash map implementation diffcore-rename.c: simplify finding exact renames diffcore-rename.c: move code around to prepare for the next patch buitin/describe.c: use new hash map implementation add a hashtable implementation that supports O(1) removal submodule: don't access the .gitmodules cache entry after removing it
