Change hash_table to support a comparator type different from the
value type stored in the hash table. The 'find' functions now may
take a different type from the value type. This requires introducing
a second typedef into the Descriptor conceptual type. Change the
Descriptor concept to use typedefs value_type and compare_type instead
of T. Change all users to match.
Add usage documentation to hash-table.h.
Tested on x86-64.

2012-10-25 Lawrence Crowl <crowl@google.com>
* hash-table.h: Add usage documentation.
(template struct typed_free_remove): Clarify documentation.
Rename template parameter.
(struct typed_noop_remove): Likewise.
(descriptor concept): Change typedef T to value_type.
Add typedef compare_type. Use more precise template parameter name,
Descriptor instead of Descr. Update users to match.
(struct hash_table): Change 'find' parameters to use compare_type
instead of the value type.
