* include/bits/unordered_map.h (__unordered_map): Remove.
(__unordered_multimap): Remove.
Add aliases for __umap_traits, __umap_hashtable, __ummap_traits,
__ummap_hashtable.
(unordered_map): Derive from __umap_hashtable.
(unordered_multimap): Derive from __ummap_hashtable.
* include/bits/unordered_set.h (__unordered_set): Remove.
(__unordered_multiset): Remove.
Add aliases for __uset_traits, __uset_hashtable, __umset_traits,
__umset_hashtable.
(unordered_set): Derive from __uset_hashtable.
(unordered_multiset): Derive from __umset_hashtable.
* include/bits/hashtable.h (__cache_default): New, consolidated
cache defaults for _Hashtable. Adjust comments for doxygen.
(_Hashtable): Consolidate bool template parameters into new,
_Traits class. Inherited base classes synthesize _Hashtable in
CRTP via original 10 parameters. Prefer using declarations to
typedefs, add __node_type, __bucket_type, etc. Push many nested
types down hierarchy to _Hashtable_base. Add constructors
necessary for top-level unordered_containers. Consolidate insert
member functions and logic in new base class, __detail::_Insert
and __detail::_Insert_base.
(_Hashtable::operator=(initializer_list)): Add.
* include/bits/hashtable_policy.h: Convert to doxygen markup.
(_Hashtable_traits) New. Consolidate bool template parameters here.
(_Insert, _Insert_base): New, consolidated insert member functions.
(_Map_base, _Equality, _Rehash_base): Adjust template parameters,
use base types.
(_Hashtable_base): Move type declarations useful to other base
classes into this class.
* python/libstdcxx/v6/printers.py (Tr1HashtableIterator): Update.
* testsuite/23_containers/unordered_set/instantiation_neg.cc:
Adjust traits, line numbers.
