re PR libstdc++/29367 (pb_ds hash containers vs. _GLIBCXX_DEBUG)

2007-09-06  Benjamin Kosnik  <bkoz@redhat.com>
	
	PR libstdc++/29367
	* include/ext/pb_ds/detail/map_debug_base.hpp: From this..
	* include/ext/pb_ds/detail/debug_map_base.hpp: ...to this.
	Rename map_debug_base to debug_map_base, add std::pair output
	extractors, change duplicate map_debug_base typedef in containers
	to debug_base. Use m_store_extra_indicator for m_store_hash_indicator.
	* include/ext/pb_ds/*: Likewise.
	* include/Makefile.am: Same.
	* include/Makefile.in: Regenerate.
