I had already prepared this patch. Thanks for explaining why we have 
this problem now.

Note that I chose to use full specialization with std::hash<> for std::bitset and std::vector<bool>.

It also fix a versioned namespace issue when partially specializing std::hash for debug vector<bool>.

Tested under Linux x86_64 normal, debug and versioned namespace modes.

Ok to commit ?
