Remove the Named_Mutex_Holder and associated code. Convert all uses to

instead allocate a reference to a mutex locally and use the more typical
Mutex_Holder RAII object.

Named_Mutex_Holder (and in particular the string->mutex mappings contained
in the global state) have been found to be pretty expensive in at least
some situations (see post by Jack Cummings to monotone-devel 2008-03-12),
and doesn't really buy us that much in terms of ease of use. Also, it
relies on the global state object, which has shown itself to be a rich
source of race conditions and locking bugs. The intent is to incrementally
remove all of the shared / global state and require applications to maintain
that state where necessary.
