Store lock ID instead of pathname in lockfile
...
This limits the namespace which the user can meddle with for
POSIX semaphores and Windows mutexes. Their names change a
bit, they no longer have fixed lengths.

Doxygen fixes. Use DISTRIBUTE_GROUP_DOC.
...
- DISTRIBUTE_GROUP_DOC makes doxygen give several fields the
same doc: mn_hi + mn_lo in MDB_node.
- With mdb_mutex_t + mdb_mutexref_t, instead split them up.
- Don't hide a doxygen #name inside double quotes.

Clean up and comment C_UNTRACK

Don't use it as a "cursor is tracked" hint in mdb_pages_xkeep().
It's been harmless so far, but would break after mdb_cursor_copy().
Checking m0 directly short-circuits better anyway.
