68eda68f0b 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.

d84dee516f ITS#8557 fix mdb_cursor_last 
Optimize mdb_page_search_root(PS_LAST) when cursor is already near
last position, ignoring C_EOF flag for now.

be94a7565b 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.

d78c80d902 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.

72f875b48a Note functions which must set MDB_TXN_ERROR on failure 
Other functions depend on them to do so.
For mdb_node_read(), instead remove such a dependence.

a70200f15f Fix mdb_env_open() with MDB_VL32 
Init me_rpmutex independently of MDB_NOLOCK.
Plug leaks on mdb_env_open() failure.
Tweak mdb_env_close0() to handle the rearranged mdb_env_open().

67fb3c746a ITS#7992 Tighter utf8_to_utf16(), fix errcodes 
The 0xFFFD check seems due to misleading MultiByteToWideChar() doc.
Bad UTF-8 gives 0xFFFD in the output string, not the return value.
