ITS#7364 Limit mdb lock upgrade before sem_unlink.

Do not try shared lock when closing or after error. Track file lock
state to decide. Change meaning of *excl to reflect file lock state.

ITS#7364 Always sem_unlink() in mdb_env_open().
...
Drop the sem_unlink() error checks, which could prevent the 2nd
unlink. Instead use O_EXCL in sem_open().
This makes "open+close the database" the API for trying to clean
away the old semaphores, if they were left behind by a previous run.

Remove mdb data races. Use (txnid_t)-1 as "no ID".
...
Avoid race between numreaders++ and reading numreaders at cleanup. Make
the un-mutexed reset of reader table entry, atomic: Reset mr_pid only.
Instead check mr_pid != 0 in mdb_page_alloc()'s scan for readers.
(txnid_t)-1 as "no ID"-mark avoids a check for mr_txnid != 0.
The scan can stop when seeing an old reader.

Save pid in MDB_env instead of repeating getpid().
...
An open MDB environment does not survive or catch fork(),
so repeating getpid() was pointless.
