Allow mdb_env_set_mapsize() on an open environment
...
The caller is responsible for making sure no transactions are
active in this process before resizing. This is slightly lighter

Less aggressive page_spill

spilling all possible pages is a waste because the majority will be
needed again. Just do 1/8th of the dirty list instead.

Fix obscure MDB_MULTIPLE bug

If a key has a single existing value, and then a put (MDB_MULTIPLE)
is done where the first of the multiple values matches the existing
value, the put would return SUCCESS without writing any of the
values. Fixed to loop to the next value as intended.

mdb_cursorpages_mark: Mark current txn and no more.
...
Ignore parent txn cursors since it is the current txn's dirty_list
which will be flushed. But check the current txn also when clearing,
since cursors can have pages which are dirty in a parent.
Check !mc_xcursor instead of !MDB_DUPSORT. Equivalent for valid
data, but a bit safer if the sub-DB flags are corrupt.

Fix mdb_reader_pid().

Treat unexpected errors as "don't know". Invert Pidcheck return
value, so nonzero including error codes = "the process may exist".
On Windows: Catch exited but still existing processes. Handle
undefined PROCESS_QUERY_LIMITED_INFORMATION.
On Unix: don't trust F_GETLK error to leave the input alone,
the fcntl() doc seems unclear.
