ITS#7515 Fix mt_dirty_room in nested txns.
...
Fix description & code: Also ignore dirty pages hidden by
spilled pages, as they won't merge into our dirty_list.
Update it in mdb_page_flush() instead of mdb_page_spill().

ITS#7682 mdb_env_copy(): Avoid Linux O_DIRECT bug.
...
Use fcntl() to set the flag. Linux open(,O_DIRECT...) can create
the file even on failure, if the filesystem lacks O_DIRECT support.

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
weight than doing a full env_close/env_open cycle.

Less aggressive page_spill

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.
