ITS#7598 Tweak MDB_<NEXT/PREV>_NODUP,fix mdb_stat.
...
MDB_NEXT_NODUP, MDB_PREV_NODUP: Allow for non-MDB_DUPSORT databases.
No mdb.c code changes needed.

ITS#7598 mdb_dbi_open(named DB): Check mainDB flags.
...
Reject attempts to open named databases if the main
database has flag MDB_DUPSORT or MDB_INTEGERKEY.
DUPSORT would require an xcursor for the DB, INTEGERKEY
would expect the DB name to be a binary integer.

Simplify/cleanup mdb_cursor_init, C_ALLOCD.
...
No real change.
mdb_cursor_init() checks if it needs mx, so pass it unconditionally.
Set C_ALLOCD for shadow cursors, for clarity. (It was always set as
it should anyway from the origin cursor, which would have C_ALLOCD.)

mdb_dcmp(): Assume the database has MDB_DUPSORT.

There was little point in returning EINVAL when not: Comparing (A,B)
and (B,A) would claim (A > B && B > A), which could confuse callers.

mdb_cursor_close need not peek inside a possibly-freed readonly txn.

Close cursors when commit(writer). Factor out code.
...
Close remaining cursors when committing a write txn. The doc says this
happens, and it avoids cursor tracking when updating mainDB + freeDB.
Rename mdb_cursor_merge() -> mdb_cursors_close() for code reuse,
and add a merge option. Simplify its loop a bit.
Factor out cleanup of DBIs.

Avoid assert
...
Due to underfilled branch page. We're in the process of merging/moving
nodes to it because we already know it's underfilled. Took this approach
rather than just removing the assert in mdb_page_search_root, because
that assert may yet catch other situations we don't know about.
(Although, it has been there since the original commit of mdb.c and
has never triggered any other times...)
