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.)

There was little point in returning EINVAL when not: Comparing (A,B)

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...)

bugfix for mdb_cursor_put with MDB_MULTIPLE
...
If the variable dkey.mv_size is non-zero, then it means dkey
contains some original data which has to be put back in the
child db, typically when the child db has just been created.
But when using MDB_MULTIPLE, if this variable has not been
reset to zero, we may come back to this section and wrongly
think that there is some original data to be taken care of.
