bbb27cde4a 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.

208e5c614d ITS#7515 Fix mdb_txn_commit(nested txn).
Don't modify the parent txn until the current txn cannot fail.
Don't assume new dirty child pgnos > dirty parent pgnos.

Page alloc/touch: Fail if child+parent dirty pages would exceed
dirty_list's maxsize. Avoids an error situation in commit.

2dbb8bb833 mdb_cursor_prev,mdb_cursor_next: Fix return value.

e4af9ee5da ITS#7515 mdb_dbi_open(): Also open in parent txns.
This makes aborting nested and non-nested txns more
similar: The new DBI is available to the surrounding
context (parent txn and MDB_env respectively).

4b67270374 mdb_page_alloc(): Handle freeDB txnid range holes.
A txn writes no freeDB entry if previous txn dropped mainDB and a read
txn prevents freelist entry reuse. This surprised mdb_page_alloc (and
mdb_txn_commit too before 65c053a6e7).

00d7a96bd5 ITS#7515 Fix MDB parent/child txn interaction.
mdb_txn_commit(child): Copy more state. Copy all of mt_dbs:
Include mainDB, and even freeDB since mdb_drop() can update
it. Don't skip DBs with unchanged root, this could break
when the new was newly opened and the old unused junk.

mdb_page_get(): Search parents' dirty lists.

c7db955a94 ITS#7517 Don't save dropped dirty MDB databases.
mdb_txn_commit's attempt to save the DB could corrupt another DB if
another thread had called mdb_dbi_open and reused the closed DBI.

Don't memmove freelist entry when chunking it. Just advance the pointer,
now that it's no longer a complex struct. Also just calculate maxfree_1pg
at startup; it's a constant during runtime.
