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.

Check DB flags when refreshing a stale MDB DBI.

It's hairy to figure out when a DBI is valid. Catch destructive

mdb_cursor_prev,mdb_cursor_next: Fix return value.
...
Return mdb_node_read()'s return value if it fails, not 1.
(Can happen if mdb_page_get() fails and NDEBUG is #defined.)

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).

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

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.

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.

Very large single transactions will fail. It's not just a problem when
nested transactions are used. We could make this dynamically sized,
