ce6335b0d9 Cleanup for TLS key and read-only filesystem.
Move key init into mdb_env_setup_locks().
Don't create unused TLS key when read-only filesystem.
Drop internal flag MDB_ROFS, we can instead test either
!me_txns, !mt_u.reader or me_lfd==INVALID_HANDLE_VALUE.

0cccf79a02 Fix mdb_rebalance
Need to check NUMKEYS as well as fill threshold, when deciding
whether to change anything. Don't let the page drop below the
minimum number of keys.

mdb_dbi_close() must allow any dbi < maxdbs, since opens in an
uncommitted txn don't increment env->me_numdbs.

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.
