Add mdb_drop() for deleting a DB
...
Allow MIDLs to grow arbitrarily, to allow unlimited number of
pages to be freed in one txn.

API change, consistency check
...
mdb_close() takes an env, not a txn.
Also, add check for stale DB records (in case some other process
wrote to the DB last).

New sorted-dup subpage support
...
Instead of converting directly to a subDB when the first duplicate
item is seen for a key, convert to a subpage instead. Allow the
subpage to grow up to the overflow limit, then convert to a subDB.
This saves a significant amount of space in a typical slapd index
database.
Currently we don't convert back to the smaller form if items are
later deleted. Probably could do that with some hysteresis, e.g.,
convert back from subDB to subpage when the size drops below
(overflow limit/2). Maybe later.

Fix 2e3bc39fa9
...
Various mistakes when converting from previous data structures.
Add a few more debug asserts/sanity checks.
Split all "if (foo) return" constructs to separate lines to allow
easier breakpoint setting.
Add mtest6 for checking mdb_split() behavior. This needs to be
expanded to check rebalance/merge cases too.

Use unsigned int for reader counts/max limits, that's the smallest
change. Don't need uint32_t when mdb_env_set_maxreaders() takes less.
Change prototypes of mdb_env_set_maxreaders,mdb_env_get_maxreaders().
Check the mdb_env_set_maxreaders() argument.
