b9d13a29e6 Track changes to all cursors.
For any change to a page or node, update all other cursors pointing
at the same page (or node). Cursors are now stored in a linked list
off their owning transaction. Cursors are all closed when the transaction
ends. Cursors in parent transactions are updated when their child
transaction commits.

57b5fbea49 Add mdb_drop() for deleting a DB

pages to be freed in one txn.

09006ccec7 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).

b7057eb61e 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.

3501248548 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.

bf9d722bec mdb type cleanup: Consistent reader count types.
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.

c7d6c0fab3 Add a few NULL checks to defend against dumb API checkers.
Unfortunately automated checkers don't seem to read the documentation
for how APIs are expected to be used, and the C declaration syntax
isn't expressive enough to encode the documented usage.
