Add MDB_NOMETASYNC env option.

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

ends. Cursors in parent transactions are updated when their child
transaction commits.

mdb type cleanup: Consistent reader count types.

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.
