Add MDB_NOMETASYNC env option.
...
Just a trial. This may not make sense if we decide to split the
meta pages into their own separate file, to allow meta traffic to
reside on a separate spindle.

When putting a record, just make space for the data, don't copy it.

to determine the insert location.)

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.

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.
