df81345337 Add MDB support to configure and test framework. 
Does not update the tests themselves.

In configure --help, call it "mdb database backend" instead of something
with "memory-mapped" which could confuse somebody about a memory-only DB.

0f459dd773 Cleanup, fix freelist alloc 
Don't allow new pages for free list to come from the free list.

5b3b522313 Wrap O_DSYNC in MDB_DSYNC. 
If O_DSYNC is not defined, that may be due to poor compiler options.
We could fall back to the less efficient O_SYNC, but it seems better
to let the user learn of the problem and give better compiler options.
