Bradley C. Kuszmaul 8511ea7372 Log db close so that recovery will work right if the same db is opened and closed repeatedly.
Also the file numbers can thus be reused.
Don't pass the BRT into the flush commands, since the BRT may no longer be present.
Put a counter in to see how many rollback records are present.  (Addresses #698.)
Increment the file version to 4.
Fixes #545, #703.

Note: All the tests pass except
 * Many cxx tests are getting valgrind errors.  (Addresses #716.  Possibly causes #716.)
 * {{{test_log9.recover}}} fails with "Binary files ... differ".  These will presumably be fixed by #711 or #714.  (Addresses #711, #714.)
 * {{{test_log10.recover}}} fails.   There are two failures:
  1. A valgrind problem (see #718.)  (Addresses #718.  Possibly causes #718.)
  1. The "Binary files ... differ" issue.
