This introduces stricter library/header file checking for the Berkeley DB
library.  Since multiple versions can be installed simultaneously, it's
crucial that you only select libraries and header files which are compatible
with each other.  Version checking is done from highest version to lowest.
Building using version 1 of Berkeley DB is disabled by default because of
the hash file bugs people keep rediscovering.  It can be enabled by
uncommenting a few lines in setup.py.  Closes patch 553108.
