Changes to EDTK since candidate #2

	- now requires R11B-3 or later due to new erl_driver APIs
(has been tested with R11B-4)
	- a few bug fixes (some important -- e.g. edge-cases during
driver shutdown)
	- better control of debug logging

Changes to the BDB driver since candidate #2

	- a lot of stress testing and performance testing
	- several important BDB patches from Oracle (mostly for
replication), resulting from testing, plus a script to apply the patches
correctly
	- various driver bug fixes (some important) and optimizations,
resulting from testing
	- some driver API tweaks for consistency (minor
incompatibilities with previous candidates, but the APIs should be
stable now)
	- a minor new feature: convenience functions for doing
distributed transactions against masters of separate replication groups
	- support for BDB's DB_MULTIPLE(_KEY) feature (efficient bulk
retrieval of consecutive key/records) -- see c_get_multiple
	- new example code & explanatory notes for using the replication
APIs (similar to the existing non-replicated example)
