Resolves: bug 214851

Bug Description: integrating db43 into ds70
Reviewed by: nkinder (Thanks!)
Fix Description: I took the original diffs posted by Ulf and merged them in with our code which has changed slightly since the diffs were originally generated.  I also put #if directives like the following:
#if 1000*DB_VERSION_MAJOR + 100*DB_VERSION_MINOR >= 4300
... db43 features ...
#else
... db42 features ...
#endif
so that we can use both db42 and db43.
Platforms tested: RHEL4/FC5
Flag Day: no
Doc impact: no
