* org-bbdb.el (org-bbdb-anniv-extract-date, org-bbdb-make-anniv-hash):
Fix org-bbdb anniversary functionality to accommodate bbdb 3.x.
There are two major changes in bbdb 3.x that need to be taken into
account. The first is that `bbdb-split' reverses the order of its
parameters in 3.x. The second is that `bbdb-record-getprop' is
replaced by bbdb-record-note in 3.x.
