bug#19678: [PATCH] EUDC does not support BBDB 3.x

[Sergio Durigan Junior <sergiodj@sergiodj.net>]

This bug was opened due to a request made at:

  <https://lists.gnu.org/archive/html/emacs-devel/2015-01/msg00800.html>

As explained at:

  <https://lists.gnu.org/archive/html/emacs-devel/2015-01/msg00542.html>

With the release of BBDB 3.x, EUDC needs adjustments to properly work
with it.  Actually, after some investigation, I noticed that the only
adjustment was to replace the occurrences of 'net' by 'mail' in the
code.  The second link above contains a patch that does that, but Thomas
Fitzsimmons correctly noted (in the first link) that the patch breaks
compatibility with BBDB 2.x.

The following patch is a first attempt to implement the support for both
BBDB 2.x and 3.x.
