[asterisk-r2] clear_back_persistence_check equivalent

[Moises Silva]

The functionality you require is only in
http://svn.digium.com/svn/asterisk/team/moy/mfcr2-1.4 and the beta
release of Asterisk 1.6.2.

You just set the variable MFCR2_DOUBLE_ANSWER before calling Answer()

This also requires openr2 from the release-1 branch
(http://openr2.googlecode.com/svn/branches/release-1) that is the
branch that will become openr2 1.2.0 anytime soon. However, be aware I
added some changes a few days ago for DTMF/R2 support and I have not
really tested it well, I may have introduced some bug here or there
:-)
