Summary:                    [patch] [regression] "sip prune" does not clean the
relevant peer objects -> memleak
Description: 
a "sip prune realtime peer" cmd does not delete/clean the relevant Peer
object.
So if you extensively use "sip prune" cmd with sip realtime, you have a
nice mem leak. on one of our asterisk e.g.:  

asterisk -rx'sip show objects' |grep static
-= User objects: 1944 static, -359 realtime =-
-= Peer objects: 833682 static, -832764 realtime, 0 autocreate =-

so we have 833682! peer objects, but real peer number is 1944 (we prune
only the peer) so asterisk use around 500MB with this 833682 Peer objects.

chan_sip: fix broken realtime peer count, fix memory leak

This patch addresses two bugs in chan_sip:

1) The count of realtime peers and users was off.  The increment checked
the
value of the caching option, while the decrement did not.

2) Add a missing regfree() for a regex.
