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.

---------------------------------------------------------------------- 
Attched the sip_object_counter.patch to fix the second issue, that loading
realtime peers/user with rtcachefriends=yes  increase the static peer/user
objects counter (speerobjs/suserobjs) And "sip prune" decrease the counter
for realtime peer/user objects (rpeerobjs,ruserobjs) which leads to the
effect, that the counter for rpeerobjs and ruserobjs becomes negativ.

Based on the assumption, it is intentional, that if rtcachefriends is yes,
then the realtime peers/user are counted as static peers/users?
