Summary:                    [patch] Fix/improve transaction/dialog-matching in
pedantic mode
Description: 
Attached patch fixes the following issues in chan_sip:

1) Use astobj2 as a true hash table instead of doing a 'fancy' linear
searchg over the entire list trying to find the correct entry.

2) Fix tag matching. Currently in pedantic mode it is impossible to handle
a call that is being forwarded by a proxy, eg receiving a 183 (client, no
answer) and a 200 (voicemail) from 2 different UA's.

3) Fix spiralling calls. Each new branch creates a new pvt.

4) Part of 2) is to not clear the SIP_PAGE2_DIALOG_ESTABLISHED flag on a
BYE, to be able to absorb retransmissions.


I'm sorry this is all in one patch, but I'm a little time contraint to
split them now.
