Major changes:
- support dealing with anonymous calls
- support for SIP Trunks
- various interoperability issues have been resolved
(Snom phones no longer require the "broken registrar" setting)
New plugins:
stripheader, codecfilter, siptrunk, fix_DTAG, fix_fbox_anoncall
In the port, don't build useless static versions of the modules in
the first place instead of deleting them later.
