FS-5402 --resolve the problem is ent originate has many channels and many causes to parse so we need to check it against all the causes

FS-5379: --resolve fix skinny phone codec agreement issues due to incorrect hardwired ptime, update field names for future coding to be more descriptive

Catch single channel RESTART/RESTART ACK events for non-B-channels,
that would lead to a NULL pointer dereference, because those do not have
per-channel private data (chan->call_data = chan_priv == NULL).

FS5202.

Theoretical memory leak where if attr_init failed, then check would have still been malloc'd but not used.

Minor code cleanup. calling va_start without calling va_end doesn't leak does it? Either way, it's fixed now.

full_contact must be freed by sofia. There isn't a chance of this having blown anything up, but Coverity is right that this should be initialized with NULL to be safe against future refactors.

Was causing a very small leak on naptr lookups. Upon review just happened to be a typo missing a bang.

My bad. some how a make didn't catch this issue after a cleanup refactor. In this instance buf is being treated as an 8 byte number, not a pointer.

Coverity reported an Uninitialized pointer read. Upon further digging it appears that there is a code path where incoming packets can come in out of order, so this section of code tries to see if it can find the missed packets. As per FS-5202 there is a case where under heavy load the packet exists, and has most of the packet parsed, but still has a NULL pointer for the packet buffer. These two lines would at least help detect the edge case.
