Ignore SDP repeated in 183 and 200OK messages
in the late offer/answer, but only for the
`OA_OfferSent` OA state.

When OA generates own SDP body (e.g. case with
accepted invite in DSP), save it as established_body
for this leg, in order to be able to re-invite
this leg later.
It can happen there is still no SDP seen from the
callee side (other side), and in case we want to
send established re-invite towards this leg,
this will fail, since no SDP body seen yet.

When replying with 200OK generated by SEMS to INVITE requests,
which have no SDP body included, just answer with empty 200OK.
This sets the `OAState` of the call leg to `OA_None`.

SDP session origin id and version are limited by it's size
to 64 bits (8 bytes), that is because we are using `unsigned long long`
type for both id and version. Hence the maximum value it can hold
is two sixty-forth power, so equals: 18,446,744,073,709,551,615
In case one intentionally sets it to something like:
"o=- 18446744073709551615 18446744073709551615 IN IP4 192.168.0.1"
SEMS gets overwhelmed with that conversion inside the code make
it just to a string literal 'F'.
To overcome it, just use __uint128 (which is of 128bits size)
for the session origin id and version.

Use `unsigned long long` for SDP session id and version
instead of unsigned int.
Refactor all usage of them accordingly.
Additionally intrdouce new utils functions for conversion:
- `ulonglong2str()` - converts `unsigned long long` to `string`
- `str2ull()` - converts `string` to `unsigned long long`

Backport from the upstream to add support for body content type
application/csta+xml in INVITE and INFO requests/responses.

We don't have to change the SDP OA state, in case
the 183 response has exactly the same SDP content
(same SDP session version) as we already have seen
before in previous 183 message.
Change-Id: Ica008104c31e979cdcb352cefea39db4d1ff3c56
We have to improve AmOfferAnswer functions in terms of adding
more logging, to let the debug of the OA be more clear.
Also in parallel the refactoring is done in scope of AmOfferAnswer
in order to make reading more convenient.

Re-use existing local sdp, in case there is a sequential 183 coming,
but it has no SDP.
This will fix the cases, when:
- first 183 has been sent, and provided to the system the SDP
- second/third etc. 183 is coming, but has no SDP body
To not confuse the recipient (end subscriber) of these 183,
the media description in the scenario with 183 having no SDP body,
mustn't be changed (session id, media and attributes).
Previously the behavior was to generate local SDP with
a new session id and add sems-b2b into the media processing by that
(new media port, codecs and other attributes).
However, this change doesn't have an influence on very first 183
sent with no SDP body, because there was essentially no local SDP
saved before. So in this situation behavior is not changed.

Because of messy organizing of the code in the function,
it's not possible to read that and work with that.

If an SDP UPDATE is received after the 183, but before the 200,
SEMS fails when it receive the final ACK. In fact SEMS tries to
find the SDP content inside the ACK message itself.
The solution is copied from sems-pbx module where the issue
doesn't happen.
