This patchset adds information about jitter buffer used in rtpdec.
The first patch prints as warning when jitter buffer is full.
The second patch prints as verbose jitter buffer size set by default in
libav headers or by application.
The third patch prints as waring when max delay on jitter buffer is
reached

Those traces are helpful to know the origin of decoding issues.
Indeed a jitter buffer full or a max delay reached will lead to packet
reordering failure and then to video decoding failure.

Change-Id: Ic10a6f2894cec9732b7fbbe3a76ccdd3c4bb858a

This patchset allows ring application to tune 2 parameters of
libav jitter buffer:
- buffer size: maximal amount of packets to be queued
- packet delay: maximal amount of time a packet can be queued

Tuning those values allows correct handling of packet reordering issues
and network jitter.
Notice that for the moment default libav values are set.

jitter buffer size is by default equal to 10.
We see often packets reordering (on internet) that can not be managed
by jitter buffer sized to 10. We increase the jitter buffer size to 30.

Notice that it would lead to more latency and thus potentially to
desynchronisation

This supports both simple and multipart content types.

*WARNING* the daemon API has not changed; however the previous
implementation was not RFC compliant and thus messages sent from or
received by a previous version of the daemon will not be interpreted
correctly. Additionally the behaviour of the API has slightly changed.
It will no longer split multiple message pairs received in the
map<string, string> into multiple, separate SIP messages if they do not
all fit into one. If there is only one pair in the map, then a message
with a single content-type will be created and sent. If multiple pairs
exist, then a multipart/mixed type message will be created. If the
created message is too large to be sent, then no parts will be sent.

Support for storing the URI of the original sender is dropped for now as it
was not being used by the clients and the implementation was buggy.

The APIs for creating XML recipient lists as defined by RFC 5365 remains
but is no longer used for now.

When bitrate is changed, new RTP session created must rely
on RTP sequence of previous RTP session in order to provide
continous sequence numbers.
This patchset ensures to keep last RTP sequence updated correctly
ensuring that no new packet will be sent when bitrate change is performed.

RTP packet maximum size must rely on maximum MTU size.
Networks such as ADSL include PPPoE header that reduce maximum
payload size.
Notice that packets higher than MTU would lead to fragmentation
by routers. With high bitrates in video, we want to avoid that.

This patch proposes to reduce the maximum UDP payload size allowed
to RTP to a value safe for PPPoE MTU.

This value has been computed as follow:

Ethernet MTU          = 1500 bytes
PPPoE headers        -= 8
IP headers           -= 24
UDP headers          -= 8
----------------------------------
Total for RTP payload = 1460 bytes

Some codecs, as h264, use a default keyframe rate based on frame count.
As example, on h264 this rate is one IFrame each 250 frames.
So this rate is sensible to fps changes, that ofen happens with
output type (images, frame size, screen casting, etc).
Using a rate based on fps seems more viable solution.

Moreover, in order to handle video artifacts in case of missed packets,
we want to send more keyframes so that artifacts will be seen for
a shorter period.

Note: the drawback of this solution is an average bitrate higher than
before as I frames are bigger than P frames.

IO events were handled by a unique thread owned by IceTransportFactory.
This patch changes that by creating a thread per IceTransport instance.

This improves a bit (on multiple-threaded architectures at least)
events handling as not all events handler run at the same speed
(SIP events are slow, Media IOs need low overhead).
