Make coverity happy, since this seems to spread as a tainted error
further below.

This patch inconditionally initializes the buffer we get to
nul-terminate it, whenever possible. It's a very simple solution to
catch three overly corner cases:
1) snprintf() returns -1, very much unlikely in practise.
2) msg->len == 0: In such case, I would expect this function is never
called with an empty message, but let's be safe in this case too.
3) If your buffer is empty, it doesn't nul-terminate the buffer.

SNPRINTF_BUFFER_SIZE() looks too complex, previous version maintains two
different variables to account for the remaining space in the buffer,
one of them is always decremented based on what snprintf() returns,
which may result in underflow. These variables are swapped - not used
consistently - all over this code.
Replace this macro by a simplified version, with one single parameter to
account for remaining space. This macro also deals with two corner
cases:
1) snprintf() fails, actually never happens in practise, but
documentation indicates it may return -1, so let's catch this case
from here to stick to specs.
2) There is not enough space in the buffer, in that case, keep
increasing offset, so we know how much would have been printed, just
like snprintf() does.
Thanks to Pau Espin for reporting, and Holger for clues on this.
I have run osmux_test and, at quick glance, it looks good.

Use the new macros to deal with little/big endian. Im a bit
worried to make this change due the little test coverage in
this module but in case of a typo the elements would not be
defined.

This patch splits osmo_rtp_parse in two functions:
osmo_rtp_get_hdr
osmo_rtp_get_payload
So we can validate corrent RTP header to access its fields. Then,
obtain the payload.
This patch adds the initial RTP support for libosmo-netif, it's based
on Harald's RTP support available in openBSC.
I have also added a couple of example to show how our new channel
infrastructure interacts with the RTP layer.
