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.

The buffer for osmux_test is increased as the former doesn't seem to be
able to cope with the whole output.

According to RFC4867 (RTP payload format for AMR):
"The RTP header marker bit (M) SHALL be set to 1 if the first frameblock
carried in the packet contains a speech frame which is the first in a
talkspurt. For all other packets the marker bit SHALL be set to zero (M=0)."
This information bit provides a way for the receiver to better
synchronize the delay with ther sender.
This is specially useful if AMR DTX features are supported and
enabled on the sender.

Introduce a local #define to disable the real-time constraint from osmux-test.
It would make sense to remove this completely, but in case anyone may be
interested in the timing on a specific platform, I've just #defined it away.
The real-time constraint to pass or fail the test is a bad idea in terms of our
build server. Whenever the server is loaded, the tests will fail for no reason,
like here: https://gerrit.osmocom.org/474
The real time to calculate is highly dependent also on the hardware platform.
The arbitrarity of the time constraint is sort of proven by dd24cdd95f
which simply doubles the time to pass the test.

With the fan-out approach to test multi-batch added int (078d532 tests:
osmux: test multi-batch support), this doesn't need the explicit
skip as there are already gaps to be filled.
This patch adds the testsuite infrastructure and it populates it
with one test for osmux.
The osmux tests makes sure that:
* We get the same number of RTP messages in the input and the output path.
* The payload of the RTP message is reconstructed correctly.
* The reconstructed timing is correct.
