This adds tests for the gprs_ns_sendmsg() function. For this it
merges back functions from the gbproxy test.

Under special circumstances (see below) receiving a NS-RESET leads to
duplicated NS-VC entries.
This happens when the source port of a NS-VC changes to a new one
that has already been used by another NS-VC.
This patch changes gprs_ns_rx_reset() to check for this case and to
use the existing NS-VC object. The NS-VC object that was associated
with the source address before is detached from this source but kept
in the NS-VC list so that it can be reattached when a correspondent
NS-RESET is received later on. Meanwhile it will have a cleared link
layer address which will not match a real link info.
A new counter NS_CTR_REPLACED is incremented each time when the NS-VC
object is replacing another one. A new signal S_NS_REPLACED is added
which gets dispatched in this case, too.
Another new counter NS_CTR_NSEI_CHG is incremented each time when the
NSEI of a NS-VC object (with fixed NSVCI) changes.

Adds the functions gprs_ns_ll_copy() and gprs_ns_ll_clear(). Renames
gprs_ns_format_peer() to gprs_ns_ll_str(). All of these functions
uniformly access the link layer part within the NS-VC objects.

Register an osmo signal handler to print a short notice about every
SS_L_NS signal that is generated while processing the tests.

Currently when a NS-RESET is recevied over a link that has not yet
been associated with a NS-VC, the NSEI is used to find an existing
NS-VC. If one is found, the reset procedure is initiated.
This behaviour is not conformant with 3GPP TS 08.16 (see chapter
4.2.3) which allows to use several NS-VC between two endpoints in
parallel.
The patch changes the implementation to use the NSVCI instead
of the NSEI to search for an existing NS-VC object.

According to 3GPP TS 08.16, 7.3 "Reset procedure" the entity
receiving a NS-RESET PDU responds with a NS-RESET-ACK and 'then'
starts the test procedure which essentially means, that a NS-ALIVE
gets sent and a timer is started.
Currently the NS-ALIVE is sent before the NS-RESET-ACK.
This patch fixes the implementation by reversing the order in which
these messages are sent.

This tests the connection establishment by directly calling
gprs_ns_rcvmsg() and printing the resulting messages and the
NS-VC list.

* Disable color and printing the filename of the stderr log target,
update the results
* Add the .ok, .err and .sh files to the extra_dist
* Execute the shell script from the source directory

this ensures that we can talloc the flow-control queue entries
as siblings off the bvc_ctx.

we use a smalle shell script to iterate over multiple tests
