Pau Espin 134ac7e7c8 vty: Fix cmd 'no echo-interval' doing nothing
It was incorrectly implemented and in practice was a NOOP.

Pau Espin 46f04343a5 tests: in46a_test: Make coverity happy when calling in46a_from_eua
Coverity warns around that test code:
"Overrunning struct type in46_addr of 20 bytes by passing it to a
function which accesses it at byte offset 39."

That's basically because in64a_from_eua expects to be passed a 2 element
array to be filled. The second element, though, is only accessed in the
case where an IPv4v6 EUA is passed, so in the cases where the test
explicitly passes an IPv4 or IPv6 EUA it's not really an issue, hence
coverity throwing a false positive here.
Let's anyway rewrite the code to pass a 2 element array for completeness,
since it doesn't hurt and makes coverity happy.

Pau Espin ae81195418 Introduce program gtp-echo-responder
This is a small standalone program (under MIT license, hence cannot make
use of libosmocore) whose only purpose is to answer GTPC (v1 and v2)
Echo Request messages with Echo Reply ones, with information provided
from the command line.

A small python script companion is provided to easily test the program.

Pau Espin 00e0559e17 gtp: Rework parsing logic of UpdatePdpCtxResponse
The previous order of parsing lead to non-optimal information gathering
when pushing events to upper layers.

This patch rearranges parsing of packet data to always gather as much
info as possible for the benefit of the upper layer. This way it can
gather information such as the cause, which is important in the case of
"Non-existent", since user should then drop the context.

First we want to parse the recovery state, but delay cb to upper layers
until we tried to gather the pdp ctx (meaning all except that pdp ctx
should be freed).
Second, we want to parse the cause, in order to know if there's an
associated pdp ctx we can gather from TEID.
Third, once we know if we should expect a meaningul TEID, parse it.

Harald Welte 5379273ea3 vty: Inform user that static IP addresses are not supported
Currently, osmo-ggsn doesn't implement PDP contexts with static IP
addresses.  The code for specifying ranges that can be used for
static IPs was always present even from OpenGGSN days, but we never
really treated them.  Let's not raise the impression we do by
warning accordingly if the user configures them.

Previous code relied on abort() switching sigaction to SIG_FDL +
retriggering SIGABRT in case the signal handler returns, which would
then generate the coredump + terminate the process.
However, if a SIGABRT is received from somewhere else (kill -SIGABRT),
then the process would print the talloc report and continue running,
which is not desired.
