Alexander Couzens 2ab489641b gtphub: rename sgsn's oww osmo_sockaddr into sgsn_sockaddr
The osmo_ prefix should be only used for official struct/apis of libosmocore.
This commit was done via `sed -i 's/osmo_sockaddr/sgsn_sockaddr/g'`.

In prepartion of introducing a different api of osmo_sockaddr to
libosmocore.

Oliver Smith 5997357c69 osmoappdesc.py, tests: switch to python 3
Make build and external tests work with python3, so we can drop
the python2 dependency.

This should be merged shortly after osmo-python-tests was migrated to
python3, and the jenkins build slaves were (automatically) updated to
have the new osmo-python-tests installed.

Pau Espin 31c4657c97 Implement GMM State using osmocom FSM
State machine inspired in the one from TS 24.008 4.1.3.3.1. Some state
transitions are inroduced in the code but are still commented out since
we lack some functionalitites or improvements in the code to handle
different scenarios.

Most of the logic is still outside of the FSM, but at least now the
states are handled in a sane way triggered by events.

Alexander Couzens 39cbecd273 gprs/gprs_gmm: implement T3314. Timeout to reset MM state READY->STANDBY
When a MS MM state is READY its exact location is known (PCU).
On Gb, T3314 (aka TS 23.060 "READY timer") sets the MM state from
READY to STANDBY, where only the RA is known.

Introduce a second set of timer variables, because state timer
can run while another packet state timer is timing out.

Stefan Sperling c5721545c6 use enums consistently instead of falling back to int
The two existing enums defined in gprs_sndcp_xid.h, for protocol
and data compression algorithm numbers respectively, were assigned
to 'int' variables when their values were copied to other structures.

This prevented the compiler from checking the enum value coverage
during switch statements and also tripped up Coverity scans looking
for enum value mismatch problems.

So instead of copying enums to ints, make use of the enums throughout.
Structures which can contain values from both enums now use a union
of both, forcing us to be very explicit about which set of values
we are dealing with.

Knowing which security context was established will be necessary for OS#3224,

probably not correct at this stage.

selects the highest version of python, no matter if major version is
different, which means if both python2 and 3 are available, 3 will be
chosen an PYTHON will point to "/.../python" which is python3. Apparently,
the macro cannot be easily used to pick highest python2 version.

As {vty,ctrl}_test_runner.py require python2 and are incompatible with
python3, let's instead rely on the system having a "python2" binary
available, which is the case in most distros.
