It was a mistake to call vty_init(), passing it a pointer to the
vty_app_info structure allocated on the stack, because it gets
overwritten when the calling function _vty_init() returns.

Fixes: 9feb5057 "layer23: refactor the application API concept"
Do not call grr_tx_chan_req() unconditionally from grr_rx_bcch().
Add a special (hidden, expert mode) VTY command for that.

With this set of changes we have a cleaner l23 app architecture:
* struct vty_app_info: all l23 applications must define this struct;
* struct vty_app_info: *cfg_supported() becomes a mask of L23_OPT_*;
* struct vty_app_info: explicitly set L23_OPT_* in all l23 apps;
* drop l23_app_info(), there can be only one vty_app_info per an app;
It's no more needed to obtain the vty_app_info by calling a function
and checking the returned value against NULL everywhere. This kind
of information is rather static (not dynamically composed) and needs
not to be encapsulated into functions.

Several functions and data structures in mobile app are refactored to
follow more closely the l23_app API and structures. These movements
allow starting to use already some shared infrastructure defined under
layer23/common.
This is not a full migration to l23_app, since mobile still keeps a
separate main() with a few extra code. This commit is rather a step
towards an eventual merge of mobile's main.cpp into
layer23/common/main.c
This is a preparation commit to later one adding gsmtap VTY configuration
to all l23 apps.

Use the new tundev API from libosmocore to create tun devices for each
configured (and enbled) APN.
No address nor routes are yet set on the tun devices because we still
lack GMM/SNDCP/LLC/RLCMAC layers to negotiate them.
A follow up patch will add some code to interact with the SNDCP layer.

This commit adds an initial set of VTY commands to manage APN
configuration and set up, which is used by the modem app.
The sample modem.cfg file is updated to showcase how to configure APNs.
The app doesn't do anything with them yet. A follow up patch will add
code to create tun devices for each configured APN.

This allows apps to allocate the objects as they please: simple apps can
statically allocate it at startup. Others may want to allocate them
through VTY.
Some apps may also want to dynamically start and stop layer2.
Change-Id: I32f99df76a5513eff9df5489d28d60aedf96dec3
A small layer23 framework is added which allows apps to easily share/reuse
VTY commands while giving some flexiblity to add new per-app
specific configs/cmds, since not all commands may be relevant for all
apps.
Some of the mobile app code is moved to common, and sample infra is
added to modem app.
Future commits will most probably keep moving more stuff mobile->common
and then reusing those in modem app, as found needed.

Initial VTY "boilerplate" code for modem app is already added in
this commit as a showcase what's needed by an app to have the VTY
config file read and VTY interface initialized.

This commit is a preparation towards having shared VTY infrastructure
for layer23 apps. Having 2 steps (first init(), then start()) allows
the apps easily struct allocation & initialization, and then start doing
work after VTY config has been read.

What I find weird is that the gsmmap is using files from layer23,
and vice-versa cell_log from layer23 is using files from this
utility. And somehow they are separate sub-projects.
I see no reason why gsmmap must be in its own sub-project.

This change introduces a new feature to the mobile application -
audio I/O support, which allows the user to speak right from the
host side running mobile through its ordinary mic and speakers.
The audio I/O is based on libosmogapk [1][2], which in its turn
uses the ALSA sound system for the playback and capture. This
is a new optional dependency of mobile, which is automatically
picked up if available during the build configuration. Whether
to depend on it or not can be controlled using '--with-gapk-io'.
The API offered by libosmogapk implies to use the processing chains,
which generally consist of a source block, several processing blocks,
and a sink block. The mobile app implements the following chains:
- 'pq_audio_source' (voice capture -> frame encoding),
- 'pq_audio_sink' (frame decoding -> voice playback).
both taking/storing TCH frames from/to the following two buffers:
- 'tch_fb_ul' - a buffer for to be played DL TCH frames,
- 'tch_fb_dl' - a buffer for encoded UL TCH frames.
The buffers are served by a new function gapk_io_dequeue().

Do not send voice frames to the external MNCC unconditionally.

This is needed to avoid sending voice frames to the L1PHY without
having to use MNCC specific struct gsm_data_frame.

Some L1PHY targets (e.g. Calypso based Mot C1xx phones) have built in
microphone and speaker. Some targets do not have them. Currently we
unconditionally instruct the L1PHY to handle TCH frames internally.
Make this behavior configurable via the VTY interface.

Since the mobile application is potentially able to maintain
multiple MS instances, it's better to have a possibility to
choose an MNCC (Call Control) handler per each MS separately.
This change removes the command-line option '-m', which was used
for enabling the external MNCC. Now it's possible configure the
MNCC handler for each MS via the VTY interface and settings.
The following MNCC-handlers are available:
- internal - built-in MNCC-handler (default);
- external - external MNCC-handler via UNIX-socket (e.g. LCR);
- dummy - dummy handler without CC support.

Previously the MNCC socket path was generated automatically,
using concatenation of the '/tmp/ms_mncc_' prefix and MS name.
Let's allow the user to specify this manually, keeping the same
naming generation method for default value.

This app will allow setting up a tun device to transmit/receive data
as a GPRS MS against a GSM network.
This is just the initial skeleton so that people can work on it further
in follow-up commits.
