Explicit is better than implicit. Having the message type values
assigned explicitly allows rearranging messages in the middle
without affecting the message type values following them.

Remove characters 0x80 - 0xff from comments in this source file, as
they can't be parsed as UTF-8. This causes struct_endianness.py to
error on the file, git and gerrit can't display a proper diff and treat
it as binary file, etc.

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.

If the peer connected to trxcon restarts the process, read() on the unix
socket in trxcon fails, and triggers closing the conn (l1ctl_client),
which ends up freeing the struct. This all happens during read_cb() of
the l1ctl_client wqueue. If the kernel also flags WRITE event in the
same main loop iteration, the wqueue code would end up using the freed
struct again when running the write_cb.
Make sure the read_cb returns -EBADF in the code branch closing the conn
in read_cb, since it makes no sense to handle a write_cb after that.
This saves the code from accessing the potentially freed struct.

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.

Follow-up commits will add some extra checks we want to have in config.h

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.

The only caller of gsm_settings_exit() is in app_mobile so far, which is
the only app supporting/using lua scripting so far.

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.

There was no need for this check because the channel establishment
logic was at the end of handle_si13(), so I overlooked this.

Sending CHANNEL REQUEST from handle_si13() was a bad idea because
this function returns early if SI13 was received before SI1.
