VIRT-PHY: coding style / API usage cleanup
This is the result of my manual clean-up of the many coding style issues
found in the stumpf/virt-phy branch of OsmocomBB. Some may remain, but
it's much closer to what we're used to in the Osmocom world now.

VIRT-PHY: Remove non-overridable CFLAGS "-g -O0"
If the user wants debugging / no optimziation, they can always pass the
related CFLAGS at ./configure time, there's no nee to have them
hard-coded in the actual Makefiles.

VIRT-PHY: Configurable signal power reductions for multiple arfcns.
Model was expanded and holds now power management information consisting
of an array of received power levels for all arfcns and one for the
reduction of this signal in dbm. The reduction is configurable by
commandline by --arfcn-sig-lev-red 666,12:888,13. The signal level is
assumed to be max level (-63) if a packet from that arfcn is received
within a timeframe (also configurable via cmd -- timeout-pm 5:800 ==
<seconds>:<microseconds>). After that timeout it will be reduced to min
level (-110).

Author: Sebastian Stumpf <sebastian.stumpf87(a)googlemail.com>
Date: Sun Mar 12 14:11:40 2017 +0100
VIRT-PHY: Added option parsing.
Available options:
dl-rx-grp: mcast group messages on downlink are received from
ul-tx-grp: mcast group messages on uplink are sent to
port: port used for mcast sockets
log-mask: logging mask
l1ctl-sock: l1ctl socket path to connect to l23

VIRT-PHY: Add downlink filter for msg on dedicated channels.
Messages incoming on dedicated channel (SDCCH/8, SDCCH/4) are no longer
forwarded to l23 if their timeslot/subchannel is not fitting the ones
configured by l23 via L1CTL_DM_EST_REQ.

commit c1705d53db746551a12fe85229bda41a4d5b508a
Author: Sebastian Stumpf <sebastian.stumpf87(a)googlemail.com>
Date: Sat Mar 4 18:17:27 2017 +0100
VIRT-PHY: Fixed power management and PCS sync.
PCS flag was ignored in fbsb. Power management returned a perfect link
for all possible arfcns causing the mobile trying to sync to all these
afterwards. This took too long and PM now only returnes a good link
quality for arfcns configured as available.
Power management was also extracted to an own file.

VIRT-PHY: Fixed FACCH processing on TCH.
As TCH is not supported in GSMTAP yet, all incoming frames on the
virt-phy are forwarded as FACCH to the l23 for now.
Cleanup code in virt_prim_data and virt_prim_traffic.

VIRT-PHY: Scheduler - correct handling over hyperframe repeat.
Scheduler will no longer skip tasks that are scheduler for a framenumber
greater than the current fn because of a hyperframe repetition.

VIRT-PHY: Calculate correct scheduler fn for data- and tch-msgs on ul.
Proper calculation of the scheduled frame number and appending the jobs
with that fn to the scheduler. Thus uplink msgs are scheduled at the
(approx.) correct fn and with this fn set in the gsmtap hdr.

VIRT-PHY: Data and traffic req from l23 now use scheduler.
Msgs are not put on virt um directly in the handler like before, but are
scheduled. FN they are scheduled with not yet properly calculated.
Also, code was extracted from lactl_sap.c into own files.

VIRT-PHY: Uplink scheduler implementation.
Implemented simple scheduler depending on frame number in downlink. It
will be executed each time we receive a msg on downlink and send out all
scheduled uplink msgs with a sched_fn smaller than the one of this
received downlink msg.
Further refactored l1ctl_sap by extracting rach and fbsb logic and
putting it to own files virt_prim_fbsb.c and virt_prim_rach.c
Added simple states to the ms layer 1 model, indicating if the ms is
currently searching for bts, syncing to or camping on a bts. Downlink
will be handled differently dependent of the state.

VIRT_PHY: Improved l1ctl-to-l23 interface + gsmtap header parsing.

Proper chan_nr decoding instead of usage of dummy values for timeslot /
link_id / subslot.
Implemented missing l23 rx handler routines.

VIRT-PHY: Implemented RACH on uplink.
RACH will now be transmitted over GSMTAP virtual UM interface if L1CTL
command is received.
Minor further changes:
- Incoming messages are now only then forwarded if ms is synced to a
cell (fbsb cmd from l1ctl received).
- SDCCH/4/8 are forwarded to l23 for now as we don't use
encoding/ciphering (yet) this should not be a problem.

VIRT-PHY: Initial commit of virt-phy to work with osmo-bts virt-phy.
This patch implements a virtual physical layer replacing the air
interface. The purpose is to get rid of the hardware requirements
and be able to start testing and implementing layer 2 communication
functionality on one machine. Multicast sockets are used to enable
bidirectional communication between the BTS and the MS process.
The GSMTAP protocol designed for wireshark capturing is used to
encapsulate the payload on the virtual physical layer.
The virtual physical layer on the osmocom-bb side implements the
L1CTL interface to the layer23 apps like mobile.
* Working mcast socket communication and extraction of its
functionality.
* Basic handlers for file descriptor callbacks from incoming L1CTL
messages and extraction of that functionality to a l1ctl socket class.
* Multiplexing to different routines depending on incoming L1CTL
message type.
* Uses virt_um and osmocom_mcast_sock implementation from osmo-bts
virt-phy.
* Ecapsulation and parsing methods to and from GSMTAP messages.
* Basic handlers for file descriptor callbacks from incoming mcast
messages on the virtual um.
* Multiplexing to different channel routines based on GSMTAP header
channel type.
* Example configuration for l23 app mobile using virtual test sim.
