Before we add handling of TCH I/O for data calls, let's rename the
existing voice related symbols and struct fields to have 'voice'
in their names.

This patch implements the signalling part for mobile originating
and mobile terminating CSD calls. The user plane interface is
to be implemented in follow-up patches.

This option must be enabled in the VTY and is disabled by default.
Calls can be joined when service is limited or normal. With that option
enabled, calls can be joined even with invalid SIM.
Talking is allowed when service is normal. With that option enabled,
talking is always allowed. It depends on the network, if it accepts the
talker.

Use TMSI only if valid in the current location area. If the MS moves to
a different location area and joins a group call before location update,
TMSI is not valid. Then use IMSI instead. If no IMSI/TSMI is available,
send mobile identity without IMSI/TMSI.

If joining a call gets rejected, the call must not be released, instead
it must return to U3 state (incoming call), because the call still
exists in the cell and it might possible to join it later.
If a call notification is gone, a new event is used in the state machine
to release incoming call.

This patch prepares for adding MT data call support:
* Move handling of the Bearer Capability IE into a function.
* Check transfer mode and coding standard in the received BCap.

Even though the function works as expected and *can* return -1,
which is first casted to unsigned and then back to signed, let's
make the code less confusing by returning -1 straightaway.

Use new_mm_state() to leave group mode. This will trigger IMSI detach
when returning to IDLE mode, if it has been delayed.

Cell selection is not supported during group receive mode. If it
happens anyway, give an error message and select correct sub-state.

These states are:
GSM48_MM_SST_NORMAL_SERVICE
GSM48_MM_SST_ATTEMPT_UPDATE
GSM48_MM_SST_LIMITED_SERVICE
GSM48_MM_SST_LOC_UPD_NEEDED
GSM48_MM_SST_PLMN_SEARCH (limited service)
GSM48_MM_SST_PLMN_SEARCH_NORMAL
If the service is limited, group/bcast calls can be joined, but uplink
access is not allowed.

The loopback mode is currently broken because the DL info header
remains present, thus becoming a bogus "part" of the speech frame.

Even if the DSP marks a traffic frame as bad (B_BFI), we still want
to deliver something to the upper layers, just like we do for FACCH.

* Reset both A_DD_0 and A_DD_1 headers, like in the case of FACCH.
* Reduce nesting, fix minor coding style issues.
* Add a FIXME for proper B_BFI checking.

The upper layers usually request either of the two configurations:
* (AUDIO_TX_MICROPHONE | AUDIO_RX_SPEAKER) - in this configuration
the phone (PHY) is both the origin and the destination of the TCH
frames. DL frames are played via the built-in speaker; UL frames
recorded using the built-in microphone.
* (AUDIO_TX_TRAFFIC_REQ | AUDIO_RX_TRAFFIC_IND) - in this case
the upper layers (host side) become the origin and the destination
of the TCH frames. The built-in speaker and microphone are
expected to be disabled.
However, when using the second configuration, one can still hear
DL TCH frames being played by the built-in speaker. The built-in
microphone does not seem to be causing any issues, but still we
definitely don't want the vocoder to interfere with the host.

Note that despite the VTY interface offers various channel type
filtering facilities, the actual filtering is not implemented.
This patch simply brings PS domain in consistency with CS domain:
the UL and DL GPRS blocks are now being sent over GSMTAP without
any filtering, just like GSM MAC blocks.
