* Lowered CPU requirements to allow for use on Android/Netbook devices:
- Added modes 125FL and 250FL with constraint length 13 FEC
- Adjusted maximum traceback memory for viterbi decoder
- Set traceback to an optimally-high value in viterbi.cxx constructor
- 8PSK - 500F 1000F & 1200F now use only 1 viterbi decoder without voting

L - long, 64 bit
* Add function modem->rx_flush() to flush receiver buffer to the

Merger of all work submitted by Remi which was based on
3.13BY. Merge accomplished by reducing mulitple commits
to a single and then cherry-picking that commit to the
master branch. No merge conflicts were experienced.
Modified fl_digi.cxx / wefax items to comply with post
3.13BY changes.
Added Contestia modem with Rx/Tx support of RSID. This mode is
not suitable for use with flarq, flwrap or flics. It is very
suitable for contesting or conversational QSOs.
The qsy() function will now change the rig frequency when it notices
that the modem is permanently frequency-locked (e.g., MT-63).
* Remove modem_frequency argument and associated code from the various
rig control set_qsy functions, this is now done by qsy().
* Make modem::set_freq() virtual and override it in mt63 in order to
better prevent frequency changes.
* Use qsy() in the RSID decoder and notifier "Go to freq" callback.
Add menus to select
* modes that will be switched to on RSID reception
* modes for which to transmit RSID / VideoID / CWID
The defaults are:
* Receive RSID: all modes
* Transmit RSID & VideoID: all except CW, PSK31, RTTY
* CWID: all except CW
Also add option to choose which modes are shown in the main OpMode
menu.
* Reorganise RSID data declarations
* Synchronise with F6CTE's RSID list
* Decode and transmit RSID for Olivia 8/1000 and 8/250
* Print message when decoding RSID for unimplemented modes
* Added new modem types PSK-125R, PSK-250R, PSK-500R,
which use the following for additional noise and phase
multipath immunity:
. convolutional coding
. bit interleaving
. soft decoding
* Added modem type PSK63F, compatible with MultiPsk PSK63FEC
* Added RSID codes for PSKR and PSK63F
* Changed naming convention of MODEM_BPSK31 to MODEM_PSK31 to be
consistent with other PSK baud rates
* Change Sound*::Read methods to float
* Enable RSID upsampling for 8 KHz modems
* Add main.{get,set,toggle}_rsid XML-RPC methods
* Add option to disable RSID decoding on reception
* RSID may be enabled during transmit or tune
