[arm-allstar] RTCM txctcss values between Acid and Rpi2-V1

[David McGough]

Hi Ross,

How old is your ACID install?  The reason I ask is that there was a bug
fix in the channels/xprm/xprm.c file that was committed to the AllStar SVN
server back in January, 2015.  This bug fix greatly improved the receive
audio S/N ratio, but, as a side effect, it altered the audio level
adjustment somewhat.  This change only impacted the chan_voter and
chan_usbradio---not chan_simpleusb.

The RPi2 V1.0 release does run exactly the same code as was found in the 
AllStar SVN, as of the V1.0 release date (which was April 10, 2015).
