commit 351fd7670649cafd5344cf6fc746f63729df97cb
Author: Alexander Chemeris <Alexander.Chemeris(a)gmail.com>
Date: Sun May 24 20:16:51 2015 -0400
sigProcLib: Fix burst start phase.
R&S CMD57 complains about the start phase of bursts, particularly it shows
-15 to -30 deg of error for the bit 0.5 position (start tail bit). This patch
makes it happy. ETSI TS 145 004 section 2.2 describes this: "Before the first
bit of the bursts as defined in 3GPP TS 45.002 enters the modulator,
the modulator has an internal state as if a modulating bit stream consisting
of consecutive ones (di = 1) had entered the differential encoder."

commit 6a2bf0d87b215860e76d1866885ae552b0ba63fe
Author: Alexander Chemeris <Alexander.Chemeris(a)gmail.com>

transceiver: Drive clock indication form the receive thread.
Receive thread receives data from the device, which is a more stable source of
clocking than the transmit side. If transmit side has a hiccup, osmo-trx doesn't
send the clock indication, and transmit side is getting completely lost in time.
With this patch we ensure that clock indication keeps coming.

transceiver: Fix out-of-bounds acces in genRandNormalBurst().
We should read gTrainingSequence starting from 0 bit index, not 61 bit index.
