This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (946db998291c0da1b8d5428965b222a75738fcb4)
            \
             N -- N -- N (a87441c114a4425166aca776671f7d53bad95dee)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

    Transceiver52M: UHD: Check running status before stopping stream
    
    On startup errors we get a segfault if we stop and shutdown. This
    is because we try to send a stop stream command to the device before
    it has been created. Setup a check for running status before
    attempting to stop the physical device.

    Transceiver52M: Allow only channel zero to set TSC value
    
    We support one TSC value per each transceiver object. Only channel
    zero can set this value. Other channels can attempt to set the TSC
    value, but will error if the TSC does not match the existing value.
    In either case, non-zero channels do not manipulate the gloabl TSC
    setting.

    Each ARFCN channel may be independently configureted and possibly on

    The transceiver has the ability to detect bursts below the noise floor,

    Transceiver52M: Add dual channel diversity receiver option
    
    This patch add support for dual channel diversity on the receive
    path. This allows two antennas two shared antennas to be used for
    each ARFCN handling channel in the receiver. This configuration
    may improvde performance in multi-path fading environments,
    however, noise andpotential interference levels are increased due
    to the higher bandwidth used.
    
    The receive path is oversampled by a factor of four for a rate
    of 1.083333 Msps. If the receive paths are tuned within a
    maximum channel spacing (currently set at 600 kHz), then both
    ARFCN frequencies are processed by each channel of the receiver.
    Otherwise, the frequency shifted diversity path is disabled and
    standard non-diversity operation takes place.
    
    Diversity processing is handled by selecting the path with the
    higheset energy level and discarding the burst on the second
    path. Selection occurs on a burst-by-burst basis.

    Transceiver52M: Refactor receive path outer burst handling
    
    Separate the large pullRadioVector() call, which forms the central
    portion of the receive path burst processing. Break out RACH, normal
    burst, and demodulation into separate methods. This makes the burst
    handling from the FIFO read to soft bit output somewhat more
    manageable.

    Transceiver52M: Allow separate in/out vectors for delay and decimation
    
    Allow non-in-place use of the delay setting. Internally, the delay call
    creates a new vector and copies the contents back into the original.
    Instead, provide the option to return the computed output vector
    directly and remove an an extra copy in the process.

    Transceiver52M: Setup sinc() call directly with table lookup
    
    On Beagle Board the call into the sinc() function is generating a lot of
    load on the peak interpolation. Simplify the sinc() function with a
    dedicated table lookup. Eventually, this table may be removed in favour
    of using a precomputed filterbank for fractional delay determination.

    Transceiver52M: Preallocate head room for burst correlation
    
    Set a transceiver high level length value that specifies the largest
    number of complex or real filter taps that we will encounter. This
    allows preallocation of head room and prevents an extra allocation and
    copy on every incoming receive burst.

    Transceiver52M: UHD: Continue on receive and send timeouts
    
    With testing on current UHD releases, currently 003.005.xxx series,
    timeout errors on both receive and transmit are recoverable on network
    and USB based devices. Remove the fatal error conditions.

    Transceiver52M: Default to 1 sample-per-symbol low powered devices
    
    This includes ARM Cortex A8 and A15 powered device such as Beagle
    Board, Gumstix driven E100 USRP, and Arndale board. Set the reduced
    SPS value automatically for the user.
    
    For x86, if we don't support SSE3, then the architecture is
    probably ancient and not with using. Drop the sampling down anyways
    to at least make an attempt. Non floating point SIMD devices (e.g.
    Raspberry Pi) also fall in this category

    Transceiver52M: Precompute fractional delay filters
    
    Preallocate and compute a bank of fractional sample delay filters.
    The number of filters to allocate is specified by the DELAYFILTS
    preprocessor definition with a default value of 64. The filters
    themselves are sinc pulse generated with 20 taps and Blackman-harris
    windowed .

    Transceiver52M: Remove extra copy in receive drive path
    
    Currently the code allocations a signalVector and then copies
    into a radioVector. This is unnecessary because the latter is
    a derived class making the first allocation unnecessary.
    Modify the radioVector constructor to allow direct use in the
    case above.

    Transceiver52M: Dynamically allocate convolution input vectors
    
    This prevents the use of a copy constructor in the downlink
    modulator and prevents a secondary memory allocation during
    the convolution. Avoid both cases by dynamically allocating
    with preloaded head room. The latter provides enough memory
    before the first sample in the burst to cover the length
    of the filter taps.

    Transceiver52M: Add ARM NEON support
    
    Similar to the existing Intel SSE cases, add support for NEON vector
    floating point SIMD processing. In this case, use ARM assembly
    directly as the NEON intrinsics do not generate preferential code
    output.
    
    Currently support NEON vectorized convolution and floating point
    integer conversions.
