commit 38b69871ae87506c21a6b53ba418139d24305590
Author: Alexander Chemeris <Alexander.Chemeris at gmail.com>
Date:   Fri Mar 17 18:20:09 2017 -0700

    BitVector: Convert SoftVector from 0..1 to -1..+1 soft bits.
    
    This makes code simpler and will allow us send -127..127 soft bits towards
    osmo-bts instead of 0..255 bits.

    BitVector: Remove convolutional codec - we don't use it in osmo-trx.
    
    Now we have more fexibility in how we represent SoftVector, since we
    no longer depend on the particular convolutional codec implementation.

    CommonLibs: Print soft bits with less confidence to console when printing a soft vector.
    
    We use other symbols to show that these bits has less confidence:
    o and . for 0 with less confidence
    | and ' for 1 with less confidence

    Call vectorSlicer() right before packing bits for transmission to osmo-bts.
    
    vectorSlicer() converts soft-bits from -1..+1 to 0..1 while we want
    to keep SoftVector in -1..+1 mode until the last minute, because at some
    point we'll want to transmit -1..+1 to osmo-bts instead of converting it
    from 0..1 back to -1..+1 on the osmo-bts side.
    
    Plus it removes code duplication - we call it once instead of twice.

commit 132fb247b101292818afaf72f7508b594625cc25
Author: Alexander Chemeris <Alexander.Chemeris at gmail.com>

    sigProcLib: Slice SoftVector instead of signalVector for GMSK demod.
    
    This makes it similar to 8-PSK demod and also saves a bit of lines ofcode and
    should give us a tiny improvement in performance.
    
    Ideally we need to remove vector slicing at all, because in osmo-bts-trx
    we convert back to +-1.0 again (actually to +-127, but it doesn't mater).
    So we should rather transmit +-1.0 values to avoid double conversion.
