gr-usrptest: Initial creation

- new OOT-blocks: phase_calc_ccf hier-block, measurement_sink_f
 - new python submodules: flowgraphs, functions, rts_tests
 - new apps: usrp_phasealignment.py - cmdline example for manual testing

 OOT-Blocks:
  - phase_calc_ccf takes two complex input streams and conjugate
    multiplys them and extracts the phase from the result and converts
    it to degree scale
  - measurement_sink_f: takes a float input stream and calculates average and stddev for a
    specified number of samples. Start of a measurement is invoked by a
    call of start_run() on the block. After a couple of runs average and
    stddev can be extracted.

 Python modules:
  - flowgrahps contains reconfigurable flowgraphs for different GNU
    Radio RF test cases
  - functions contains functions which are used in different apps/RTS
    scripts
  - rts_tests contains test cases which are meant to be executed from
    the RTS system. Depends on TinyDB, labview_automation

 Apps:
  - usrp_phasealignment.py is an example how to use the underlying
    flowgraph to measure phase differences. Commandline arguments of
    uhd_app can be used and several additional arguments can/have to be
    specified. Runs a phase difference measurement --runs number of times and averages
    phase difference over --duration seconds. Between measurements USRP
    sinks are retuned to random frequencies in daughterboard range.
    Results are displayed using motherboard serial and daughterboard
    serial
