revbump for textproc/icu

Log message:
gnuradio-*: update to 3.9.1.0

Changed
  C++14
  C11
  VOLK now “regular” dependency, not in-tree submodule
  numpy now also a CMake-checked hard dependency for Python support
  Exception Handling: throw by value, catch by reference (clang-tidy check)
  C++11: Emplace in vectors where you can; brings performance boni, but not \ 
included in clang-tidy-checks
  An exception-throwing block will now terminate the flow graph process, \ 
configurable through top_block
  gr-utils cleanup, folder restructuring
  config version checks installed CMake file will accept “at least this \ 
version” now
  PyBind11 replaces SWIG
  Full tree conversion from SWIG to Pybind11 bindings
  Doxygen now uses MathJax, full LaTeX installation no longer required
GRC
  start flowgraph in folder where it resides
gnuradio-runtime
  When calculating offsets in non-integer rate FEC, lround
  default seed for gr::random now actually as documented time-dependent
  loggers moved from gr::block to gr::basic_block
  PMT serialization
  PMT dicts no longer indistinguishable from pairs
  PMT symbol hashing no longer suffers under oddball own implementations
gr-audio
  Increased ALSA buffer nperiods
gr-blocks
  add, add_const VOLK’ized, templated
      this seems to break things in other places, even if it proves to be \ 
mathematically identical
  wavfile infrastructure: libsndfile now dependency
gr-digital
  transcendental block: default to 32 bit float complex, not double
  Linear equalizer: separate adaptive algorithm, allows for using e.g. trained \ 
sequences instead of the classical LMS, CMA
  DFE: better structure for decision history
gr-dtv
  LDPC encoder: template functions instead of #defined macros
  LDPC encoder: smaller tables through uint16_t for index tables
gr-fec
  API uint8_t, not char
gr-fft
  FFT blocks/functions templatized
gr-filter
  logging format
  rational_resampler_base -> rational_resampler
gr-uhd
  Required UHD version bumped to 3.9.7
  logging format

Deprecated
  gr-analog
    sig_source: freq port will be removed in the future
  gr-audio
    audio-sink, -source: Windows audio sink/source deprecated, the portaudio
      sink/source works even better under windows anyway
  gr-digital
    In favor of symbol_sync, deprecate:
      clock_recovery_mm
      msk_timing_recovery
      pfb_clock_sync

Added
  C++ Generation all over the place
  PyBind bindings + generator

  Validation check for QT GUI hints
  Python snippets
block header parsing tool
  block header parsing tool (GSoC 2019)

gr-analog
  sig_source: cmd port adds support for dicts, setting of frequency, amplitude,
    offset and phase parameters
gr-blocks
  selector now has control message ports
  Rotator-based freq shift convenience wrapper
  Message-to-Variable and vice versa blocks
  DC Spike removal
  IQ Swap
  Complex to interleaved char / short: scaling option
  Delay block: control message port
  Phase Shift block with message port
  wavfile_sink, _source can now deal with a lot of audio formats: uncompressed
    WAV/AIFF, µ- and A-law compressed audio, OGG/Vorbis, FLAC, even octave files
  Stream Demux, which demuxes streams according to lengths vector
  rotator: phase() getter
gr-digital
  OFDM: multiple CP lengths
