This yields one common package to provide libfftw3 (double) and libfftw3f
(single) by default and optionally the Fortran bindings as well as
OpenMP and MPI variants, and those with long double or quad precision.
This changes all packages depending on fftwf in the same commit to minimize
the time of inconsistency. Soon, math/fftwf will disappear.

build system, 3.6 is the minimum version required.
Here is a very high level list of changes:
## Changed
### Project Scope
- C++11
- merged the wholeness of the `next` branch
- Dependency version bumps: CMake, GCC, MSVC, Swig, Boost
- New dependencies: MPIR/GMP, Qt5, gsm, codec2
- Removed dependencies: libusb, Qt4, CppUnit
- Python: Python 2 & Python 3 compatible. 3.8 will be the last Py2k-compatible
release series
- gengen was replaced by templates (if you don't know gengen, don't do any
research; save yourself that sorrow)
- Modern CMake (as far as feasible at this point)
- VOLK version updated to v2.0.0
- .clang-format file now dictates coding style
- clang-format'ed the whole tree.
- installed CMake files now tell about configuration
### gnuradio-runtime
- reworked fractional tag time handling, especially in the context of resamplers
### GRC
- C++ generation as option
- YAML instead of XML
- removed `blks2`
- much better canvas tooling
- consistent gobject usage
- ROUNDED ARROWS
### gr-qtgui
- moving from Qt4 to Qt5
### gr-utils
- `gr_modtool` now vastly improved
### gr-vocoder
- improved versatility
- removed in-tree libgsm, libcodec2, use system-wide libs
## Removed
### Project Scope
- Modules `gr-comedi`, `gr-fcd` and `gr-wxgui` are gone
### gr-comedi
- nobody could remember who used this, or for what. It has seen 0 active code
contributions in the 3.7 lifecycle
### gr-digital
- python-based `packet_encoder` and related tools: Bugs that were sporadic and
never fixed, so after long deprecation, we're removing it
### gr-fcd
- since it's currently untestable by the CI, it's being removed, as there was no
code contributions. Generally, we strive to include all batteries with GNU
Radio. Re-integration within a more general SDR interface would be desirable.
### gr-utils
- removed PyQwt (dead) based tools
### gr-wxgui
- Unmaintained, breaks on increasingly many systems, always was slower than
Qtgui. We've been starting to tell people to migrate to Qt since at
least 2015. Now, we're finally removing it.
Note that the previous gnuradio-core package conflicts with math/volk.
In order to update you must delete the old gnuradio-core package so
that math/volk can first be installed.
pkglint --only "https instead of http" -r -F
With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.
This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.
## [3.7.13.4] - 2018-07-15
### Fixed
#### Project Scope
- Fix Boost 1.67 linking issue
#### gnuradio-runtime
- Logging: fixed issues where messages weren't properly written to
stdout/stderr due to incorrect strings
#### gr-analog
- `fmdet_cf`'s derivative coefficients were wrong.
#### gr-blocks
- `skiphead` used to incorrectly handle tags, now properly shifts
#### gr-digital
- `qa_packet_format`: Unit test used to potentially lock up due to
incorrect condit ionals
- `clock_recovery_cc`, `crc32_bb`: Accessing the `[0]` element of an
empty vector is UB, even if you don't use the result afterwards.
#### gr-fec
- `polar_encoder`/`_common`: Fixed multiple out-of-bound accesses due
to insufficient vector length checks
#### gr-filter
- `fft_filter`, `filter_delay`: Accessing the `[0]` element of an
empty vector is UB, even if you don't use the result afterwards.
## [3.7.13.3] - 2018-06-13
### Fixed
#### Project Scope
- For non-C++11 compilers, the new cstdint include doesn't work out; conditionalized it.
## [3.7.13.2] - 2018-05-31
### Fixed
#### Project Scope
- Actually bumped version in CMakeLists.txt to 3.7.13.2; the 3.7.13.1 tag was tagged off-branch; maintainer failure to simultaneously push a commit that raises the internal version number to 3.7.14.0: this had to be reverted ASAP.
## [3.7.13.1] - 2018-05-31
### Fixed
#### Project Scope
- Actually bumped version in CMakeLists.txt
## [3.7.13.0] - 2018-05-31
### Fixed
#### Project Scope
- `boost::posix_time::[milli]second` takes integer numbers, and we now at least cast the floats to integers, as Boost 1.67 forced us to realize we're (incorrectly) using floating point her
- CMake: using regex to match compiler against "Clang" now enables correct build on OS X
#### GRC
- Fixed GRC bug which broke WX and Qt (by altering the template code), in multiple (less than awesome) steps
#### gr-blocks
- `float_array_to_int`: int32 limits were wrongly hardcoded.
- Fixed the undefined behaviour happening in `float_to_complex` when accessing the second input_items element in the single-input case
## [3.7.12.0] - 2018-04-01
### Software Engineering
- Changed Changelog format
- Introducing Semantic Versioning
- Change of development model: Rather than merging bugfixes to maint, merging maint to master, and next, if applicable, we'll be moving forward more in a typical management model: Development happens on master, and bugfixes are cherrypicked onto the maint-${RELEASE} branch. More info: http://lists.gnu.org/archive/html/discuss-gnuradio/2018-02/msg00133.html
- First attempt at having a .clang-format file to improve code contribution style quality. This is Work In Progress.
### Fixed
#### Project Scope
- Buildability on systems where custom CMake command would try to find "" (empty string) as executable
- Buildable with C++11 compilers (though deprecation warning-rich, due to `unique_ptr`)
- several previously improperly handled include directories now actually included in individual lib/CMakeLists
- Unit test/QA now parallelizable

- Doxygen build now reproducible
#### GRC
- Dialogs' parent windows
- Embedded Python Blocks now work in hierarchical GRC flow graphs
#### gnuradio-runtime
- `random.h`: Uniform integer Generation depended on Boost version > min version
- `random.h`: time-dependency when seeding with `0` replaced with actual standard seed
- block startup now synchronized via barrier
- New tag propagation policy "custom" for own implementation
- `get_tags_in_range` used `v.resize(0)` to clear vectors, which lead to unnecessary memory reallocations
- `logger_ptr` now always a pointer, no matter whether logging is enabled; fixes heap corruption bug
- `buffer[_reader]_sptr` superfluous grab/release performance bug
- BSD threading and shared mem compatibility
- PMT: `equal()` comparison
#### gr-utils
- Sorted files in `gr_modtool` makexml processing, leading to improved reproducibility of builds
#### gr-audio
- OS X: memcpy bug
- OS X: debug mode
- Non-Linux ALSA compatibibilty
#### gr-analog
- `fmdet_cf` now has GRC file
- `fastnoise_source`: non-threadsafe `libc` `rand()` replaced by XOROSHIRO128+
#### gr-blocks
- `simple_copy` Ctrlport example
- Metadata sink/source not closing file on `close()`
- `multiply_matrix` formerly used "magic int" value where its API expected enum (and that int wasn't covered)

- `chunks_to_symbols`: mutex-guard LUT against modification during use
- MSVC compatibility throug `and` -> `&&` etc
- `crc32_bb`: handle unpacked bytes correctly
- `ofdm_carrier_allocator`: catching wrong allocations instead of crashing
#### gr-dtv

- DVB-T2: Removed L1 post scrambling in spec v1.1.1 mode
#### gr-fcd
- Building on non-Linux systems
- Extended symbol bug in Reed-Solomon encoder

### Deprecated
#### gnuradio-runtime
- `gr::sys_pri`

making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.
