all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Enable FFMPEG option by default. This considerably expands the file formats
aubio can handle and most users of this probably already have ffmpeg installed.

Drop python 2.7 support from a few ports

Relax hardcoded paths to fix build with Python 3.8.7

Since r558913 Python 3.8 incorporates BPO-42604 [1] which changed the
shared libs naming scheme.  This means "EXT_SUFFIX" is now derived from
SOABI and yields with Python 3.8 to ".cpython-38.so" instead of ".so".

The affected ports strip the libaries in the "post-install" target via
hardcoded path(s) and the build fails at the end because the new extension
is not expected at this place.

Remedy the issue by adding wildcards to these paths.  This should also
prepare the ports for future Python releases, which will use the new shared
libs naming scheme.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

- Allow building with python 3.x
- Add DOCS option for general documentation built by sphinx
- Add MANPAGES option build/install manpages since it requires extra deps

Update to 0.4.6

Changes:	https://aubio.org/pub/aubio-0.4.6.changelog

Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the
