multimedia/x264: fix build on powerpc64*

1. Properly define macros to fix build.
2. Enable VSX on powerpc64le and on powerpc64 if it's available.

multimedia/*x264: Update to 0.165.3223 and transfer maintainership

* Switch to GStreamer's meson branch as it simplifies builds and is
  faster
* Transfer maintainership to multimedia
* Remove DEBUG, GPAC, OPENCL and PGO options
  By switching to Meson we can utilize the framework for debug builds
  GPAC is broken upstream
  OPENCL (lookahead) has very little advantage now that core count for
  CPUs are much higher than a decade ago and with x264's limited
  parallelization. It's also much simplier than x264's other code paths.
  PGO pulls in GCC with no to little benefit
* Add LTO and OPTIMIZED_CFLAGS options
  Available only on aarch64 and amd64, enabled by default

multimedia/libx264: add -znotext to LDFLAGS on i386, for lld

Example error:
/usr/bin/ld: error: can't create dynamic relocation R_386_PC32 against
    symbol: gettimeofday in readonly segment; recompile object files
    with -fPIC

This port links some non-PIC code, which fails with lld as it defaults
to disallowing relocations against read-only segments.  For i386 we can
just add -znotext unconditionally: for GNU BFD ld it just affirms BFD's
existing default.

	--opencl-clbin <string> Specify path of compiled OpenCL kernel cache
	--opencl-device <integer> Specify OpenCL device ordinal

multimedia/{lib}x264: Update to 0.144.2533 and major refactor

- Update to 0.144.2533 (from upstream stable branch) [1]
- Switch x264 and libx264 ports to master/slave ports respectively
- Bump PORTREVISION for dependent ports as the shared library version
  has changed.

multimedia/x264:

- Clean up and update "updating instructions" in Makefile header
- Tweak COMMENT
- Only LIB_DEPENDS on libx264 and add PLIST_FILES if this isn't the
  libx264 port.
- Allow COMMENT, USES, OPTIONS_*, CONFIGURE_ARGS to be overriden in
  libx264 port.

Our stdint.h is a symlink to sys/stdint.h so we need to teach x264 the
header guard of the sys/stdint.h file. Otherwise compiling software with the
x264.h header will generate a warning about the mismatch header guard.

multimedia/x264: General overhaul

- Split x264 into two ports: the CLI application (x264), and the library
  (libx264). This will allow x264 to use lavf and friends from ffmpeg for
  decoding and demuxing while preventing a circular dependency between the
  two: x264 can depend on ffmpeg, but ffmpeg will depend on libx264 rather
  than x264.
- Add the LAVF option to the CLI port, making the dependency on ffmpeg
  optional.
- Update to 0.142.2455.
- Amend fixes to local patches so that they can apply to the new upstream
  files.
- Provide the git revision and other version information to the build
  environment, allowing the CLI binary to display this information (like the
  Windows builds).
- Remove unsupported build options (X11_OUTPUT).
- Ensure that the library and CLI ports each have the appropriate options.
- Add notes for future contributors who wish to update the ports.
- Bump PORTREVISION for all dependent ports.
