mesa dependency is already pulled by default since 'X' and 'opengl' USE
flags are enabled by default. All current mesa versions in tree already
have 'egl' USE enabled by default, so no extra adjustment is needed for
users.
Thus enabling it by default will give users a wider range of options.

VAAPI + EGL combo requires Thread Local Storage C++11 feature or
GNU __thread extension. Add the corresponding check for sanity.

VAAPI in mpv is now available for Wayland and for EGL and GLX on X11 as
opposed to GLX only before. A newer libva version is required, though.
Package-Manager: portage-2.2.24
Currently 'opengl' USE stands for 'anything that draws using OpenGL
API', and 'egl' USE stands for 'EGL for X11'. Notice these are not
complementary.
Thus, for example, on Wayland one should use 'mpv[wayland,opengl,-egl]',
which is a bit counterintuitive, since Wayland (compositor) uses EGL
only. Also one cannot disable GLX support, but leave EGL on X11, because
of USE flags interdependencies.
Both X11 and Wayland use OpenGL API to do drawing, but historically the
first one was native OpenGL in X11 aka GLX and later came EGL in X11 and
Wayland. However, now there is a tendency to prefer EGL to not bind
oneself to X11.
There is no global 'egl' USE atm, but the logic of local 'egl' USEs
across the tree is 'not bind oneself to GLX'. On Linux there is no need
to repeat that drawing is done using OpenGL API even when EGL comes to
play.
Taking all of the above into account more sane and expected meaning
should be given to 'opengl' and 'egl' USE flags.
After this change 'opengl' USE stands for 'OpenGL in X11 aka GLX' and
'egl' USE stands for 'any EGL-based output'. Notice these are now
complementary.

mpv uses libass to render subtitles and enca to detect subtitle
encoding. For mpv to support enca, mpv does not need to have
libass[enca]. This helps to avoid problems with >=libass-0.13.0,
which dropped 'enca' USE.
Also enable harfbuzz USE to support subtitles for complex languages.
See [0] as a reference for both of the above.

The first libdvdread-4.x version that entered the tree was 4.1.3, so
from the Portage point of view this is ditto. However, mpv configure
script requires libdvdread '>=4.1.0'. Unless someone wants to include
this lengthy explanation why these two versions mismatch in the ebuild,
adjust libdvdread version in dependency.

enca and libguess are used only for subtitles charset discovery.
Minor wording improvements for vf-dlopen and jpeg USE flags.

Similar idea was submitted by Vindex17 in PR #318.
Though libsdl2 is listed under audio outputs in configure script,
it actually handles both audio and video outputs. Thus video and sound
USE flags should be enabled for libsdl2. We also want X or wayland USE
flag enabled for libsdl2, so mpv can create a window to render in.

mpv has a small, but working test suite. It requires dev-util/cmocka,
which is missing ~alpha keyword atm. Thus a package USE mask is needed.
See bug 569558 for dev-util/cmocka KEYWORDREQ.

This was originally submitted by Vindex17 in PR #318.
Local cdio USE has the same meaning for mpv as global cdda USE. It looks
like it was copied from mplayer ebuild where it made sense, because
mplayer could support both cdparanoia and cdio-paranoia at the time. On
the other hand, current mpv only supports cdio-paranoia.

This way user is also informed after the build that he may lose some
functionality with libav.

This helps to avoid confusion that waf sources are the only ones being
fetched.
Suggested by mgorny in PR #511.
Also use a shorter fetch URL for waf sources.
