games/xasteroids: render the game playable

 - switch to the usleep() based delay code
 - remove the old, no longer functional delay-loop path
 - configure the default delay to 16384 µs, which seems to be playable

games/xasteroids: fix build, cleanup

 - replace shar EXTRACT_CMD hack with custom do-extract target
   to fix the build (failed since EXTRACT_ENV was introduced)
 - define LICENSE and follow license obligations
 - clean up port Makefile, pet portlint
 - regenerate patches
 - add prototypes to source code
 - adopt this unmaintained port

Upstream has been contacted about the project license in the hope of
the project perhaps receiving a more conventional one.

Add USES=xorg USES=gl, ports categories g

Add USES=xorg and USES=gl to ports in categories starting with 'g'.
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Fix ports that confused the meaning of WRKDIR and WRKSRC.

Deprecate some ports where I can't find distfiles and upstream

-remove MD5

Convert most of remaining ports that depend on xorg-libraries to
modular xorg.

- supply corresponding USE_XORG for all imake-using ports that need it
- USE_IMAKE no longer implies USE_XLIB in absence of USE_XORG
- retire USE_X_PREFIX which is not really used anywhere after the
  above change
- a few minor nits like whitespace and SF macro
