dev-scheme/racket: new (masked) version 6.9 with permission from amynka.

This new ebuild comes with a lot of fixes:

  1. Dropped the unused eutils eclass.

  2. Updated the LICENSE to LGPL-3 from LGPL-2 (upstream change). I've
     also included GPL-3+ in there, because I see some plain-GPLed code
     in the source tree.

  3. Added some missing dependencies, and a comment mentioning why
     they're needed. This includes pango per bug 486016.

  4. Added a blocker on dev-tex/slatex to avoid file collisions. This
     is bug 547398, and the solution isn't entirely satisfactory, so
     I've left a comment explaining what I know.

  5. Added --disable-strip to the configure flags to avoid some QA
     warnings.

  6. Changed a few "make" commands that are used with USE=jit, to
     ensure that two executables are pax-marked before they're
     used. Along with some commands to pax-mark the installed
     binaries, this fixes bug 613634.

  7. Removed the *.desktop file DESTDIR mangling; it looks like
     whatever problem this solved has been fixed upstream.

However, this new ebuild comes with one new problem:

  1. The build randomly crashes with racketcgc segfaults. This seems
     to only happen with USE=jit. I've filed a bug upstream at
     http://bugs.racket-lang.org/query/?cmd=view&pr=15433, but even
     changing the GC doesn't appear to fix it. I get a different
     backtrace, but it's always racketcgc that segfaults. I'm not
     sure what to do about this (mask the "jit" flag?), so this
     new ebuild is committed package.masked.
