Avoid string comparisons. Avoid foreach.

I kept include files to ../vlc otherwise #include syntax would break

Now, it's up to changing PKGDIR="vlc" to PKGDIR="vlc-1.0".
We just need to decide.

This Linux-specific extension fixes the close-on-exec race.

This departs from utf8_open() being a pure open() + Unicode function.
We should really always set the flag anyway, so lets factor the code.
There is still a tiny race between open() and the second fcntl() system
call, but it cannot quite be fixed within the current POSIX standards.

By the way, the correct way to clear the flag would be _after_ fork(),
but I am not aware of any such case involving utf8_open() in the
current tree.

We return true to pass killable assertion in vlc_restorecancel()

Close #2456

fix memleaks and use pl_Release.

(the bonjour part is now completely commented out)

Isn't there a gcc flag to avoid compiling that ?
 const a = value.

There is a problem with blending GREY on GREY though.
Use `Xephyr -grayscale` to test.
