Clean up hack and avoid failing if bin/ doesn't exist

It seems to work just fine and fix an error in windows 7 (it was
refused unless VLC wass run with admin rights).

Because you're supposed to

That is adding errno and live555, and disabling what currently
doesn't build

WinCE lacks errno support and thus doesn't have an errno.h header.
Since it is used like everywhere, contribs and VLC, we add a .errno
target in the contribs, that fetches a minimal errno.h that allows
everything to compile smoothly.

This is how it was done before too.

New function vlc.input.item(): returns a pointer to the current input_item

The object returned by vlc.input.item has the following members:
 - item:metas(): similar to vlc.input.metas
 - item:set_meta(name, value): change a meta. Eg: set_meta("artist", "ZZ")

Returns a table with (max.) 17 meta data about the current input

>= 0 means success (could be the new offset)
-1 = error

This bug is fixed in alsa-lib git repository. Depending on the
underlying ALSA driver, re-opening the sound card might fail if VLC
forked and executed another process. This is especially bad with
xdg-screensaver, although this could affect other -earlier- usages
of fork+exec or posix_spawn.

This fixes compilation on WinCE, where signal.h is missing
