[Pm-utils] [PATCH 01/12] Add disablehook() function to functions.in.

[Victor Lowther]

This code exists to handle using s2ram in uswsusp.  Some people seem to think
it is a cleaner and more elegant to use its video quirk-handling rather than
the stuff we have in 99video.  Oh, well, no accounting for taste. :)

I went ahead and made the mechanism generic since it costs us virtually 
nothing to do so.

This is the first step in allowing hooks to be dynamically disabled while
pm-utils is running.
