[PATCH setup 0/3] Setup replacement for incver_ifdep

[Jon Turney <jon.turney@dronecode.org.uk>]

This is an attempt at a setup feature which will allow the removal of the final 
use of 'incver_ifdep' in setup.hint, by _update-info-dir package.

See the discussions starting at around [1],[2] and following, although this 
takes a slightly different approach.

To be clear: IMHO, this functionality doesn't belong in upset or setup.

Since we now have scripts which run on every setup run, a package which requires 
another package to do some work after it is installed or uninstalled can create 
a file to act as a trigger for that to happen.

Unfortunately, it's not very practical to change to doing that for the all 
packages which contain info files, so I am suggesting this approach.

(Further note: autodep is broken in upset.  Many package which should have a 
dependency on _update-info-dir do not have one, and only 19 packages do, so this 
is not working as intended at the moment.

Yes, this means that the autodep on the cygwin package isn't working correctly, 
either.)
