libv4l: Bump version to 1.0.1

Quite some work has been done from 0.8.3 to 1.0.1, and as a result
this commit is very intrusive. The biggest change is the move to an
autotools package.

Then, the options that enable utilities individually have been deprecated
and moved to Config.in.legacy. Instead, we introduce new option to select
either all the utilities. This change loses granularity in favor of
maintainability.

[Peter: needs host-pkgconf. Select and use argp-standalone on uClibc]
