[PATCH i-g-t 1/3] configure.ac: Make udev a dependency for chamelium

[PATCH i-g-t 1/3] configure.ac: Make udev a dependency for chamelium

[Paul Kocialkowski]

Chamelium testing has a hard dependency on udev. This makes this
dependency explicit in configure instead of failing the build when it
is missing.

[PATCH i-g-t 2/3] configure.ac: Disable chamelium by default and add enable argument

[Paul Kocialkowski]

Since the chamelium is not a very usual piece of hardware and requires
pulling-in lots of specific dependencies, it makes sense to keep it
disabled by default.

An explicit --enable-chamelium argument is provided to enable it when
necessary. This also leads to more predictable results than
automatically enabling it when its dependencies are met.

Finally, whether chamelium support is enabled is printed by the
information summary at end of the configure run.

[PATCH i-g-t 3/3] README: Add information about chamelium dependencies

[Paul Kocialkowski]

This adds a list of dependencies required to build chamelium support,
so that what needs to be installed to get it going is more obvious.

As done previously in the file, the list is relevant for Debian and its
derivatives but should provide a template for other systems as well.

It appears you repeated my original mistake of switching the yes and no
parameters by accident :P. This causes passing --disable-chamelium to
result in enabling the chamelium tests instead of disabling them.

Well, the order is correct since the option is --enable-chamelium and
not --disable-chamelium anymore. However, that made me realize that it
will still enable it if --disable-chamelium is passed because I'm not
checking enableval. Will fix this in v2!
