there are two x extensions for working with monitors (especially
multiple): xinerama and randr. xinerama is old, feature-poor and in
general isn't used anymore compared to the randr: new, feature-rich and
widely-used. for some reason we were using both of them, so let's drop
xinerama to keep things simple, clean and small. and to be modern.
the drop was done in three steps:
* first step was to replace all the xinerama-based code with the
randr-based one and to replace or remove all the xinerama mentions;
* second step was to replace the xinerama's terminology with the
randr's one. xinerama was referring only to the word "screen", while
randr refers to multiple words and i think the word "monitor" is the
most suitable for us and, hopefully, clear both to a contributor and
to an end user;
* third step was to refactor the new randr-based code if needed and to
address related todo's (mostly about moving related functions
elsewhere).
all the steps were done well except addressing a leftover todo about
moving the win_update_monitor function to the x.c which wasn't done.
the xinerama-shadow-crop option was renamed to crop-shadow-to-monitor,
but it's previous name is still accepted, has effect and the
deprecation message is printed to preserve backwards-compatibility.
Currently picom fails at register_cm(), which is before
print_diagnostics(), so we don't see anything.
This commit makes sure we keep going when there is another compositor
already running. However, in this case we need to be careful to not take
the overlay window, otherwise a poorly implemented compositor (for
example, picom) will stop working.
Also restructured the target window initialization logic and added some
comments explaining the logic.
Fixes#333
Rational: current workaround for Composite < 0.2 doesn't work with the
GLX backend, it also doesn't handle window border properly. Plus,
Composite 0.2 came out more than a decade ago, it's safe to assume
everyone has it.

Slightly clean up header inclusion with the help of clang's module system.
It's better for files to include the things you need directly.

Also add a new config file path:
{$XDG_CONFIG_DIRS,$XDG_CONFIG_HOME}/compton/compton.conf
(For those not familiar with xdg: now compton will look for
~/.config/compton/compton.conf too)
Closes#62

It will cause compton to print out some rudimentary diagnostics.
Also small improvements of the meson.build.
