Peter Hutterer d557a649fd Add a public plugin system to libinput
This patch adds a new API for enabling public "plugins" in libinput, in
addition to the exisitng internal ones. The API is currently limited to
specifying which paths should be loaded and whether to load them.
Public plugins are static, they are loaded before the context is initialized
and do not update after that.

If plugins are to be loaded, libinput will then run through those paths,
look up files and pass them to (future) plugins to load the actual
files.

Our debugging tools have an --enable-plugins and
--disable-plugins option that load from the default data paths
(/etc/libinput/plugins and /usr/lib{64}/libinput/plugins) and from
the $builddir/plugins directory.

libinput

libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.

libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.

User documentation

Documentation explaining features available in libinput is available here.

This includes the FAQ and the instructions on reporting bugs.
