This commit also introduces a new requirement to
libinput_device_destroy() - libinput_device_terminate() must be called
before libinput_device_destroy() in order to allow the user to dispatch
the events related to a terminating input devices while the device is
still valid.

Instead of having the user manage added and removed fd's as well as the
fd used for creating evdev devices, introduce a libinput object that
itself has an epoll fd.
The user no longer manages multiple fd's per libinput instance, but
instead handles one fd, dispatches libinput when data is available, then
reading events using libinput_get_event().
libinput_event's are now per libinstance, but divided into categories.
So far the only category is device events. Device events are categorized
by the presence of a non-NULL device pointer in the event.
The current API usage should look like:
struct libinput libinput = ...;
struct libinput_event *event;
if (libinput_dispatch(libinput) != 0)
return -1;
while ((event = libinput_get_event(libinput))) {
if (event->device)
process_device_event(event);
free(event);
}

Instead of having the input drivers invoke user set callbacks during
libinput_device_dispatch() and add_fd callback, let the driver queue
events that the user then reads from using libinput_device_get_event().
A typical use case would be:
struct libinput_device *device = ...;
struct libinput_event *event;
libinput_device_dispatch(device);
while ((event = libinput_device_get_event(device))) {
process_event(device, event);
free(event);
}

This commit introduces build script configuration for building a shared
library 'libinput.so' containing the evdev input device functionality
from weston.
evdev.c, evdev.h and evdev-touchpad.c are ported to not use the data
structures and API in weston and libwayland-server in order to minimize
dependencies.
The API of filter.c and filter.h are renamed to not include the
'weston_' prefix.
