271dc496dc Switch a bunch of internal functions from int to bool
All these effectively returned bools anyway, switch the signature over to be
less ambiguous.

aa5f55149b Change to micro seconds for measuring time internally
In order to provide higher precision event time stamps, change the
internal time measuring from milliseconds to microseconds.
Microseconds are chosen because it is the most fine grained time stamp
we can get from evdev.

The API is extended with high precision getters whenever the given
information is available.

bc9f16b40e COPYING: Update boilerplate from MIT X11 to MIT Expat license
To quote Bryce Harrington from [1]:
"MIT has released software under several slightly different licenses,
including the old 'X11 License' or 'MIT License'.  Some code under this
license was in fact included in X.org's Xserver in the past.  However,
X.org now prefers the MIT Expat License as the standard (which,
confusingly, is also referred to as the 'MIT License').  See
http://cgit.freedesktop.org/xorg/xserver/tree/COPYING

When Wayland started, it was Kristian Høgsberg's intent to license it
compatibly with X.org.  "I wanted Wayland to be usable (license-wise)
whereever X was usable."  But, the text of the older X11 License was
taken for Wayland, rather than X11's current standard.  This patch
corrects this by swapping in the intended text."

libinput is a fork of weston and thus inherited the original license intent
and the license boilerplate itself.

See this thread on wayland-devel here for a discussion:

5c671e0375 evdev: Add support for POINTINGSTICK_CONST_ACCEL udev property
There is quite a wide spread in the delta events generated by trackpoints,
some generate deltas of 1-2 under normal use, while others generate deltas
from 1-20.

It is desirable to normalize trackpoint deltas just like we are normalizing
mouse deltas to 1000 dpi, so as to give different model laptops aprox.
the same trackpoint cursor speed ootb.

Recent versions of udev + hwdb set a POINTINGSTICK_CONST_ACCEL udev property
which can be used to adjust trackpoints which are too slow / too fast
ootb, this commit implements support for that property.

ee376b0b56 Revert "touchpad: parse the TOUCHPAD_RESOLUTION property"
This reverts commit 0e64837f30.

Rather than a customized touchpad property, let udev handle this and set the
absinfo struct during the normal setup procedures. No need for libinput to
have a custom workaround here.

0e64837f30 touchpad: parse the TOUCHPAD_RESOLUTION property
Not all touchpad kernel drivers supply the x/y resolution. Let the udev hwdb
fix this up where possible and read the value from it.

This is intentionally only used on touchpads, touchscreen devices without
resolution should be considered buggy and fixed in the kernel.

2ff009a45d Add a comment to clarify what the prop parameter is
prop isn't the full property line, just the value.

33ac7436a1 util: introduce ratelimit helpers
This adds "struct ratelimit" and "ratelimit_test()". It's a very simple
rate-limit helper modeled after Linux' lib/ratelimit.c by Dave Young.

This comes in handy to limit log-messages in possible busy loops etc..

3a07b03df5 Add a customizable log handler
The previous log handler wasn't actually hooked up to anything. Add a public
API for the log handler with priority filtering, defaulting to priority
'error' and stderr as output stream.

And to keep the diff down and convenience up, provide a few simple wrappers
for logging. The generic is log_msg(), but let's use log_info, log_error, etc.

ce787552bc Introduce libinput object managing all input data
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);
}
