[ANNOUNCE] libinput 0.99.1

The first release candidate for libinput 1.0 is now available. 

No additions to the API, this release only contains a couple of bugfixes and
general improvements.

The most obvious fix is that natural scrolling now also works for edge
scrolling. The threshold needed to trigger scrolling on a touchpad was
reduced to 2mm in 0.21 but a bug prevented that from activating until 5mm
movement was hit. 

Touchpad scrolling now uses unaccelerated motion data. This provides better
behavior for short consecutive scroll motions and a better 1:1 mapping
between finger and content, especially with natural scrolling.

The pointer acceleration code has been cleaned up, though the focus here was
to make it easier to understand for developers. The functionality remained
largely the same aside from a few bugfixes.

1.0 will likely happen next week, I'm expecting that the only patches to be
merged for the 1.0 release will be documentation updates, fixes for build
system issues and any other technically critical bugfixes.

As usual, the git shortlog is below.
