[RFC v2] xserver: Masked valuators, mixed modes, DIDs, and ABS_MT_SLOT

[Chase Douglas]

Changes since v1:
* Many fixes found through further review
* Redo rangeToMask translation for ranged event APIs
  - No longer allocates memory except a bitmask (6 bytes) on the stack
* Add support for per-axis valuator modes
* Add support for direct valuators as an alternative to DIDs

Please see commit messages for details

Note that the I'm also tagging these pull requests as v1, v2, etc. since I'm
actively rebasing the master branch.
