clang-format taken from libinput, except for
ColumnLimit: 100
and some macro definitions (which don't all have an effect anyway...)
It's not perfect but good enough and at least consistent.

This silently ignores any bit higher than the target storage (e.g.
flag_set(some_uint32, 33)) but that's still better than silently writing
into random memory.
Add a c file for util-bits.h as well - only contains the tests but at
least that way those are picked up like all other util tests.
This is the minimum framework to support new clients, added devices and
pointer relative motion events. It's missing a bunch of checks and
verification, most of the server hooks aren't there yet, the only
implementation is a UNIX socket and the protocol is plain text (but at least
the last two makes it netcat-compatible).
Protocol is plain text for now and interaction is like this (S is server, C is client):
S: hello
C: connect myclientname
S: connected
C: add 2 4
S: accept 2
C: rel 2 -1 1
C: rel 2 5 4
Where the last two lines are: add device with id 2 and capability mask 0x4,
send a relative pointer motion event for device 2 with coordinates -1/1, then
5/4.
The implementation relies heavily on some abstraction and macros galore, see
the various util-* files. These are largely copied from libinput, with a few
parts removed and a few other parts added.
