Thomas Gleixner 22f011be7a hrtimer: Convert state and properties to boolean
All 'u8' flags are true booleans, so make it entirely clear that these can
only contain true or false.

This is especially true for hrtimer::state, which has a historical leftover
of using the state with bitwise operations. That was used in the early
hrtimer implementation with several bits, but then converted to a boolean
state. But that conversion missed to replace the bit OR and bit check
operations all over the place, which creates suboptimal code. As of today
'state' is a misnomer because it's only purpose is to reflect whether the
timer is enqueued into the RB-tree or not. Rename it to 'is_queued' and
make all operations on it boolean.

This reduces text size from 8926 to 8732 bytes.
