The _THREAD_POLLING bit in thread_state was never actually a legitimate thread "state". It is a clever synchronization trick introduced to allow the thread to release the irq_lock while looping over the input event array without dropping events. Instead, make that flag a word in the "poller" struct that lives on the stack of the thread calling k_poll. The disadvantage is the 4 bytes of thread space needed. Advantages: + Cleaner API, it's now internal to poll instead of being globally visible. + The thread_state bit space is just one byte, and was almost full already. + Smaller code to write/test a full word and not a bitfield + Words are atomic, so no need for one of irq lock/unlock pairs.
