kernel: Decouple sleep from suspend

Browse source 
Sleeping and suspended are now orthogonal states. That is, a thread
may be both sleeping and suspended and the two do not interact. One
repercussion of this is that suspending a thread will no longer
abort its timeout.

Threads are now created in the 'sleeping' state instead of a
'suspended' state. This dovetails nicely with the start delay that
can be given to a newly created thread--it is as though the very
first operation that a thread with a start delay is a sleep.
