Implement hashed old unix style sleep( var address )/wakeup( var address ) mutexes

[GoogleCodeExporter]

Those can be used for object land stuff as well for
usual mutex uses spinlick and can't be kept in paged
memory (page fault will attempt to put process with spinlock asleep,
which is forbidden)

If mutex body is outside of it's guarded struct, its ok 
to use it in any circumstance.
