kernel: Introduce THREAD_BLOCK_TYPE_OTHER_OBJECT.

THREAD_BLOCK_TYPE_OTHER implies the "object" pointer in the
wait information is a string. But sometimes we want to pass
through objects which are not strings, for inspection in KDL.

Remove useless includes of khash.h

* These files were already converted to BOpenHashTable.
* For #9552.

* Replaced scheduler_remove_from_run_queue() by
scheduler_set_thread_priority(). Setting the thread priority was the
only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
an operation vector now, which is initialized at kernel init time.
This allows for picking the most suitable scheduler for the machine
(e.g. a non-SMP scheduler on a non-SMP machine).

Moved scheduler.cpp into new subdirectory scheduler/. Moved the
scheduler tracing and scheduler analysis code into separate source
files.
