Tagging HelenOS 0.3.0.

/trunk/
code cleanup (mostly signed/unsigned)
allow extra compiler warnings

/trunk/kernel/
remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)

First fixes for suncc support.
It is going to be a long way...

Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();
Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!
Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.

Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.
Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.

When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.
Formating and indentation fixes.
