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.

The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.
Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.

Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.
Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.
Lots of coding style changes.

Take the possible difference between kernel and physical address into account in TSB and userspace window buffer
allocation and deallocation code.

SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.

sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).

- Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.
- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.
- More TSB work on the sparc64 front.

C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
