Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement. |

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. |

Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.
There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out. |

Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.
Little bit of formatting and indentation. |
