(re)Introduce locking for amaps & anons. A rwlock is attached to every amap and is shared with all its anon. The same lock will be used by multiple amaps if they have anons in common. This should be enough to get the upper part of the fault handler out of the KERNEL_LOCK() which seems to bring up to 20% improvements in builds. This is based/copied/adapted from the most recent work done in NetBSD which is an evolution of the precendent simple_lock scheme. Tested by many, thanks! ok kettenis@, mvs@

Add uvm_anfree_list() to free anons as a list of pages. Use this in the amap code to free pages as a list instead of one at a time to allow for more efficient freeing. Most of the work done at elk lakes, with testing by me and mlarkin and kettenis. Speeds up a test program which zeros a big pile of memory and then exits considerably. ok kettenis@

Wait for RAM in uvm_fault when allocating uvm structures fails Only fail hard when running out of swap space also, as suggested by kettenis@ While there, let amap_add() return a success status and handle amap_add() errors in uvm_fault() similar to other out of RAM situations. These bits are needed for further amap reorganization diffs. lots of feedback and ok kettenis@

Back out the anon change. Apparently it was tested by a few, but most of us did not see it or get a chance to test it before it was commited. It broke cvs, in the ami driver, making it not succeed at seeing it's devices.

UBC was a disaster. It worked very good when it worked, but on some machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.
