remove MALLOC_DEBUG the code has rotted, and obviously hasnt been used for ages. it is also hard to make mpsafe. if we need something like this again it would be better to do it from scratch. ok tedu@ visa@

make malloc(9) mpsafe by using a mutex instead of splvm. this is almost a straightforward change of spl ops with mutex ops, except the accounting has been shuffled around. memory is counted as used before an attempt to allocate it from uvm is made to prevent overcommitting memory. this is modelled on how pools limit allocations. the uvm bits have been eyeballed by kettenis@ who says they should be safe. visa@ found some nits which have been fixed. tested by chris@ and amit kulkarni ok kettenis@ visa@ mpi@

While splitting flags and pqflags might have been a good idea in theory to separate locking, on most modern machines this is not enough since operations on short types touch other short types that share the same word in memory. Merge pg_flags and pqflags again and now use atomic operations to change the flags. Also bump wire_count to an int and pg_version might go int as well, just for alignment. tested by many, many. ok miod@

Mechanically rename the "flags" and "version" fields in struct vm_page
to "pg_flags" and "pg_version", so that they are a bit easier to work with.
Whoever uses generic names like this for a popular struct obviously doesn't
read much code.
Most architectures compile and there are no functionality changes.

Do not use debug_malloc if it hasn't been initialized. This can happen when debug_malloc_init calls pool_init which calls malloc (because the kernel is built with POOL_DIAGNOSTIC) which in turn calls debug_malloc and debug_malloc just happens to trigger on all memory allocations. This allows us to run a kernel debugging _all_ allocations.

Pool deals fairly well with physical memory shortage, but it doesn't deal well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
