Since the VM system has been tracking whether pages belong to internal
or external objects, pageout throttling to external pagers has simply
not been working. The reason is that, on pageout, requests for external
pages are correctly tracked, but on page release (which is used to
acknowledge the request), external pages are not marked external
any more. This is because the external bit tracks whether a page
belongs to an external object, and all pages, including external
ones, are moved to an internal object during pageout.
To solve this issue, a new "external_laundry" bit is added. It has
the same purpose as the laundry bit, but for external pagers.
* vm/vm_page.c (vm_page_seg_min_page_available): Function unused, remove.
(vm_page_seg_evict): Use vm_page_external_laundry_count instead of
vm_page_external_pagedout. Add an assertion about double paging.

vm_page_external_pagedout.
(vm_page_evict): Likewise.
* vm/vm_page.h (struct vm_page): New `external_laundry' member.
(vm_page_external_pagedout): Rename to ...
(vm_page_external_laundry_count): ... this.
* vm/vm_pageout.c: Include kern/printf.h.

(vm_pageout_setup): Use vm_page_external_laundry_count instead of
vm_page_external_pagedout. Set `external_laundry' where appropriate.
(vm_pageout): Use VM_PAGEOUT_TIMEOUT with thread_set_timeout.
Add debugging code, commented out by default.
* vm/vm_resident.c (vm_page_external_pagedout): Rename to ...
(vm_page_external_laundry_count): ... this.
(vm_page_init_template): Set `external_laundry' member to FALSE.
(vm_page_release): Rename external parameter to external_laundry.
Slightly change pageout resuming.
(vm_page_free): Rename external variable to external_laundry.

As we're about to use a new HIGHMEM segment, potentially much larger
than the existing DMA and DIRECTMAP ones, it's now compulsory to make
the pageout daemon aware of those segments.
And while we're at it, let's fix some of the defects that have been
plaguing pageout forever, such as throttling, and pageout of internal
versus external pages (this commit notably introduces a hardcoded
policy in which as many external pages are selected before considering
internal pages).
* kern/slab.c (kmem_pagefree_physmem): Update call to vm_page_release.
* vm/vm_page.c: Include <kern/counters.h> and <vm/vm_pageout.h>.

Instead of a "page considered external", which apparently takes into
account whether a page is dirty or not, redefine this property to
reliably mean "is in an external object".

kvtophys functions.

Import upstream biosmem and vm_page changes, and adjust for local
modifications.
Specifically, the biosmem module was mistakenly loading physical
segments that did not clip with the heap as completely available.
This change makes it load them as completely unavailable during
startup, and once the VM system is ready, additional pages are
loaded.

In order to increase the amount of memory available for kernel objects,
without reducing the amount of memory available for user processes,
a new allocation strategy is introduced in this change.
Instead of allocating kernel objects out of kernel virtual memory,
the slab allocator directly uses the direct mapping of physical
memory as its backend. This largely increases the kernel heap, and
removes the need for address translation updates.
In order to allow this strategy, an assumption made by the interrupt
code had to be removed. In addition, kernel stacks are now also
allocated directly from the physical allocator.

This change replaces the historical page allocator with a buddy allocator
implemented in vm/vm_page.c. This allocator allows easy contiguous allocations
and also manages memory inside segments. In a future change, these segments
will be used to service requests with special constraints, such as "usable
for 16-bits DMA" or "must be part of the direct physical mapping".

Import the macro definitions from the x15 kernel project, and replace
all similar definitions littered all over the place with it.
Importing this file will make importing code from the x15 kernel

the slab allocator from it, and we will import even more code in the
near future.

Previously, the bit field left 31 bits unused. By reducing the size
of wire_count by one bit, the size of the whole struct is reduced by
four bytes.

bits.
