The definitions of va_alist, va_dcl belong elsewhere.

a0d9bd5bb2 The hack-ish tricks to make the ANSI-style va_start macro work in 
non-ANSI mode were not quite complete.  This makes non-ANSI work.
Perhaps it would be better to eliminate this hack altogether...

2fc2b98d83 make pageout sleep on vm_pages_needed rather than lbolt. this stops 
pathological behaviour (freezes) when running short of free pages.  see
PR#2755 for a more detailed explanation (from jonathan).

thanks to john dyson for the first cut of this change.

62034405e6 allow kmem_malloc to return NULL if canwait is set and there's no map space 
left, rather than panic()ing.  This allows callers to set their own policy
for how to handle the shortage.  Add a few comments.

d0fd3d7e62 Don't declare pmap_page_index for now. It will break the arm port. 
This clearly needs to be fixed. I would like to declare it:

    __pure u_int     pmap_page_index __P((vm_offset_t));

but at least the arm port wants it signed [since it tests for -1 all over
the place]. Can we have this fixed please?

801712f01a Extend use of vm_object_prefer() to vm_allocate_with_pager(). 
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.

Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.
