Remove unreal allocators, unconditionally use subr_{kmem,pool}.

Will, with other work, allow to tighten the memory allocation hypercall
specification to page-granularity allocations in the future.

* treat kern_malloc.c as an unreal allocator (it's so lightweight)
* get rid of the rumpuser_realloc() hypercall
* pass size to rumpuser_free()

Use kern_malloc.c instead of the relegated allocators in memalloc.c.
Previously this didn't make sense due to the use of kmem_map, but the
new malloc is more dynamic and puts sense into using it.

(previously it was just missing in that case).

Record wchan to unreal pool_init() to avoid memory leak warning.

Now that pool_cache_invalidate() is synchronous and can handle per-CPU
caches, merge together pool_drain_start() and pool_drain_end() into

bool pool_drain(struct pool **ppp);

"bool" value indicates whether reclaiming was fully done (true) or not (false)
"ppp" will contain a pointer to the pool that was drained (optional).

Remove everything to do with 'struct malloc_type' and the malloc link_set.
To make code in 'external' (etc) still compile, MALLOC_DECLARE() still
  has to generate something of type 'struct malloc_type *', with
  normal optimisation gcc generates a compile-time 0.
MALLOC_DEFINE() and friends have no effect.
Fix one or two places where the code would no longer compile.

Remove the unused 'struct malloc_type' args to kern_malloc/realloc/free
The M_xxx arg is left on the calls to malloc() and free(),
  maybe they could be converted to an enumeration and just saved in
  the malloc header (for deep diag use).
Remove the malloc_type from mbuf extension.
Fixes rump build as well.

Emulate malloc(9) a little better by panicking if a should-not-fail
allocation fails.  We could invoke the pagedaemon here, but since
malloc(9) is panicky when it runs out of kmem_map, let's do the
"same".

Make it possible to define an upper limit for memory consumed by
the rump kernel by specifying RUMP_MEMLIMIT.  In case allocation
over that limit is attempted, essentially pool reclaim and uvm_wait()
is done.  The default is to allow to allocate as much as the host
will give.

XXX: uvm_km_alloc and malloc(9) do not currently conform.  the
former is easy, the latter requires kern_malloc.c (rump malloc is
currently directly relegated to host malloc).

Implement a sort-of pagedaemon: adjust all memory allocators to go
through an in-rumpkernel hypermemory allocator which knows it should
kick the pagedaemon and block in case ``waitok'' memory allocation
fails.

This allows us to recover from some out-of-memory situations.
Realworld'istically speaking (as opposed to whatever "should be"
theory), these OOM situations will happen extremely rarely if ever
when our hypervisor is a regular process.  Speculatively, this
should be useful for other types of hosts.

issues remaining:
 * the hypervisor does not know how to reclaim kernel memory (and
   for the reason I stated above, I'm not sure if it makes sense
   to teach the current implementation about that)
 * vfs memory (buffers, vm object pages etc.) is not reclaimed

Don't pass "canfail" down to rumpuser_malloc -- there's quite little
we can do with that info way down there.  Instead, pass alignment.
Implement rumpuser_malloc() with posix_memalign().

Use subr_percpu.c instead of homegrown implementation.  ...except
when using malloc(3)-relegated allocators (happens in production
e.g. on Linux), since subr_percpu.c uses vmem and i don't want to
reimplement vmem.

Now that Makefile.rump was changed and everything gets built in
update builds too, flip the allocator define to prefer the kernel
pool/kmem instead of malloc(3).  Use malloc(3) only if
RUMP_USE_UNREAL_ALLOCATORS is defined.
