7b0b7dedd9 Entropy-pool implementation move and cleanup. 
1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release
builds on amd64 and evbarm and live testing on amd64.

3eed4a3cfa - bringing kmeminit_nkmempages back and revert pmaps that called this early 
- use nkmempages to scale the kmem_arena
- reducing diff to pre kmem/vmem change
   (NKMEMPAGES_MAX_DEFAULT will need adjusting on some archs)

8ff81a2ae9 Always include <m68k/cpu.h> (i.e. outside #if defined(_KERNEL)) 
for crash(8) as amiga and sun3.  There are _KERNEL protections in it.

Briefly tested by "build.sh -m news68k -U build".
Further possible botch will be fixed later.

319ee70223 Don't enable DB_MACHINE_COMMANDS on crash(8) (i.e. !defined(_KERNEL) case). 
No easy way to switch sun3 and sun3x at run time for now.

Briefly tested by "build.sh -U -m sun3 build".

fails (due to its size), but at least it works on maintenance kernel.

28af654232 tell the compiler that the i387 runs in double-rounding mode, so it 
doesn't need to issue memory store-read sequences to kill excess
precision. makes code smaller and faster, depending on optimization
flags
(as tests on Linux have shown, the compiler doesn't even succeed in
avoiding excess precision)

44937af7b2 amd64/Xen doesn't require special treatment for pmap_is_curpmap(), 
since cpu_load_pmap() ensures that the linear map is in place for the
kernel. This emulates normal shared kernel mappings, except for the
recursive mapping of the PDP_BASE, which will point to the per-cpu
pdir, which will be a copy of the pmap_kernel()->pm_pdir; instead of
the user pmap->pm_pdir.
