40cf6f3659 Remove uarea swap-out functionality:
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

de3d6f78cf Fix a bug where on MP systems, pool_cache_invalidate(9) could be called
early during boot, just after CPUs are attached but before they are marked
as running.

This will result in a list of CPUs without the SPCF_RUNNING flag set, and
will trigger the 'KASSERT(xc_tailp < xc_headp)' in xc_lowpri() as no cross
call is issued.

Bug reported and patch tested by tron@.

65dd100015 Check for zero length read here - and return zero.
Most times we've come through spec_read() which has already done the test,
but not always (eg pty with ptsfs mounted).
Without this there is a simple local-user panic in ureadc().

4c9fcb77c3 - Add usermount_common_policy() that implements some common (everything
but access control) user mounting policies: enforced MNT_NOSUID and
  MNT_NODEV, no MNT_EXPORT, MNT_EXEC propagation. This can be useful for
  secmodels that are interested in simply adding finer grained user mount
  support.

- Add a mount subsystem listener for KAUTH_REQ_SYSTEM_MOUNT_GET.

b2f3768346 - Move sched_listener and co. from kern_synch.c to sys_sched.c, where it
really belongs (suggested by rmind@),

- Rename sched_init() to synch_init(), and introduce a new sched_init()
  in sys_sched.c where we (a) initialize the sysctl node (no more
  link-set) and (b) listen on the process scope with sched_listener.
