zfs: Expose hostid to zfs, as in gethostid/sethostid(3).

If set to nonzero, the hostid is recorded in the metadata of a zpool,
and checked by `zpool import' when the pool has not been explicitly
exported.  After reboot, zpool import will not need `-f' to reimport
the pool.

Setting the hostid must be done explicitly through sysctl (or the
sethostid(3) library call) on all ports except acorn32, amiga,
mvme68k, newsmips, sparc, sparc64, sun2, and sun3.  So for most users
this change will have no immediate effect.  But you can obviate the
need for `zpool import -f' by adding `kern.hostid=123456789' to
/etc/sysctl.conf and importing the pool one last time with `-f'.

	external/cddl/osnet/dist/uts/common/fs/zfs/sys/zfs_context.h: revision 1.3

Use the right uid / gid for nobody:nobody like FreeBSD does.

Prevents null pointer dereferences when ZFS replaces this
illegal (according to IS_EPHEMERAL()) id with another
illegal id in operation zfs_fuid_create_cred() and
finally zfs_log_create() dereferences fuidp being NULL.

Adresses PR misc/55042 (Panic when creating a directory on a NFS served ZFS)

Mostly merge changes from HEAD upto 20200411

Sync with upstream r315983.

FreeBSD splits "zfs_context.h" into:
  "lib/libzpool/common/sys/zfs_context.h" for user space
  "uts/common/fs/zfs/sys/zfs_context.h" for kernel space

Do the same here, move and sync "sys/sys/zfs_context.h" to
"dist/lib/libzpool/common/sys/zfs_context.h" and
"dist/uts/common/fs/zfs/sys/zfs_context.h".

Change "Makefile.zfs" to search includes from "dist/lib"
before "dist/uts" so we get the right include file.

Adapt "usr.sbin/fstyp/Makefile" to get the right include file.
