Convert the dtrace(1) man page to mdoc and fix up some aspects of it that
don't make sense on FreeBSD. In particular,

- remove the ATTRIBUTES section,
- remove references to the Solaris Dynamic Tracing Guide, except in the
  SEE ALSO section,
- update the description of the -A option for FreeBSD's implementation,
- remove references to Solaris-specific programs and configuration files,
  and replace them with FreeBSD equivalents where possible.

The content has not changed aside from this.

Add support for "vnet jname" argument in ifconfig_IF.  The vnet keyword
is ignored except for "rc.d/netif vnet{up,down} ifn" because a jail is
usually created after interface initialization on boot time.

"rc.d/netif vnetup ifn" moves ifn into the specified jail.  It is
designed to be used in other scripts like rc.d/jail, not automatically
invoked during the interface initialization.

- Update rc.d/jail to use a jail(8) configuration file instead of
  command line options.  The "jail_<jname>_*" rc.conf(5) variables for
  per-jail configuration are automatically converted to
  /var/run/jail.<jname>.conf before the jail(8) utility is invoked.
  This is transparently backward compatible.

- Fix a minor bug in jail(8) which prevented it from returning false
  when jail -r failed.

MFV r255257: 4082 zfs receive gets EFBIG from dmu_tx_hold_free()

  illumos change 14172:be36a38bac3d:
  illumos ZFS issues:
    4082 zfs receive gets EFBIG from dmu_tx_hold_free()

Please note that this change is slightly different from r255257, because
it is merged out of order with other (larger) upstream changes.

Fix for When more than one NIC is present.

The device name was incorrect due to a specific function we ported
from the Linux driver that is not FBSD compatible.  This resulted
with a false sysctl registration and some more problematic issues.

The patch basically revokes it all together.

Sanitize the %eflags returned by BIOS routines.  Some BIOS routines enter
protected mode and may leave protected-mode-specific flags like PSL_NT set
when they return to real mode.  This can cause a fault when BTX re-enters
protected mode after the BIOS mode returns.

Fix the "am I a net80211 vap" check for bpf listeners.

I changed it to use if_transmit a while ago but apparently with monitor
mode the if_transmit method is overridden.

This is (mostly) a workaround until a more permanent solution can be
found.
