1.  Add README.txt with upgrade instructions as well as license info
    and governance.
2.  Add FREEBSD-Xlist to prune the distribution.
3.  Remove files & directories not used by FreeBSD.
(split) Fix typo in a comment.
(split) Fix AMRR to correctly select the initial rate.

There were two bugs:

* If the initial lowest rate didn't go through the loop at least once,
  the AMRR rate index would be the highest rate in the table
  (eg the rix mapping to MCS15) but rate would stay at the default
  value, namely 0.

  This meant that the initial rate selection would be MCS15 _but_ the
  node ni_txrate value would be MCS0.

* If the node is 11n, then break out of the loop correctly.  Beforehand,
  my initial 11n AMRR commit would immediately exit out as it would
  fail the 11n check, then it would always fall through to the non-11n
  rate which would then see if it was < 36mbit (ie, "72"), which would
  always match.  Hence, it'd always return MCS15.

Tested:

* Intel Centrino 2230 STA (local changes), STA mode
* Intel Wifi 5100, STA
(split) Move the ioapic device model from userspace into vmm.ko. This is needed for
upcoming in-kernel device emulations like the HPET.

The ioctls VM_IOAPIC_ASSERT_IRQ and VM_IOAPIC_DEASSERT_IRQ are used to
manipulate the ioapic pin state.

Change cap_rights_merge(3) and cap_rights_remove(3) to return pointer
to the destination cap_rights_t structure.

This already matches manual page.

The CAP_LINKAT, CAP_MKDIRAT, CAP_MKFIFOAT, CAP_MKNODAT, CAP_RENAMEAT,
CAP_SYMLINKAT and CAP_UNLINKAT capability rights make no sense without
the CAP_LOOKUP right, so include this rights.

- Move CAP_EXTATTR_* and CAP_ACL_* rights to index 1 to have more room
  in index 0 for the future.
- Move CAP_BINDAT and CAP_CONNECTAT rights to index 0 so we can include
  CAP_LOOKUP right in them.
- Shuffle the bits around so there are no gaps. This is last chance to do
  that as all moved rights are not used yet.
