MFC r239095: Do not add handler to event handlers list until ithread
is created.

In rare event when fast and ithread interrupts share the same vector
and the fast handler was registered first, we can end up trying to
schedule the ithread that is not created yet. The kernel built with
INVARIANTS then triggers an assertion.

Change the order to create the ithread first and only then add the
handler that needs it to the interrupt event handlers list.

MFC r239169:

RFC 2289 requires all hashes be stored in little endian format before
folding to 64 bits, while SHA1 code is big endian.  Therefore, a bswap32
is required before using the value.

Without this change, the implementation does not conform to test vector
found in RFC 2289.

- Merge from NetBSD:
  When issuing a non-DMA command, make sure to set the "remaining length of
  command to be transferred via DMA" (sc_cmdlen) to zero up-front, otherwise
  we might get confused on command competition interrupt (no DMA active but
  still data left to transfer).
- Implement handling of MSG_IGN_WIDE_RESIDUE which some targets produce, as
  just rejecting these leads to a resend and disconnect loop.

MFC r238718: Quirk MS keyboard so that function keys work

  The function keys on a Microsoft Natural Egronomic Keyboard 4000 have been
  repurposed as "Help", "Undo", "Redo" etc., and a special "F Lock" key is
  required to return them to their normal purpose.

  This change enables the UQ_KBD_BOOTPROTO quirk for the MS Natural 4000
  keyboard to get the keys working again.  More extensive changes to the USB
  keyboard infrastructure would be needed to fully support the "F Lock" mode
  and the extended keys on this keyboard.
