132b95f01c hyperv/stor: Verify returned inquiry data before further dispatching
Windows 10 and Window 2016 will return all zero inquiry data for
non-existing slots.  If we dispatched them, then a lot of useless
(0 sized) disks would be created.  So we verify the returned inquiry
data (valid type, non-empty vendor/product/revision etc.), before
further dispatching.

Minor white space cleanup and wording fix.

3e83d3a203 hyperv/vmbus: Lookup channel through id table
Vmbus event handler will need to find the channel by its relative
id, when software interrupt for event happens.  The original lookup
searches the channel list, which is not very efficient.  We now
create a table indexed by the channel relative id to speed up
the channel lookup.

078702fc47 [flash] Teach mx25l SPI flash driver to interact with fdt_slicer and geom_flashmap
This teaches the mx25l driver (sys/dev/flash/mx25l.c) to interact with
sys/dev/fdt/fdt_slicer.c and sys/geom/geom_flashmap.c.

This allows systems with SPI flash to benefit from the possibility to define
flash 'slices' via FDT, just the same way that it's currently possible for
CFI and NAND flashes.

Tested:

* Carambola 2, AR9331 + SPI NOR flash

acae2332ed Fix panic on table/table entry delete. The panic could have happened
if more than 64 distinct values had been used.

Table value code uses internal objhash API which requires unique key
  for each object. For value code, pointer to the actual value data
  is used. The actual problem arises from the fact that 'actual' e.g.
  runtime data is stored in array and that array is auto-growing. There is
  special hook (update_tvalue() function) which is used to update the pointers
  after the change. For some reason, object 'key' was not updated.
  Fix this by adding update code to the update_tvalue().

d6a31ebe03 Prevent loader.conf load failure due to unknown console entries
When processing loader.conf if console contained an entry for an unsupported
console then cons_set would return an error refusing to set any console.

This has two side effects:

1. Forth would throw a syntax error and stop processing loader.conf at that
  point.
2. The value of console is ignored.

#1 Means other important loader.conf entries may not be processed, which is
   clearly undesirable.
#2 Means the users preference for console aren't applied even if they did
   contain valid options. Now we have support for multi boot paths from a
   single image e.g. bios and efi mode the console preference needs to deal
   with the need to set preference for more than one source.

Fix this by:
* Returning CMD_OK where possible from cons_set.
* Allowing set with at least one valid console to proceed.

waiting for the socket to become ready) was added so that they could be

changed to handle jobs in this state (JOBST_JOBQSOCK) directly removing
the need for the extra queue.  However, the per-process queue head and
