Do not increment the parent firmware's reference count when any other
firmware image in the module is registered. Instead, do it when the
other image is itself referenced.

This allows a module with multiple firmware images to be automatically
unloaded when none of the firmware images are in use.

Update to current version of head.

seems.

Avoid scheduling firmware taskqs when cold.

This prevents a panic which occurs when a driver attempts to load
firmware at boot via firmware_get() when the firmware module has not
been preloaded. firmware_get() will enqueue a task using a struct
taskqueue allocated on the stack, and the machine will crash much
later in the firmware taskq thread when taskqs are started and the
struct taskqueue is garbage.

dynamically allocate the task structure in firmware_mountroot: when
booting from an MFS root (e.g. from an install CD) firmware_mountroot
can be called twice with the second call happening before the task
callback occurs; this results in the task structure contents being
corrupted because it was declared static.

Do image loading in a context known to have a root directory:
o create a private task queue thread that sets up root and current
directories (hooking mountroot event as needed); this is necessary
because task queue threads are parented from proc0 and it does not
have a reference to rootvnode (lost when / mounting moved to init)
o bounce image load + unload requests through the private task q so
we can load images even when the request is made from a thread that
does not have sufficient context (e.g. task q thread)
o add a check in the task q thread to fail requests before root is
mounted (just in case)

Cleanup and document the implementation of firmware(9) based on
a version that i posted earlier on the -current mailing list,
and subsequent feedback received.

The core of the change is just in sys/firmware.h and kern/subr_firmware.c,
while other files are just adaptation of the clients to the ABI change
(const-ification of some parameters and hiding of internal info,
so this is fully compatible at the binary level).

In detail:
- reduce the amount of information exported to clients in struct firmware,
and constify the pointer;

- internally, document and simplify the implementation of the various
functions, and make sure error conditions are dealt with properly.

The diffs are large, but the code is really straightforward now (i hope).

Note also that there is a subtle issue with the implementation of
firmware_register(): currently, as in the previous version, we just
store a reference to the 'imagename' argument, but we should rather
copy it because there is no guarantee that this is a static string.
I realised this while testing this code, but i prefer to fix it in
a later commit -- there is no regression with respect to the past.

Note, too, that the version in RELENG_6 has various bugs including
missing locks around the module release calls, mishandling of modules
loaded by /boot/loader, and so on, so an MFC is absolutely necessary
there. I was just postponing it until this cleanup to avoid doing
things twice.

Add a small informative printf under bootverbose to firmware_register to
track problems when loading firmware from loader.

In case we are supplied with an imagename that matches a module, but not a
firmware in that module (eventhough this is a programming error) - drop the
reference to the module again.

object returned by linker_reference_module().
