firmware_get() will not work while resuming. Note that we can't
simply drop the FIRMWARE_UNLOAD flag, because that will result in
a firmware image that can never be unloaded by the user since the
firmware subsystem will hold a linker reference to it (it's not
clear that firmware_put() without FIRMWARE_UNLOAD ever does quite
what you'd want).
with firmware_unregister(). Previously when the last driver reference
had been dropped we would clear the list entry under the assumption
that the firmware module was about to be unloaded, but this was not
true if the firmware image had been loaded manually with kldload.
This makes it possible to manually kldload firmware images as a
workaround for drivers such as ipw that attempt to load firmware
while resuming after a suspend.

- Move sonewconn(), which creates new sockets for incoming connections on
listen sockets, so that all socket allocate code is together in
uipc_socket.c.
- Move 'maxsockets' and associated sysctls to uipc_socket.c with the
socket allocation code.
- Move kern.ipc sysctl node to uipc_socket.c, add a SYSCTL_DECL() for it
to sysctl.h and remove lots of scattered implementations in various
IPC modules.
- Sort sodealloc() after soalloc() in uipc_socket.c for dependency order
reasons. Statisticize soalloc() and sodealloc() as they are now
required only in uipc_socket.c, and are internal to the socket
implementation.
After this change, socket allocation and deallocation is entirely
centralized in one file, and uipc_socket2.c consists entirely of socket
buffer manipulation and default protocol switch functions.

* Clear the direction flag and eflags. Probably not necessary but it won't

SIGINFO has a special meaning for libpthread: when LIBPTHREAD_DEBUG

Map the device memory belonging to resources of type SYS_RES_MEMORY into
KVA upon activation so that rman_get_virtual() works as expected.
- In sbus_alloc_resource() checking whether toffs is 0 as an indication
that no applicable child range was found isn't appropriate as it's
perfectly valid for the requested SYS_RES_MEMORY resource to start at
the beginning of a child range. So check for the RMAN still being NULL
instead.
- As a minor runtime speed optimization break out of the loop where we
search for the applicable child range in sbus_alloc_resource() as soon
as it's found.
- Let sbus_setup_intr() return ENOMEM rather than 0 if it can't allocate
memory for the interrupt clearing info.
- Actually do what the comment in sbus_setup_intr() says and disable the
respective interrupt while fiddling with it.
- Remove some superfluous INTVEC() around inr, which already only contains
the interrupt vector, in sbus_setup_intr().
- While here, fix a style(9) bug in sbus_setup_intr() (don't use function
calls in initializers).
The first two changes are required for a CG6 driver.

These should not be handled by the driver.

* Add hw.acpi.resume_beep tunable and sysctl, default to 0. Beeps the PC
speaker soon after waking to diagnose whether the wakeup code is even
getting run before other drivers possibly hang the system. To stop the beep,
cause another beep (i.e. keyboard bell). Submitted by takawata@, I changed
the frequency to be lower.
* Use 4096 instead of 4 byte alignment. Might be useful although doesn't
seem to be necessary.
* Remove a useless assignment to acpi_reset_video. It was overwritten by
the default sysctl value anyway.
