Fix multiple incorrect SYSCTL arguments in the kernel:

- Wrong integer type was specified.

- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.

- Logical OR where binary OR was expected.

- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.

- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.

- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.

- Updated "EXAMPLES" section in SYSCTL manual page.

Fix my previous commit. We actually should pass evaluation args in
AcpiEvaluateObject() calls, otherwise, we are not able to bring devices
back up (NULL means 0, hence always off).

Add the missing support for Asus Eee PC in acpi_asus(4).
This includes hotkeys support and sysctl variables to control camera
and card reader. These new sysctls don't have CTFLAG_ANYBODY set.

While there add entries to devd.conf related to the Eee volume keys.

Unify ACPI_DEBUG support for all OEM drivers under ACPI_OEM. Since more than
one will never be supported on the same platform, this does not hurt
debugging.

After discussions with Nate, repo copy the acpi assist drivers from
i386 to dev/acpi_support. In theory, these devices could be found
other than in i386 machines only as amd64 becomes more popular. These
drivers don't appear to do anything i386 specific, so move them to
dev/acpi_support. Move config lines to files so that those
architectures that don't support kernel modules can build them into
the kernel. At the same time, rename acpi_snc to acpi_sony to follow
the lead of all the other specialty devices.

o Change the strcmp() to a strncmp() to allow us to attach to 'E'
models of laptops, which are essentially the same as the normal
ones, as far as acpi_asus is concerned[1]

o Use the above as an excuse to reshuffle the mess I made of the
probe function when I originally wrote it.

Use the acpi_{Get,Set}Integer functions instead of rolling custom ones.
Clean up return path of each function to have a single exit point. This

Enable the led-toggling magic. Compiling files which are in the kernel into

Add the ACPI Asus extras driver. Provides support for cool ACPI-controled
