Import ACPICA 20090521.

Chase ACPICA API changes (for kernel and boot loader).

GPE lock may recurse on resume path.

- Use '*h' instead of 'struct acpi_spinlock' for sizeof[1].
- Add a missing 'else' for 'if'[2].

Correct ACPI semaphore function parameters.

Free the handle, not the lock. Pointy hat to me.

Correct ACPI spinlock function parameters and use known ACPI spinlock names.

Use a unique name for each mutex now that acpi-ca is creating more than

Use a unique name for each mutex now that acpi-ca is creating more than
one (hardware & global lock). This should address witness complaints that
a duplicate mutex is being acquired. Be sure to free the mutex to fix a
potential memory leak.

Make tv_sec a time_t on all platforms but alpha. Brings us more in line with
POSIX. This also makes the struct correct we ever implement an i386-time64

Style cleanups, use M_ZERO instead of bzero, unify the !semaphore and
semaphore return paths.

Make debug.acpi.level and debug.acpi.layer sysctls that can be set with
the strings found in acpi(4). Also make acpi_ca_version a string so it
is more readable.
