acpi(9): Implement AcpiOsWaitEventsComplete.

Provide a primitive incrementing counter if we are call since the new
Acpi dispatcher requires us to have one when we are cold (shudder).

cast curlwp to uintptr_t before casting to ACPI_THREAD_ID, fixes i386 build

Remove also the debug-printf in case of long Stall() requests;

/*
* sleep(9) isn't safe because AcpiOsStall may be called
* with interrupt-disabled. (eg. by AcpiEnterSleepState)
* we should watch out for long stall requests.
*/

ACPICA has long printed a similar warning by itself. Moreover, this message
was never reached as the interpreter does not invoke AcpiOsStall() when a
delay longer than 255 usec is requested.

Remove the recently added warning about long Sleep() requests.

This is now in ACPICA (20100528):

Added support to limit the maximum time for the ASL Sleep()
operator. To prevent accidental deep sleeps, limit the maximum time
that Sleep() will actually sleep. Configurable, the default maximum
is two seconds. ACPICA bugzilla 854.

Print a warning if AcpiOsSleep() is called with a value larger than two
seconds. It is known that there are systems in the field that pass bogus AML
values to the Sleep() operation code, possibly requesting delays that could
be measured in days.

Discussed with jmcneill@.

XXX: While the used mstohz(9) is documented to round to one second if the
passed value is larger than 131072 ms, we may still need to force a
sensible upper limit if this warning starts to appear.

When ACPI is not present, free any resources used by the ACPICA. Also,
no need to complain (unless we're debugging) that ACPI is not present.

Switch to ACPICA 20090730, and update for API changes.

Switch to polling mode after the acpi(4) device has been suspended as
interrupts will be disabled later on and we may still need to execute
AML that tries to sleep or wait on a semaphore.
