Re-work Cx handling to be per-cpu and asymmetrical, fixing support on
modern dual-core systems as well.

- Parse the _CST packages for each cpu and track all the states individually,
on a per-cpu basis.

- Revert to generic FADT/P_BLK based Cx control if the _CST package
is not present on all cpus. In that case, the new driver will
still support per-cpu Cx state handling. The driver will determine the
highest Cx level that can be supported by all the cpus and configure the
available Cx state based on that.

- Fixed the case where multiple cpus in the system share the same
registers for Cx state handling. To do that, added a new flag
parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that
enable the caller to add the RF_SHAREABLE flag. This flag could also be
useful to other callers (acpi_throttle?) in the tree but this change is
not yet made.

- For Core Duo cpus, both cores seems to be taken out of C3 state when
any one of the cores need to transition out. This broke the short sleep
detection logic. It is disabled now if there is more than one cpu in
the system for now as it fixed it in my case. This quirk may need to
be re-enabled later differently.

- Added support to control cx_lowest on a per-cpu basis. There is still
a generic cx_lowest to enable changing cx_lowest for all cpus with a single
sysctl and for ease of use. Sample output for the new sysctl:

dev.cpu.0.cx_supported: C1/1 C2/1 C3/57
dev.cpu.0.cx_lowest: C3
dev.cpu.0.cx_usage: 0.00% 43.16% 56.83%
dev.cpu.1.cx_supported: C1/1 C2/1 C3/57
dev.cpu.1.cx_lowest: C3
dev.cpu.1.cx_usage: 0.00% 45.65% 54.34%
hw.acpi.cpu.cx_lowest: C3

This work was done by Stephane E. Potvin with some simple reworking by
myself. Thank you.

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64. The optimization is a trivial on recent machines.

Convert the acpi_bus_alloc_gas() and acpi_PkgGas() APIs to output the memory
type. This is needed if the resource is to be released later. The RID is
still also present, though less necessary since rman_get_rid() can be used
to obtain it from the resource.

Return a special status of "not supported" for functional fixed hardware
since this type of register should be handled by another driver.

Add support for packages as the first element of _PRW. This may allow
some machines to enable wake events for more devices although I haven't
seen a system yet that uses this form. Also, introduce acpi_GetReference()
which retrieves an object reference from various types.

Remove the device_t parameter from package routines that only used it to
print an error message. Update all callers of the package routines.

Add acpi_package.c with routines for validating packages and pulling
various data types from them. This is loosely based on the acpi_cmbat
macros (by Mike Smith) and will eventually replace them.
