turbostat: Add option to report joules consumed per sample

Add "-J" option to report energy consumed in joules per sample.  This option
also adds the sample time to the reported values.

turbostat: servers do not support uncore power register

From the Intel Software Developer's Manual section 14.7.4,

"For server platforms, PP1 domain is not supported, but its PP0 domain
supports the MSR_PP0_PERF_STATUS interface."

When I run 'turbostat ls' I see the following error:

/dev/cpu/0/msr offset 0x641 read failed

because the server doesn't support the MSR_PP1_ENERGY_STATUS
register (0x641).  This patch implements a get_msr_nowarn()
which suppresses the above warning and then sets !RAPL_GFX.

ACPICA: Debug output: Fix a couple of small output issues.

1) Fix utcache to use the proper return macros in order to maintain
the function nesting level.

2) Enable the function nesting level for all ACPI applications instead
of just acpiexec.

Linux kernel behaviour is not affected by this patch as Linux doesn't
use ACPICA object cache mechanism currently.

ACPICA: Disassembler: Improve pathname support for emitted External() statements.

This change adds full pathname support for external names that have been
resolved internally by the inclusion of additional ACPI tables (via the
iASL -e option). Without this change, the disassembler can emit multiple
externals for the same object, or it become confused when the Scope()
operator is used on an external object.

Linux kernel behaviour is not affected as the structure changes and the
new invocations are only used by compiler and disassembler which are
not shipped in the kernel currently.

ACPICA: Back port and refine validation of the XSDT root table.

Some platforms contain an XSDT that is ill-formed or otherwise invalid
(such as containing some or all entries that are NULL pointers).
This change adds a new function to validate the XSDT before actually
using it. If the XSDT is found to be invalid, ACPICA will now fall
back to using the RSDT instead.

This feature is already in the Linux kernel.  When it is back ported to
ACPICA, code is refined to follow ACPICA coding style and this patch
is the generation of the integration.

ACPICA: Cleanup the option of forcing the use of the RSDT.

This change adds a runtime option that will force ACPICA to use the
RSDT instead of the XSDT. Although the ACPI spec requires that an XSDT
be used instead of the RSDT, the XSDT has been found to be corrupt or
ill-formed on some machines.

This option is already in the Linux kernel.  When it is back ported to
ACPICA, code is re-written to follow ACPICA coding style.  This patch
is the generation of the integration.

ACPICA: Add option to favor 32-bit FADT addresses.

This change adds an option to favor 32-bit FADT addresses when there
is a conflict between the 32-bit and 64-bit versions of the same
address. The default behavior is to use the 64-bit version in accordance
with the ACPI specification. This can now be overridden via the
AcpiGbl_Use32BitFadtAddresses flag. Lv Zheng.

Also, the "Convert FADT" and "Verify FADT" functions have been merged to
simplify the code, make it easier to understand, and make it easier to
maintain. Bob Moore.
