make already provides the current working directory in a variable, so make
use of it instead of forking a shell. Also replace usage of PWD by
CURDIR. PWD is provided by most shells, but not all, so this makes the
build system more robust.

Add Denverton to the group of SandyBridge and later processors,
to let the bclk be recognized as 100MHz rather than 133MHz,
then avoid the wrong value of the frequencies based on it,
including Bzy_MHz, max efficiency freuency, base frequency,
and turbo mode frequencies.

Some CPUs may not have PP0/Core domain power limit MSRs. We
should still allow its domain energy status to be used. This
patch splits PP0/Core RAPL into two separate flags for power
limit and energy status such that energy status can continue
to be reported without power limit.
Without this patch, turbostat will not be able to use the
remaining RAPL features if some PL MSRs are not present.

When i >= SLM_BCLK_FREQS, the frequency read from the slm_freq_table
is off the end of the array because msr is set to 3 rather than the
actual array index i. Set i to 3 rather than msr to fix this.

The tool uses topo.max_cpu_num to determine number of entries needed for
fd_percpu[] and irqs_per_cpu[]. For example on a system with 4 CPUs
topo.max_cpu_num is 3 so we get too small array for holding per-CPU items.
Fix this to use right number of entries, which is topo.max_cpu_num + 1.

turbostat gives valid results across suspend to idle, aka freeze,
whether invoked in interval mode, or in command mode.
Indeed, this can be used to measure suspend to idle:
turbostat echo freeze > /sys/power/state
But this does not work across suspend to ACPI S3, because the
processor counters, including the TSC, are reset on resume.
Further, when turbostat detects a problem, it does't forgive
the hardware, and interval mode will print *'s from there on out.
Instead, upon detecting counters going backwards, simply
reset and start over.
Interval mode across ACPI S3: (observe TSC going backwards)

The RAPL Joules counter is limited in capacity.
Turbostat estimates how soon it can roll-over
based on the max TDP of the processor --
which tells us the maximum increment rate.
eg.
RAPL: 2759 sec. Joule Counter Range, at 95 Watts
So if a sample duration is longer than 2759 seconds on this system,
'**' replace the decimal place in the display to indicate
that the results may be suspect.
But the display had an extra ' ' in this case, throwing off the columns.
Also, the -J "Joules" option appended an extra "time" column
to the display. While this may be useful, it printed the interval time,
which may not be the accurate time per processor. Remove this column,
which appeared only when using '-J',
as we plan to add accurate per-cpu interval times in a future commit.

cpupower_is_cpu_online(). cpu_req_cpu_exists() returned 0 on success and
-ENOSYS on failure whereas cpupower_is_cpu_online returns 1 on success.
Check for the correct return value in cpufreq-set.

ACPICA commit bbcb58f7875381d5c7f3d614bad3bc628a3f5cc6
The following build errors can be seen for MacOSX builds:

.../acmacosx.h:122:29: note: expanded from macro 'sem_destroy'
#define sem_destroy sem_close
sem_destroy() issue is caused by the wrong order of the following lines:
#define #sem_destroy sem_close
#include <semaphore.h>
