Breno Leitao 286927a039 Improve CPU identification for POWER processors
Currently gopsutils fails to indentify the POWER processors family,
returning an almost empty Info() structure.

This patch improves the POWER identification without changing what is
available for x86.

Andreas Henriksson 9d51bfe3bb Allow clock field in /proc/cpuinfo as cpu MHz fallback value
Needed on ppc64le debian porter boxes atleast.

See #230

K.C. Wong 3dc4e52844 Handle the case when the `cpufreq` sysfs does not exist
* on virtualized host, this may happen.
* but we may have a value from parsing `/proc/cpuinfo`
* in this case, we do not return the error if we fail to extra
  a value from `cpufreq/cpuinfo_max_freq`

K.C. Wong 10a1ae2123 Standardize `Mhz` to mean maximum CPU frequency on Linux platform
* resolve #249
* in `cpu_windows.go`, `Mhz` is the value of `MaxClockSpeed`
* on Linux platform, the `Mhz` value is extracted from `/proc/cpuinfo`
  which reflects the current clock speed; treat this as the fallback
  value instead
* read from `cpufreq/cpuinfo_max_freq` under sysfs to get the
  maximum clock speed for `Mhz`, just like for Windows platform
* also fix the path to `cpu.CoreID` value; the filename is `core_id`

K.C. Wong 123a6c9b0d Addressing frequency unit discrepancies
* for Darwin, it is a minor tweak for readability: the value
  returned is in Hz, so using a variable named 'hz' makes more
  sense than 'mhz'
* for Linux, the unit is in kHz so we need to divide the value
  from `cpuinfo_max_freq` by 10^3 to get MHz (see
  cpu-freq/user-guide.txt of the kernel documentation)

Daniel Theophanes fa7f8ba4e8 cpu: CPUInfo returns one item per physical thread. Fix "Cores" to 1 on Linux.

Daniel Theophanes 0af895258e common: rename package common to internal/common. Add ENV helper funcs.
Package common wasn't used for public functions. Place it in an
internal directory to prevent other packages from using.

Remove the distributed references to "HOST_PROC" and "HOST_SYS"
consts and combine into a common function. This also helps so that
if a env var is defined with a trailing slash all will continue to
work as expected.

Daniel Theophanes 9f2e6a74cc cpu: support ARM CPUs.
ARM CPUs don't include the same fields as  x86 and amd64 CPUs in
the /proc/cpuinfo list. Pull information from the /sys/...
device tree as well as updating when a CPU is done in cpuinfo.

Jonathan Chauncey 0461c50666 chore(*): Fixes #94
Added the ability to fetch an alternative location for /proc via an
environment variable. If the env var is not set it will return /proc as
the default value.
