Eliminate use of sysctl command on FreeBSD
...
In order to improve performance and help prevent crashes due to the outstanding fork crash bug:
https://github.com/golang/go/issues/15658
Replace string parsed values from the sysctl command with native reads of sysctl values using unix.SysctlRaw and unix.SysctlUint32.
This also merges OpenBSD and FreeBSD load implementations which are identical.

cpu: Implement Solaris support for Info()

cpu: Implement Solaris support for Info()
...
This commit adds Solaris(^1) support for the Info() function of package
cpu, with the exception of the L2 cache size which is not trivially
available(^2).
Support is implemented by parsing the output of `isainfo -b -v` (for the
instruction set flags), and `psr-info -p -v` for other information.
Example outputs from a range of different size VMs and Joyent containers
are included as part of the tests.
(^1): This has only been tested with Illumos in the form of SmartOS. I
believe it to be portable to other Illumos distributions but have not
tested on Oracle Solaris.
(^2): Enough support is added here to be usable for my port of
HashiCorp's Nomad to SmartOS.

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

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'

from `cpuinfo_max_freq` by 10^3 to get MHz (see
cpu-freq/user-guide.txt of the kernel documentation)

Make a public function for computing total CPU time
...
This function used to be a private part of process.go.
Since I needed that functionality however I think it's better to make it public
than for me to copy it into my own code.
As a side effect of this change, I also fixed a bug in the function where Stolen
was not part of the sum. Having the function close to the CPUTimesStat
declaration will make problems like this less likely to re-occur in the future.
