* Rename parsePoolObjsetFile to parseLinuxPoolObjsetFile to better reflect
it's scope
* Create a new parseFreeBSDPoolObjsetStats function, to generate a list
of per pool metrics to be queried via sysctl

* Optionally fetch ARP stats via rtnetlink instead of procfs
Implement collection of ARP stats via rtnetlink to work around
shortcomings in the output of /proc/net/arp, which truncates InfiniBand
link-layer addresses.

Despite being quite hard to provoke (< 10% in my testing), the btrfs
collector would occasionally leave stale FDs relating to btrfs
mountpoints, making the filesystems unable to be unmounted.

Revert changes to node_cpu_info and add new node_cpu_frequency_hertz
metric for measuring CPU frequency from /proc/cpuinfo
Signed-off-by: John Kordich <jkordich@gmail.com>
For CPUs which don't have an available (or insertable) cpufreq driver,
the /proc/cpuinfo file can sometimes have accurate CPU core frequency
measurements. This change replaces the constant value of "1" for the
"node_cpu_info" metric with the parsed CPU MHz value from
/proc/cpuinfo for each core.

Ensure that unwanted tests are correctly excluded when various build
tags are specified, i.e. when the code that they test would be excluded
from compilation.

Drop redundant GOOS build tags at start of file if the constraint is
already specified by the filename, e.g. foo_GOOS.go or
foo_GOOS_GOARCH.go, avoiding potential confusion in future.
