host_darwin does the same filtering. Not doing this gives us some rather strange
entries that likely aren't what we want.
Before:
{"user":"reboot","terminal":"~","host":"3.10.0-327.4.5.el7.x86_64","started":1454378260}
{"user":"LOGIN","terminal":"ttyS0","host":"","started":1454378270}
{"user":"LOGIN","terminal":"tty1","host":"","started":1454378270}
{"user":"runlevel","terminal":"~","host":"3.10.0-327.4.5.el7.x86_64","started":1454378276}
{"user":"root","terminal":"pts/0","host":"vpn","started":1454404513}
After:
{"user":"root","terminal":"pts/0","host":"vpn","started":1454404513}
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.
Fixes#100
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.
