This allows for getting more exact information about each argument
especially if there are arguments that have spaces in them.
This was not implemented for darwin or for windows because they
both currently have not way of properly parsing the cmdline string.
Darwin parses the output of 'ps' which is already whitespace
segmented, and windows just has the cmdline string.
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
Add common.invoker interface to mock exec.Command. common.FakeInvoker returns
expected file if exists instead of invoke exec.Command.
Currenly, mocking is enabled only process.Pids(). I will expand to other funcs incrementally.
