Add GravisZro's initial work on a udev-to-vdev rule converter (Issue
Include both the ISC license and GPLv3+, in preparation for
dual-licensing.
Better pidlist matching logic: propagate the vdev environment variables
to the pid-listing command.
Add the ability to select the device node's path before creating it (as
part of an action).  Update the action logic to use the new subprocess
method in util.cpp
Better subprocess routine--allow us to set environment variables
directly.
Initialize the vdev back-end early, so we can fail fast if we fail to
parse an action.
Only unmount the filesystem front-end if the mountpoint is known;
separate out back-end set-up from back-end start-up.
Add logic for converting device requests to environment variables; carry
out both post-I/O actions and pre-I/O renames when processing device
requests.
Add some example actions that make the vdev device nodes look a bit more
like those created by Debian's udev rules.
