Upgrade mdev to allow commands to be run on create/delete.
Both Jason Schoon and Giuseppe Ciotta deserve credit for this, I used elements
of both. It's been upgraded so that you can specify that a given command
should run at create, at delete, or at both using different special characters
(@, $, and * respectively). It uses the system() method of running command
lines which means you can use environment variables on the command line (it
sets $MDEV to the name of the current device being created/deleted, which is
useful if you matched it via regex), and the documentation warns that you need
a /bin/sh to make that work, so you probably want to pick a default shell.
