Sometimes people type in the wrong path to a service directive in finit.conf, or the executable isn't installed. This commit makes sure to check if the command exists before attempting to start it. This also means that we now require service commands to start with / to indicate an absolute path. We used to search the PATH for a suitable executable, using execvp(), but that's rather insecure as well, so we now use only execv(). Also, added support for adding "start" or "stop" to entries found in /etc/finit.d starting with SNNname, or KNNname, where NN is a number. This makes it possible to simply import sysvinit style start scripts from /etc/rcS.d and /etc/rcN.d/. The alsa-utils plugin also had some minor fixes, added -g option to ignore non-existing soundcards and fixed cut-paste bug on the _d() debug messages.
