An operator wanting to monitor processes started by Finit could use the
kernel ftrace framework. E.g. execsnoop in perf-tools.

This gives the operator a way to add a post-mount script, e.g. to peform
a 2nd stage mount or mount preparations, before the bootmisc.so plugin
and others run in hook/mount/all

The file plugin.h is installed to $prefix/include and used by external
plugins. Therefore it must not include, or depend on, features set by
the configure script in config.h

The SVC_RECONF, SVC_LOST, SVC_START, and RUNLEVEL_CHANGE hooks are not
one-shot, they are also not regular conditions since there exist no
mechanism to reset them from flux.
One idea was to turn them into actions, but the lost + start hooks need
to be called multiple times per trigger, e.g. `initctl reload`, which
turned out to be non-trivial to implement right now.
Therefore, for (at least) the Finit v3.1 release these conditions have
been disabled ("nop") and ignored by Finit. Only actual C-style plugins
will be called.

The /lib/finit/plugins path is as of this patch not longer possible to
change. Use --prefix or --libdir instead to change the leading path.

This patch implements support for calling run/task jobs on the built-in
`HOOK_*` points in Finit. To map each HOOK point to a condition a new
classification was made, as shown in plugin.h and in the example below.
task <hook/mount/root> /sbin/attachubi.sh # run in parallel with other tasks/services
run <hook/net/up> /sbin/dosomething.sh # run in sequence with other commands
Please note, only rudimentary tested.
