- exec_t belongs to service.h, the main place where it is used/needed
- code for executing exec_t is moved to runsvc for the same reason
- what is left are NORETURN and ARRAY_SIZE
- the former can be replaced with direct attribute usage since
the only relevant compilers all support the attribute.
- the later is only used in 3 places and can be trivially replaced
with direct usage of sizeof().

Targetting anything else than Linux isn't really relevant. All
other systems ($BSD and other Unices) are a closed ecosystem
where kernel & userspace are developed together. They don't need
something like a third party init system, so compatibillity can
be largely ignored.

We also want this meachanism to still work for manually started
service (especially after reloading services).

This commit add the ability to initd to reload the service configuration
while running. The new configuration is merged with the existing one as
follows:
For each target:
- If the existing service list is not NULL, we have not started that
target yet. Simply replace it with the new list.
- If it is NULL, the services have already been started.
- First, remove all entries for services in that target that no
loner exist (except from the 'running' list).
- Second, add new services that we don't have yet. Treat them as
recently diseased and let the user start them manualy.

First in rdsvc, tag the services that *do* have exec lines, even if we don't
read them.
Second, if a service does not have that flag set, don't try to execute it.

- mimic format of initd
- skip formatting if not a tty
- distinguish exited because failed vs exited because done

We no longer need to keep entire scripts in init program (i.e. saving space)
and reduce the code and complexity of the init program.
The runsvc tool can later be extended to do more complex child setup, such
as configuring namespaces or seccomp without adding complexity or memory
footprint to init.

- Common function for splitting string into argument vector
- Preprocess & split command lines while parsing the service file
