cg_get_machine_path is modified to include the escaped machine name
+ ".nspawn" if the machine argument is nonnull.

With the "--fuzz=<ms>" parameter one can display more units around
the critical units.

Make "systemd-analyze dot" output only lines with units matching
given glob(7) patterns. Add --from-pattern and --to-pattern options.
Without any patterns all relationships are printed as before.
A relationship must match the follwing expression:
(isempty(from) || from[0] || from[1] || .. || from[n]) &&
(isempty(to) || to[0] || to[1] || .. || to[n]) &&
(isempty(P) || P[0] || P[1] || ... || P[n])
where from[] and to[] are lists of patterns provided with subsequent
--from-pattern and --to-pattern respectively. P[] is a list of additional
patterns provided after the "dot" subcommand.

Instead of outputting "5h 55s 50ms 3us" we'll now output "5h
55.050003s". Also, while outputting the accuracy is configurable.
Basically we now try use "dot notation" for all time values > 1min. For
>= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and
finally 'us'.
This should give reasonably values in most cases.

Update systemd-analyze to follow the coding style of the other tools
more closely. Also, update the CODING_STYLE to document this for future
additions.
Changes:
- Always use usec_t for time units, so that we always use the same types
everywhere, and format times the same way as everywhere else.
- Add "static" to global variables
- Make sure we can always distuingish OOM and other errors: ensure we
always return useful error codes from all functions.
- Always free unit_times array

Also split out some fileio functions to fileio.c and provide a SELinux
aware pendant in fileio-label.c
