faa8318b3b Remove the _rc_can_find_pids function
This test to find if we could see pid 1 was being used inconsistently in
rc-status and mark_service_crashed to decide whether we could test to
see if the daemon for the service was crashed, and it was not part of
the librc library.

I am removing it from the executables because of inconsistent usage. I
will add it to the library if it is needed there.

0200002b8c start-stop-daemon: don't fail stopping if pidfile is gone
If pidfile does not exist when we are stopping the daemon, assume it is
already stopped, and report success.

hostapd is an example of a daemon which removes its pidfile when it is
exiting. If this daemon terminates prematurely, that is, without s-s-d
involvement, then openrc fails to restart it, because s-s-d "stop"
command fails when pidfile is missing.

4616f8f809 helpers.h: add xasprintf function
This is our own version of asprintf(). This original code was written by
Mike Frysinger, and I was able to modify it to use our memory helper
functions.

We need a version of this code because it is not available on glibc at
least without defining _GNU_SOURCE, and I would rather not do that.

This is the first step in improving string handling in OpenRC for #207.

a7c99506d9 Fix repeated dependency cache rebuild if clock skewed
rc_deptree_update_needed would return early as soon as it found
any file newer than the existing dependency cache.  Unfortunately,
the first file found may not be the newest one there; so the
clock skew workaround in rc-misc:_rc_deptree_load would be given
a timestamp that was still too old.

This fix forces a full scan of all relevant files, so as to
ensure that we return a timestamp that will allow the clock skew
fix to operate.   The runtime cost is no worse than the case where
the cache is up to date (ie. we must check every possible file).

This fixes #161.
