Fix issue #18942959: Phone getting stuck then restarts after unplugging from Audi

FastPrintWriter needs to have its own lock for each instance, or
else one getting blocked can cause others to block and whacky deadlocks
result.

Also:

- Improve error reporting of SystemConfig to tell you which config
  file is the problem.
- Fix CoreSettingsProvider to not spew errors if a setting is not
  defined (it should just use a default value).
- Get rid of noisy init output of ConditionProviders.
- Reduce log noise of starting a process; move some of that information
  to ProcessRecord to print on demand.
