[PATCH v2 0/6] Fixes for early logging/prints and related cleanups

[Stefano Brivio <sbrivio@redhat.com>]

The most apparent issue fixed by this series is the one from 3/6: with
a log file configured, we wouldn't print to standard error anymore,
during initialisation, which means that users such as libvirt lost
the ability to report meaningful error messages that occurred during
initialisation, in that case.

v2:
- turn flag bitmap into simple, separate boolean flags
- move errno description after message in _perror() functions
- make some of the old perror() messages more descriptive

Stefano Brivio (6):
  conf, passt: Don't try to log to stderr after we close it
  conf, log: Instead of abusing log levels, add log_conf_parsed flag
  log, passt: Always print to stderr before initialisation is complete
  log: Add _perror() logging function variants
  treewide: Replace perror() calls with calls to logging functions
  treewide: Replace strerror() calls
