sysklogd v2.4.1

Changes

• Fake microsecond timestamp to allow for improved log sorting:
  • in RFC3164 messages (that don't have this resolution)
  • in untrusted kernel messages
• Dropped debian/ directory (moved to separate branch), to ease
  re-packaging by downstream
• libsyslog now supports logging to remote servers, bypassing syslogd
• Major updates to logger:
  • Support for logging to a remote host, -h HOST and -P PORT
  • Support for logging in RFC3164 format, -b, mostly for remote
    logging to syslog servers that do not support RFC5424
  • Support for overriding hostname -H NAME
  • Support for custom PID, e.g., a shell scripts PID, -I PID

Fixes

• Fix #52: Prevent over-read when scanning a new-style kernel message.
  Found and fixed by Edward K. McGuire
• Fix #53: prevent log file corruption when kernel messages contain
  control codes, notably \n. Instead, preserve kernel protective
  C-style hex encoding. For example, \n embedded in a message by a
  kernel-level facility is received as \x0a. Found and fixed by
  Edward K. McGuire
• Fix #56: logging to remote machine stops after receiving a few
  SIGHUPs. Open remote socket count was not reset properly on SIGHUP.
  Problem introduced in v2.4.0. Reported by Edward K. McGuire
• Fix gettimeofday() error handling to use same fallback to time()
• Fix libsyslog opening and connecting to syslogd when LOG_NLOG is set
• Fix libsyslog so it honors LOG_PTRIM when logging to stderr
• Fix issue in RFC3164 output where the tag field could overflow.
  Spec. mandates tag never exceeds 32 characters
