- Changed gethostname test to check in different libs.
- Customized syslog test to detect syslog even if it is a macro.

- In distributions/Makefile changed apccontrol installation so that
  if <dist>/apccontrol.sh exists it install the customized script
  instead of the standard one.
- Added HAVE_OPENSERVER_OS in autoconf/acconfig.h so that it can be
  used inside C sources too.
