syslogd: Use closefrom() instead of getdtablesize()/close()
loop.

When syslogd forks a process for '|' destinations, it closes all file
descriptors greater than 2.

Use closefrom() for this instead of a getdtablesize()/close() loop because
it is both faster and avoids leaving file descriptors open because the limit
was lowered after they were opened.

add support for ipv6 addresses as destination.
