Rework logging logic
This commit fixes issue #42 [0].
Debug level messages are masked unless option `-d' (debug) is used. In this
case, all messages are also printed to stderr.
syslog.h is included in the base POSIX only since issue 6 (POSIX:2001) [1].
`LOG_UPTO' is an extension, not defined by POSIX; an implementation is provided
here for platforms where it is missing.
This code is inspired by OpenBSD's httpd(8) logging functions [2].
