Here we catch up, after the default config changes.
o the man page is updated to reflect the new default config
o /etc/udev/rules.d/ + permissions.d/ dirs are created now
o udev.rules is installed in /etc/udev/rules.d/50-udev.rules
so the user can easily order the files by prepending a number.
(RedHat has the same name in the last rpm.)
o defined directory names in the Makefile are all without slashes now,
not the first half with and the remaining without.
o all binaries are uninstalled now
o leading slashes in config values are now removed or prepended while the
config is parsed, so we are more robust if the usere changes something.
o replaced the macros from udev_config.c with real code, cause we can
skip if the value matches and not useless iterate over the remaining
fields.
o config parsing errors are logged with info() now, fixes the bug where
we report a error with debug_parse(), even when there isn't one
