wrappers for err, errx, warn and warnx respectively when running in foreground
and call syslog functions when running in daemon mode.
Also add and use an extra log_info function for other types of information.
described by a structure with pointers to functions.
- Clearly separate the "selection" mode (which provides copy and paste support
in console) from wsmoused's main program.
- Added the "modes" property to the configuration file and the "-m" command
line option to specify which modes should be activated. (this is mostly
useless for now, as only the "selection" mode exists; a new mode will
be added soon, hopefully).
- While here, several style fixes according to share/misc/style.
This file lets users tune the behavior of the daemon in a easy way, without
having to mess with command line options (nor in rc.conf).
It will also simplify future integration of new functionality within the
program as multiple "modes" of operator are recognized.
The new wsmoused.conf(5) manpage contains all related details.
Some error message cleanup and minor manpage fixes too.
Ok'ed by christos.
