define YY_NO_INPUT where appropriate, from Kurt J. Lidl per PR misc/41160

Add the `action' mode, which can be used to associate commands with mouse
button events. This mode needs to be explicitly enabled at runtime, and
does nothing if not configured.

As there are now two different modes available, adjust the manpages
accordingly, describing what they do and how they work separatedly.

While here, remove a bunch of unused stuff (event syntax) from config file
parsing. This was initially added with this new mode in mind, but it has
not been used to make it a lot simpler.

- Let the main program handle multiple run modes easily. Each one is
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.

Use both -I. for generated .h files, and -I${.CURDIR} for include "foo"

Create a pidfile while running (which can be tuned with the new "pidfile"
configuration variable). Ok'ed by christos.

Add support to parse a configuration file, /etc/wsmoused.conf by default.
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.
