Subject[PATCH v1 1/6] tiocl.h: Change/Add defines for mouse report
Add additional defines for mouse event types. The change of the value
of TIOCL_SELBUTTONMASK deserves a bit more explanation :

The old value of 15 uses the first 4 bits and sends them unchanged back
to userspace if requested by an application. But in fact only the first
two bits have ever been used by any daemon or useful at all, as the
kernel already knows the status of the shift and alt keys encoded in
bits 3 and 4. On the other hand we *do* want to know the status of bits
6-8, encoding button values >3 and mouse move and drag operations.

This change is up- and downwards compatible by masking all spourious
bits and leaving only the undisputed parts (bits 1 and 2) untouched.
