Input prefs: handle errors

Various error handling cases were missing, which would lead to corrupt
settings and crashes. Add the missing error checks and make sure we
always revert to sane settings in case of problems.

Input: fix infinite loop

Right shift on a signed value can extend the sign bit, which would make
this function do an infinite loop if passed a negative value. Use an
unsigned instead to get the behavior we want.

Fixes #15957, but this means we're using undefined data from the
settings file. I assumed it would have the unused button values set to 0
but this isn't apparently the case. Preetpal is already working on that
as we noticed the problem when testing her patch for adding a 6th
button.

Actually handle more than 3 mouse buttons

The code in input_server was pretty much all set for this, but there was
no way to configure the extra buttons. Add them to the mouse view in
Input preferences (up to 5 buttons are handled now)

Define a new B_MOUSE_BUTTON(n) macro to generate the bitmask for a given
button (numbered from 1).
