The warnings fixed by including an header file for the appropriate
prototype are marked with "*", for all others the corresonponding
symbol has been made static.  This patch fixes all such issues in
mISDN.

Impact: change data type for variable 'debug' from *int to *u_int,
same for the argument type of mISDN_inittimer

In "core.h" mISDN_inittimer is declared with the argument type "*u_int", make
the definition in "timerdev.c" match this.

This fixes also this warnings:

The driver just sets ->llseek to NULL.  It should also clear FMODE_LSEEK to
tell the VFS that seeks are not supported.

- Remove noop VFS stubs. The VFS does that on a NULL pointer anyways.
- Fix timer handler prototype to be correct
- Comment ugly SMP race I didn't fix.
