This is a small series that cleans up struct consw a bit and
prepares it for Control Flow Integrity checking (i.e. Clang's
-fsanitize=cfi).
Thanks!

As done in commit:
724ba8b30b04 ("console/dummy: leave .con_font_get set to NULL")
This drops the dummy .con_font_get(), as it could leave arguments
uninitialized.

Reading the function declarations for the console callbacks lacks any
hints as to what the arguments are. Instead of going and digging around in
various implementations that may each only have a subset of the callbacks,
name all the arguments in the declaration. This has no functional change.

This expands the no-op dummy functions into full prototypes to avoid
indirect call mismatches when running under Control Flow Integrity
checking, like with Clang's -fsanitize=cfi.

I've already taken this through the tty tree, sorry about that.
Shouldn't cause any merge issues.
