i.e., don't check for the end of the list by ->name == NULL, since that
won't work now. Fix the consumers of xf86DefaultModes to use the new
explicit size as well.
Old heuristic was to find the first monitor that expressed a preference,
then attempt to get all other monitors to agree. This doesn't work
particularly well when the two sets of modes don't precisely intersect,
you get overlapping-but-not-identical output geometry and things go wrong.
New heuristic is:
- Exact user preference, if given
- Exact output preference, if the same for all outputs
- Best (largest) mode of modes common to all outputs:
- with the same aspect ratio as all outputs (may be NULL)
- with 4:3 aspect ratio
- Then the old heuristic to try to get something lit
Note that it is simply not doable to have a reliable initial output guess if
you insist on trying to clone all outputs together. It's far too easy to
end up with displays that simply don't have modes in common. We need to
switch to right-of placement someday, once we're not limited to CRTC size
limits and we have working multi-GPU in RANDR.

Due to an unwitting sense inversion when eliminating XkbFileInfo, we were
setting the complete wrong keymap on startup (non-XKB map if we had an XKB
map available, or the XKB map if we didn't have any available). Invert the
sense properly, and add two small bits that also went missing in that commit.

If you don't do this, then Modes "800x600" in the Display subsection will
be dutifully ignored and the driver will start at whatever resolution it
feels like.
CVT is enough different from GTF that it should not be used on monitors
that aren't expecting it. This brings us closer to what the spec says
the correct behaviour is.
Before this it was meaningless to try to mark DisplayModeRec tables
const, since the mode name would be emitted as a pointer to an
anonymous string constant, and therefore would have to be fixed up by
ld.so and so couldn't live in .rodata. With this change the standard
mode lists can live in .rodata, and modes duplicated from them will
have their names filled in on the fly.
