Can happen in cases like:
- There was an error between the error check and the call.
- The internal poll() fails.

The current functions dealing with consumed modifiers use the
traditional XKB definition of consumed modifiers (see description in the
added documentation). However, for several users of the library (e.g.
GTK) this definition is unsuitable or too eager. This is exacerbated by
some less-than-ideal xkeyboard-config type definitions (CTRL+ALT seems
to cause most grief...).
So, because we
- want to enable alternative interpretations, but
- don't want to expose too much internal details, and
- want to keep things simple for all library users,
we add a high-level "mode" parameter which selects the desired
interpretation. New ones can be added as long as they make some sense.
All of the old consumed-modifiers functions keep using the traditional
("XKB") mode. I mark xkb_state_mod_mask_remove_consumed() and as
deprecated without adding a *2 variant because I don't it is very useful
(or used) in practice.
Alternative modes are added in subsequent commits (this commit only adds
a mode for the existing behavior).

Takes care of GCC's annoyingly persistent warn_unused_result warnings.
But it's better to avoid system() I suppose.

- Specify in detail which parts of the events we care about. In theory
the X server should not bother us with things we didn't ask for. In
practice it still does, but oh well.
- Use the _aux version of select_events. This is the correct one to use,
the non-aux version is useless.

Add two tests:
./test/interactive-x11
which is like test/interactive-evdev, but should behave exactly like your
X keyboard and react to state and keymap changes - in other words, just
like typing in xterm. Press ESC to exit.
./test/x11
which currently should only print out the same keymap as
xkbcomp $DISPLAY out.xkb
(modulo some whitespace and some constructs we do not support.)
