These were repeated 5 times.
Note that this changes the ABI slightly: XKB_MOD_NAME_CAPS is changed
from "Caps Lock" to "Lock", which is the ordinary legacy mod name for
it. Since its hidden behind a #define, it's best to stay compatible with
the old names (as I think was intended, given that "Mod1", etc. are the
same).

The program reads key events from evdev input devices, puts them through
the library and prints some information about them. It's nice for
experimenting, quick testing and trying to break it with random stuff
(already found some!).
It is called "interactive" for lack of a better name. It's a bit
hackish, but can easily be extended, made more portable etc, in the
future.

Convert the IdentLookup typedef away from ExprResult, which drags along
everything else. This should also make all of the conversions explicit.

As the comment nicely puts it, this is a bit weird. When you try to
evaluate an expression of type string into an integer, what it does is:
"" -> 0
"c" -> (ascii value, i.e. like a char literal)
more than one char -> error
The first one is obviously not very useful; why not just write 0?
The second one might be useful (though I don't see where in a keymap
it would be), but I don't think anyone would consider trying "X" for
that anyway.
A look through xkeyboard-config shows "" only used once as a string, and
"X" also only used as strings (and mostly in geometry which we don't
evaluate anyway). And I seriously doubt it's used (purposely) anywhere
else. So remove it.

Clean up the return code handling from
xkb_context_add_include_paths_default, and thus fail context creation if
we can't add any of the default include paths, but were asked to. If
this happens, dump the DFLT_XKB_CONFIG_ROOT out in the log message, so
at least we know what we aren't looking at.

Explicit is better than implicit, and this union makes it hard to follow
what's what, particularly the confusion with ival/uval.
The other Resolve functions will follow.

It's more tidy and less error prone, since we use strcasecmp == 0 a lot.
We replace strcmp == 0 by streq, strcasecmp == 0 by istreq,
uStrCasePrefix by istreq_prefix and uDupString by strdup_safe.

The key name is always XkbKeyNameLength (= 4) bytes, so we can maintain
it directly in YYSTYPE union and copy when needed, instead of treating
it like a full blown string and then copy. This means the scanner
checks the length itself.

We often get a strdup'd string, just to pass it over the atom_intern and
then immediately free it. But atom_intern then strdup's it again (if
it's not interned already); so instead we can have the interning "steal"
the memory instead of allocing a new one and freeing the old one. This
is done by a new xkb_atom_steal function.
It also turns out, that every time we strdup an atom, we don't actually
modify it afterwards. Since we are guaranteed that the atom table will
live as long as the context, we can just use xkb_atom_text instead. This
removes a some more dynamic allocations.
For this change we had to remove the ability to append two strings, e.g.
"foo" + "bar" -> "foobar"
which is only possible with string literals. This is unused and quite
useless for our purposes.
xkb_atom_strdup is left unused, as it may still be useful.

Without the re-initialization, the copying fails. This wasn't noticed
because this code practically never gets executed with ordinary keymaps.
