This is only relevant to the virtualModifier= statement in interpret
statements in xkb_compat. The current code allows to write e.g.
virtualModifier = 4
to get the virtual modifier whose index happens to be 4 (possibly
declared in other files or sections, i.e. xkb_types). Doing this is
undeterministic, will break without notice, and not used anywhere.
Don't allow it.

The current code supports statements such as:
virtual_modifiers NumLock = Mod2;
This would set the mapping from the NumLock vmod to the Mod2 real mod
directly, without going through the virtualModifier field in an
interpret statement (in xkb_compat) or vmods field in a key statement
(in xkb_symbols).
This is undocumented, unused and complicates things, so remove it.

It's currently possible to write something like this:
interpret Num_Lock+Any {
virtualModifier = NumLock;
action = LockMods(modifiers=NumLock);
!indicator.allowExplicit;
};
The final statement has the same effect as writing it in the global file
scope, which changes the default indicator (which all subsequent
indicators start off as). This very strange and also unused; if someone
does it he probably expects it to affect only the local scope, and he
might then get unexpected behavior. So don't allow it.
Also, HandleInterpVar is clearly a misnomer (as it can also change
indicator defaults) so rename it.

Using !allowExplicit sets the XkbIM_NoExplicit flag of the indicator,
which means that an XKB client cannot change the state of the indicator
using e.g. XkbSetNamedIndicator().
We do not support changing the state of an indicator; furthermore doing
it is probably only useful in conjunction with led-drives-keyboard
behavior, which we also do not support. This is because setting an
indicator without led-drives-keyboard would make the indicator and the
modifier/group it's bound to to get out of sync.
We can re-add this if we need this info.

We don't support it, as mentioned in the README, so we should stop

Group compatibility statements are like the following:
group 3 = AltGr;
This currently results in:
keymap->groups[2].mask = <real mod mapped from AltGr vmod>
And we don't do any thing with this value later. The reason it exists in
XKB is to support non-XKB clients (i.e. XKB support disabled entirely in
the server), which do not know the concept of "group", and use some
modifier to distinguish between the first and second keyboard layouts
(usually with the AltGr key). We don't care about all of that, so we can
forget about it.
One artifact of this removal is that xkb_map_num_groups no longer
works, because it counted through keymap->groups (this wasn't entirely
correct BTW). Instead we add a new num_groups member to the keymap,
which just hold the maximum among the xkb_key's num_groups. This also
means we don't have to compute anything just to get the number of
groups.

Now that 1fba6189e67 removed support for binding indicator maps by index
instead of name, we can remove some more magic which happens now: if an
indicator map specifies an indicator name which was not previously
declared in a 'indicator 5 = "Caps Lock"'-like statement in
xkb_keycodes, we can just look at the next free index and assign it.
This also allows us to use a darray for the LEDInfo's instead of a list.

The current code allows to set the "index" field in an indicator
statment's body. This would bind the indicator to the specified index,
instead of by name (which was declared previously in xkb_keycodes).
Doing this is a bad idea, for the same reasons as in 3cd9704, and is
also happily not used anywhere.

The xkblib spec, table 7.1 (indicators), says:
XkbIM_NoAutomatic: Xkb does not automatically change the value of the
indicator based upon a change in the keyboard state,
regardless of the values for the other fields of the
indicator map.
xkbcomp (the real one) never actually implemented a way for an indicator
statement to set this flag, so it's just dead unused code. We definitely
don't want to implement it ourselves, so remove any mention of it.

Since we now handle empty model/layout, the last couple of tests should
not fail. The reason they do is bacause they try to use a non-existent
"base" rules file. When the file is brought in these tests do not fail.
Since we already test for non-existent rules file, we can remove them,
and refine the other tests a bit.

Various non-functional changes:
- Re-add keycodes.h and move some stuff there.
- Add parser-priv.h for internal bison/flex stuff.
- Don't include headers from other headers, such that file dependencies
are immediate in each file.
- Rename xkbcomp.h -> ast.h, parseutils.{c,h} -> ast-build.{c,h}
- Rename path.{c,h} -> include.{c,h}
- Rename keytypes.c -> types.c
- Make the naming of XkbFile-related functions more consistent.
- Move xkb_map_{new,ref,unref} to map.c.
- Remove most extern keyword from function declarations, it's just
noise (XKB_EXPORT is what's important here).
- Append XKBCOMP_ to include guards.
- Shuffle some code around to make all of this work.
Splitting this would be a headache..

And use union xkb_action instead. We add xkb_private_action, which is
the same as xkb_any_action, but only used where the intention is clear.
This should take care of whatever sizing changes the action struct might

If this keymap flag is set, whenever a key name appears in one of the
sections which does not exist (i.e. has not been declared in keycodes),
it finds the first unused keycode and attaches it that name.
This might have been useful when you could compile the symbols section
or geometry section without a keycodes section, but we don't support
this anymore. It's also pretty useless for any real work, because the
user has no way of knowing the keycode and so it will never be used.
Finally the only obscure way left to set this flag is by including a
keycodes file called "computed".
Just remove it.

Make more extensive use of get_entry_for_key_state, and add
key_get_consumed to use in the other consume functions.
There's also a slight change in the consumed mods calculations, where
we use entry->mods.mask instead of type->mods.mask. The original was
copied from what libX11 does but what we do now is more logically
correct. The result is exactly the same though because:
type->mods.mask ⊇ entry->mods.mask ⊇ entry->preserve.mask

The group/level types are unsigned, so it's odd to return -1 for them.
Instead use their invalid values (which happen to be == -1).

Currently xkb_mods has the following members:
- uint8_t real_mods - 8 X11 core mods
- xkb_mod_mask_t vmods - 16 virtual mods, zero-based index
- xkb_mod_mask_t mask - the computed effective *real* modifier mask,
basically a cache for the first two which is:
real_mods | real mods computed from vmods
Our API acts on masks which combine the real_mods and vmods into a
single value, which is:
8 first bits real mods | 16 next bits virtual mods
(XkbNumModifiers = 8, XkbNumVirtualMods = 16). This is also the format
which ResolveVModMask uses (which is where all the modifier masks really
"come from", e.g. "Shift+Lock+Level5" -> xkb_mod_mask_t).
What the code does now after getting the mask from ResolveVModMask, is
to break it into real part and virtual part and store them seperately,
and then join them back together when the effective mask is calculated.
This is all pretty useless work. We change xkb_mods to the following:
- xkb_mod_mask_t mods - usually what ResolveVModMask returns
- xkb_mod_mask_t mask - the computed mask cache
And try to consistently use the word "mods" for the original,
non-effective mods and mask for the effective mods (which can only
contain real mods for now, because things break otherwise).
The separation is also made clearer. The effective masks are computed by
UpdateModifiersFromCompat after all the sections have been compiled;
before this the mask field is never touched; after this (i.e. map.c and
state.c) the original mods field is never touched. This single execption
to this rule is keymap-dump.c: it needs to print out only the original
modifiers, not computed ones. This is also the reason why we actually
keep two fields instead keeping one and modifying it in place.
The next logical step is probably to turn the real mods into vmods
themselves, and get rid of the distinction entirely (in a compatible
way).

After compiling all of the sections, UpdateModifiersFromCompat does all
of the vmod -> real mods translations, including types/kt_entries.
keytypes.c also has code that does that, but it's unneeded:
- Later sections don't look at their effective masks, so doing it later
is fine.
- When this code is executed, the vmods -> real mods mapping is empty
(that is set up later), so VModsToReal has no effect here.
So we can just remove it.
However UpdateModifiersFromCompat didn't update the preserve mask, so do
that.

We don't need the indirection. We store the preserve mask directly in
the entry, and create a new one if it doesn't exists (which is exactly
what the current code does in a roundabout way).
Incidentally this fixes a bug where the effective modifier mask of the
entries' preserve[] wasn't calculated, so the virtual modifiers had no
effect there.
