It's a name of a function in scanner-utils.h and also of some
parameters.

If count % SIZE == 0 we did a useless iteration where start==stop. It's
harmless but strange, so don't do that.

matcher_match() builds up the kccgst's, and we steal the memory on
success. But on error we didn't free it.

Two problems:
- `j` can be >= `SIZE`, and needs to be wrapped like in the rest of the
code.
- `cookies[j % SIZE]` is not initialized if there's no atom in `from[j]`.
The is manifested when:
- We've already gone through one batch (>= 128 atoms) (in fact this
cannot happen in call to `adopt_atoms` in the current code).
- An XCB request failed in the middle of a batch.

Instead just statically allocate the mods array (of size MAX_MOD_SIZE =
32). The limit is not going anywhere, and static allocations are nicer
(nicer code, no OOM, etc.). It's also small and dense enough.

The keymap is not removed entirely from the Info (just constified),
since it is still needed in AddKeySymbols() for looking up aliases. This
dependency will be removed in the future.

This is the only place where the modifier information is modified. We
will make it local to a given XKB file (after which it will be merged
into the keymap). Currently it changes the keymap directly, which
sidesteps the abstraction and leaves side-effects even if the XkbFile's
compilation fails.

The modifier printing functions only need the modifier information, they
don't care about keys or leds, etc.

The only thing that the compilation phase needs the keymap for currently
is for access to the modifier information (it also modifies it in
place!). We want to only pass along the neccessary information, to make
it more tractable and testable, so instead of passing the entire keymap
we add a new 'mod_set' object and pass a (const) reference to that.
The new object is just the old array of 'struct xkb_mod'.

Separate the ctx object to its own field in CompatInfo, instead of doing
keymap->ctx.
The compilation functions should not have direct access to the keymap;
instead they should process the files with their own independent state
(in the *Info structs) as much as possible, and only at the end should
they be copied (i.e. commited) to the keymap. If the compilation fails,
it leaves no by-products. It's also just good form.
This was seemingly the original author's intention, but I suppose he cut
a few corners (mostly with the handling of virtual modifiers, which are
threaded through types -> compat -> symbols).
This commit is the first step and may look artificial; however the
'keymap' field will be removed shortly.

The current calculation is in short:
entry ? (entry->mask & ~entry->preserve) : 0
This changes it be
type->mask & ~(entry ? entry->preserve : 0)
This is what Xlib does. While less intuitive, it is actually more
correct, if you follow this deduction:
- The key group's type->mask defines which modifiers the key even cares
about. The others are completely irrelevant (and in fact they are
masked out from all sided in the level calculation). Example: NumLock
for an alphabetic key.
- The type->mask, the mods which are not masked out, are *all* relevant
(and in fact in the level calculation they must match *exactly* to the
state). These mods affect which level is chosen for the key, whether
they are active or not.
- Because the type->mask mods are all relevant, they must be considered
as consumed by the calculation *even if they are not active*.
Therefore we use type->mask instead of entry->mask.
The second change is what happens when no entry is found: return 0 or
just take preserve to be 0? Let's consider an example, the basic type
type "ALPHABETIC" {
modifiers = Shift+Lock;
map[Shift] = Level2;
map[Lock] = Level2;
level_name[Level1] = "Base";
level_name[Level2] = "Caps";
};
Suppose Shift+Lock is active - it doesn't match any entry, thus it gets
to level 0. The first interpretation would take them both to be
unconsumed, the second (new one) would take them both to be consumed.
This seems much better: Caps is active, and Shift disables it, they both
do something.
This change also fixes a pretty lousy bug (since 0.3.2), where Shift
appears to apparently *not* disable Caps. What actually happens is that
Caps is not consumed (see above) but active, thus the implicit
capitalization in get_one_sym() kicks in and capitalizes it anyway.

These functions generally have the same effect as
xkb_state_key_get_syms() + xkb_keysym_to_utf{8,32}().
So why add them?
- They provide a slightly nicer interface, especially if the string is
the only interest.
- It makes the handling of multiple-keysyms-to-utf8 transparent. For the
designated use-case of multiple-keysyms (unicode combining
characters), this is a must. We also validate the UTF-8, which the
user might not otherwise do.
- We will need to apply some transformation on the resulting string
which depend on the xkb_state. This is not possible with the
xkb_keysym_* functions.
With these functions, the existing xkb_keysym_to_utf{8,32}() are not
expected to be used by a typical user; they are "raw" functions.

We need to validate some UTF-8, so this adds an is_valid_utf8()
function, which is probably pretty slow but should work correctly.

It is valid for a keymap to not have key aliases, group names and
various other things. But the current test requires all of them to be
present in the reply, which causes us the fail on such keymaps (as the
XQuartz one).
Instead, require only what we really need. The virtual-mods names may
not be strictly required, but it seems safer to leave it in for now.

Nothing bad can come out of it, but for some reason this error didn't
return early (inherited from xkbcomp).
Also promote the log message to an error, as it clearly is.

This retrieves the mask of consumed modifiers for a given key and state,
which is helpful for toolkits without having them to do it one modifier
at a time, or pass in 0xFFFFFFFF to xkb_state_remove_consumed_mods to
"reverse-engineer" the consumed mods.
This is a little shorter and follows easier from the spec flag
description table.
Also a few were too permissive (like allowing LatchToLock in SetMods).

This used to *unset* a flag called "SwitchApplication"; we changed the
flag to "same" but forgot to switch the cases.
