Ran Benita babc9e0c30 state: add GTK consumed modifiers mode
This is more or less what is implemented here:
https://git.gnome.org/browse/gtk+/tree/gdk/x11/gdkkeys-x11.c?h=3.19.10#n1131

The implementation here is more technically correct but should provide
the same results.

Try it out with ./test/interactive-evdev -g (modifiers prefixed with "-"
are consumed).

There is really no reason to deny these tests from different platforms
only for a few #defines.

The only linux-only test (or test program, it is not run by make check)
is interactive-evdev, which actually uses evdev.

Ran Benita 5417440970 state: fix consumed modifier calculation
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.

Ran Benita b973d71e82 state: add xkb_state_key_get_{utf8,utf32}() API functions
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.

Ran Benita 2a2a8d7da1 state: apply capitalization transformation on keysyms
The xkbproto spec says:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Lock_Modifier

    If the Lock modifier is not consumed by the symbol lookup process,
    routines that determine the symbol and string that correspond to
    an event should capitalize the result.

This was not an issue until now, because most xkeyboard-config keymaps
do not utilize this "feature", and specify the keysyms for the Lock
modifier explicitly instead. However, some keymaps do depend on it, e.g.
ch(fr) for eacute and others.

The spec goes on to describe two options for doing this transformation:
locale-sensitive and locale-insensitive. We opt for the latter; it is
less desirable but we don't want *that* headache.

Also, only xkb_state_key_get_one_sym() is changed;
xkb_state_key_get_syms() is left as-is, and always reports the
untransformed keysyms. This is for the following reasons:

- The API doesn't allow it, since we return a const pointer directly to
  the keymap keysyms table and we can't transform that.

- The transformation doesn't make sense for multiple-keysyms.

- It can be useful for an application to get the "raw" keysyms if it
  wants to (e.g. maybe it wants to do the transformation itself).

Finally, note that xkb_state_mod_index_is_consumed() does *not*
report Lock as consumed even if it was used in the transformation. This
is what Xlib does.

This definitely doesn't fall under the "hard to misuse" API rule but
it's the best we can do.

Ran Benita 6a94b122a4 Split the mods, layout, leds parts of xkb_state_components
Note first:
This commits breaks the ABI somewhat. If an application is run against
this commit without recompiling against the updated header, these break:
    - xkb_state_layout_*_is_active always retuns false.
    - xkb_state_serialize_mods always returns 0.
So it might break layout switching in some applications. However,
xkbcommon-compat.h provides the necessary fixes, so recompiling should
work (though updating the application is even better).

Split the enum to its individual components, which enables us to refer
to them individually. We will use that later for reporting which
components of the state have changed after update.

Ran Benita bbf388ec1f Make xkb_keymap_num_leds return the index range instead of active count
Currently xkb_keymap_num_leds() returns a count of valid (settable)
leds. Because the indexes might be non-consecutive, and some leds
might not be settable, it is incorrect to use this function for
iterating over the leds in the keymap. But this is the main use case of
this function, so instead of the current behavior we adapt the function
to the use case by making it return the needed range of iteration.
The caller needs to handle invalid intermittent indexes, though.

Ran Benita 2f4db8a95b keymap, state: don't assume led index < xkb_keymap_num_leds
xkb_keymap_num_leds() returns the number of leds that have any
possibility of being set. Even if a led is defined but can not be set in
any way, it is not counted.

In a few places currently we assume that led indexes are smaller than
this number, which is wrong both for the above reason and for the fact
that the xkb format actually allows explicitly setting the indicator
index, which means that the indexes might be non-consecutive.

We don't really have good API to iterate on leds, now, because
xkb_keymap_num_leds is pretty useless. To work around that we use
sizeof(xkb_led_mask_t) * 8.

This makes the "Group 2" led work (try switching to a layout other than
the first in test/interactive).

Ran Benita 1a6b1e0788 state: fix bad EFFECTIVE check in *_is_active()
This is a regression introduced in ed78fbcb30.
XKB_STATE_EFFECTIVE is just a OR of the other states, so using & here is
completely wrong. So test/state shows for example:
    dumping state for LCtrl down:
            group English (US) (0): effective depressed latched locked
            mod Control (2): depressed latched locked
    dumping state for LCtrl + RAlt down:
            group English (US) (0): effective depressed latched locked
            mod Control (2): depressed latched locked
            mod Mod1 (3): depressed latched locked
    dumping state for RAlt down:
            group English (US) (0): effective depressed latched locked
            mod Mod1 (3): depressed latched locked
    dumping state for Caps Lock:
            group English (US) (0): effective depressed latched locked
            mod Lock (1): depressed latched locked
            led Caps Lock (0): active
    dumping state for Alt-Shift-+
            group English (US) (0): effective depressed latched locked
            mod Shift (0): depressed latched locked
            mod Mod1 (3): depressed latched locked
which is bogus.

Ran Benita 4b49e0a117 Overhaul test suite
Rewrite all of the current tests in the following ways:
- Instead of the current mix of C and shell, just use single-process
  pure C file per test. All of the .sh files are removed, but everything
  that was tested is ported.
- Instead of handling the test logs ourselves, use Automake's
  "parallel-test" mechanism. This will create a single log file for each
  test with it's stdout+stderr, and a top level "test-suite.log" file
  for all the failed tests.
- The "parallel-tests" directive also makes the test run in parallel,
  so "make check" runs faster.
- Also use the "color-tests" directive to have the "make check" output
  colorized. Who doesn't like to see PASS in green?
- All of the test data files are moved into the test/data subdirectory.
  That way we can just put the directory in EXTRA_DIST and forget about
  it.
- The test/Makefile.am file is consolidated into the main Makefile.am,
  for a completely non-recursive build.

Right now the tests are completely independent and just use simple
assert()'s. More sophistication can be added as needed.

It should also be noted that it's still possible to use shell, python,
etc. if a test wants more flexibility than C can provide, just do as
before.
