Add the ':char' syntax for defining character keys with a different
symbol.
This new kind of keys is used to implement Ctrl combinations in the
Serbian Cyrillic layout without showing latin letters while the Ctrl
modifier is activated.
This allows to add new kinds of keys that need more data without making
KeyValue's footprint bigger for common keys.
This changes the [_symbol] field into [_payload], which holds the same
as the previous field for more common keys but can hold bigger objects
for keys of the new "Complex" kind.
This also adds a complex key: String keys with a symbol different than
the outputted string.
Unit tests are added as the Java language is not helpful in making
robust code.
The 'ctrl' modmap is different from the other modmaps as it also applies
the built-in Ctrl modifier to the resulting character, even if it was
first modified by the custom modmap.
For example, this will map Ctrl+в to Ctrl+V (not to v):
<ctrl a="в" b="v"/>
This is intended to add keyboard shortcuts in non-latin layouts.
A caveat is that the latin character appears on the keyboard while Ctrl
is activated.
This allows adding more compose sequences without modifying
en_US_UTF_8_Compose.pre.
This is done by grouping sequences files that should be merged together
into a directory. This also allows moving keysymdef.h into that
directory.
* Fix persian's half-space invisibility
* Add a 0.5 space before ظ in persian
* Change the place of چ in persian

* Rename zwnj to halfspace in KeyValue.java and beng_provat layout
The arabic layout was used as the default on devices where all the
installed languages are not supported by the keyboard. This is not
intended.
This is probably caused by 'getCurrentInputMethodSubtype' returning the
first layout in the list of disabled subtypes in alphabetical or
language tag order.
Re-ordering the subtypes in method.xml had no effect.
Setting 'overridesImplicitlyEnabledSubtype' in method.xml has no
measured effect.
This adds the clipboard pane, which allows to save an arbitrary number of
clipboards and to paste them later. The key can be disabled in settings.
Checking the "Recently copied text" checkbox will cause the keyboard to keep a
temporary history of copied text. This history can only contain 3 elements
which expire after 5 minutes.
If this is unchecked, no history is collected.
History entries can be pinned into the persisted list of pins.
Internally "key repeat" is reword into "long press" when the same
mechanism was used for both features.
The constraint that 'timeoutWhat' must be set to '-1' when no message is
expected has been lifted to simplify the code.
This adds some errors:
- 'script' or 'numpad_script' is set an empty string.
- Multiple '<modmap>' elements.
- 'shift', 'width' and 'height' on every nodes that support them are
clamped to a valid value.
This replaces the switch cases in KeyModifier.java with JSON files, one
for each diacritic.
The number of states increases from 6727 to 7377. The apk size slightly
decreases (around 3kb).
