New input handling framework

[jteh]

NVDA needs a new, flexible input handling framework.

• It must handle input from sources other than the keyboard; e.g. Braille displays.
  • Multiple variants of a single source should be handled also; e.g. desktop and laptop keyboard layouts.
• It should allow input from all sources to execute scripts, as well as facilitating keyboard/input help.
• There should be an input gesture class hierarchy. All input gestures will create an input gesture instance.
• Scripts should receive an input gesture instance instead of a key press.
• It should allow scripts common to multiple targets (e.g. say all) to be specified in a single mapping.
• Users should be able to override all entries without having to edit builtin maps.
• It should be possible to re-send the gesture for sources which support it. This would be used instead of sendKeyPress.
• Bindings for all input sources should be specified in the same map file.

Bzr branch:  http://bzr.nvaccess.org/nvda/inputFramework/
As of rev 3411, keyboardHandler has been changed to use input gestures. However, work hasn't yet begun on the new mapping system.

(In #620) Already fixed as part of the work on the new input framework (#601).

(In #639) This is easy to do. We should also implement shift+ctrl+up/down, since there are ctrl+up/down.

Let's do this after inputFramework, as it will cause merge conflicts otherwise.

Probably want to get this into 2010.2, not least because merging it later will be painful.

(In #558) Done as part of input framework.

[jteh]

As of inputFramework rev 3449, functionality should be equivalent to that in main. Work has not yet begun on the new map file format nor braille input gestures.

Merged inputFramework in changeset:main,3885.

The new mapping system hasn't yet been implemented. This means that the following features still aren't present:
Replying to jteh:

• It should allow scripts common to multiple targets (e.g. say all) to be specified in a single mapping.
• Users should be able to override all entries without having to edit builtin maps.
• Bindings for all input sources should be specified in the same map file.

However, the core framework (gestures, etc.) is done. Therefore, I'm closing this ticket as fixed. I'll open new tickets/hijack other tickets for features based on this framework.
