modules: Add wayland IM implementation
This IM context implementation goes through the gtk-text-input protocol,
leaving up to the compositor the actual interaction with IM engines.

+ <interface name="gtk_text_input" version="1">
+ <description summary="text input">
+ The gtk_text_input interface represents text input and input methods
+ associated with a seat. It provides enter/leave events to follow the
+ text input focus for a seat.
+
+ Requests are used to enable/disable the text-input object and set
+ state information like surrounding and selected text or the content type.
+ The information about the entered text is sent to the text-input object
+ via the pre-edit and commit_string events. Using this interface removes
+ the need for applications to directly process hardware key events and
+ compose text out of them.
+
+ Text is valid UTF-8 encoded, indices and lengths are in bytes. Indices
+ have to always point to the first byte of an UTF-8 encoded code point.
+ Lengths are not allowed to contain just a part of an UTF-8 encoded code
+ point.
+
+ Focus moving throughout surfaces will result in the emission of
+ gtk_text_input.enter and gtk_text_input.leave events. The focused
+ surface must perform gtk_text_input.enable and
+ gtk_text_input.disable requests as the keyboard focus moves across
+ editable and non-editable elements of the UI. Those two requests are not
+ expected to be paired with each other, the compositor must be able to
+ handle consecutive series of the same request.
+
+ State is sent by the state requests (set_surrounding_text,
+ set_content_type and set_cursor_rectangle) and a commit request.
+ After an enter event or disable request all state information is
+ invalidated and needs to be resent by the client.
+
+ This protocol defines requests and events necessary for regular clients
+ to communicate with an input method. The gtk_input_method protocol
+ defines the interfaces necessary to implement standalone input methods.
+ If a compositor implements both interfaces, it will be the arbiter of the
+ communication between both.
+
+ Warning! The protocol described in this file is experimental and
+ backward incompatible changes may be made. Backward compatible changes
+ may be added together with the corresponding interface version bump.
+ Backward incompatible changes are done by bumping the version number in
+ the protocol and interface names and resetting the interface version.
+ Once the protocol is to be declared stable, the 'z' prefix and the
+ version number in the protocol and interface names are removed and the
+ interface version number is reset.
