[PATCH] protocol: Add wl_text_input interface

From: Jan Arne Petersen <jpetersen at openismus.com>

wl_text_input objects are used for text input. They add support for text
input and input methods to applications. A text-input object is created
from a wl_text_input_manager and corresponds typically to a text entry
in an application.

+    <description summary="text input">
+      An object used for text input. Adds support for text input and input 
+      methods to applications. A text-input object is created from a
+      text_input_manager and corresponds typically to a text entry in an
+      application.
+      Requests are used to activate/deactivate the text-input object and set
+      state information like surrounding and selected text or the content type.
+      The information about entered text is sent to the text-input object via
+      the pre-edit and commit events. Using this interface removes the need
+      for applications to directly process hardware key events and compose text
+      out of them.
