compositor: Remove meta_plugin_begin/end_modal

Browse Source 
Amazingly, this is no longer used. This way to let Clutter grab input
is no longer necessary.

/**
* meta_plugin_begin_modal:
* @plugin: a #MetaPlugin
* @options: flags that modify the behavior of the modal grab
* @timestamp: the timestamp used for establishing grabs
*
* This function is used to grab the keyboard and mouse for the exclusive
* use of the plugin. Correct operation requires that both the keyboard
* and mouse are grabbed, or thing will break. (In particular, other
* passive X grabs in Meta can trigger but not be handled by the normal
* keybinding handling code.) However, the plugin can establish the keyboard
* and/or mouse grabs ahead of time and pass in the
* %META_MODAL_POINTER_ALREADY_GRABBED and/or %META_MODAL_KEYBOARD_ALREADY_GRABBED
* options. This facility is provided for two reasons: first to allow using
* this function to establish modality after a passive grab, and second to
* allow using obscure features of XGrabPointer() and XGrabKeyboard() without
* having to add them to this API.
*
* Return value: whether we successfully grabbed the keyboard and
* mouse and made the plugin modal.
