GtkEntryBuffer holds text for GtkEntry

Browse Source 
Adds a 'model' type buffer for GtkEntry in which the actual
textual data is stored. GtkEntryBuffer can be subclassed.

Among other things, this allows GtkEntry to be used for secrets
that need to be stored in non-pageable memory. It also allows
buffers to be shared by entries.

See bug #576801.
