[Christian Hilberg <chilberg src gnome org>]

commit bad15abe05298181ed6f0b53e1502ebce40077b0
Author: Christian Hilberg <hilberg kernelconcepts de>

    CamelIMAPXFolder: expose symbols for subclasses
    
    * added a "friend" API with its own header file,
      exposing internal CamelIMAPXFolder functions
      needed by CamelIMAPXExtdFolder
    * added a header file with temporary declarations
      of CamelIMAPXFolder-internal macros and strucutres
      for use inside CamelIMAPXExtdFolder
    * both of these can be dropped once upstream picks up
      the extended versions of our IMAPX classes
