Re: [patch 9/9] pdfedit-dev initialization routines

[Michal H. <ms...@gm...>]

This is update for the original pdfedit_dev_init function signature
which should help to make further chnages easier without API breakage.

Changes to previous version:
* pdfedit_dev_init takes argc and argv parameters so that initialization
  code can use them without any special effort from application side.
  This is not implemented yet, but we are _prepared_ for such an issue.
* pdfedit_dev_init also takes pdfedit_dev_init structure as parameter
  rahter than cfgFileName and fontDir. This means that we can add more
  input parameters without API breakage as well.
* pdfedit_dev_init calls has to be moved before command line
  manipulation in gui/main.cc, because we want to handle pdfedit-dev
  parameters before application can mess with them.
* initialization separated to parameters and xpdf done in separate
  function
* return value of pdfedit_dev_init is -errno rahter than -1 which
  doesn't give enough information about cause

Update patch is attached.
