Add some more callbacks for root properties (bug #42347).
* graphics.in.h (root prop. errormessage): set read-only and declare custom get
method
* graphics.in.h (root prop. diary, diaryfile, echo, recursionlimit): declare
custom get/set methods
* graphics.cc (root::properties::get_errormessage, set_diary, get_diary,
set_diaryfile, get_diaryfile, set_echo, get_echo, set_recursionlimit,
get_recursionlimit): new methods.
* pager.cc (F__diaryfile__, F__diarystate__): new functions to retrieve diary
info.
* pager.cc: set default value "diary" for diary_file static variable.
* input.cc (F__echostate__): new function to retrieve echo info.
