/* Some general info on the function of the generated code and how they work
   for .library modules (TODO: add docs for other module types):

   The code in this file will write out the inittable, the function table,
   the InitLib, OpenLib, CloseLib and ExpungeLib function.
   InitLib will call the functions in the ADD2INIT symbolset.
   OpenLib will call the functions in the ADD2OPENLIB symbolset.
   CloseLib will call the functions in the ADD2CLOSELIB symbolset.
   ExpungeLib will call the fucntions in the ADD2EXIT symbolset.

   Currently 2 types of libraries are supported: 1 libbase and a per-opener
   libbase.
   * For 1 libbase the libbase is initialized once in InitLib and
     then returned for each call to OpenLib. OpenLib and CloseLib keep track
     of the times the libraries is still open; if it is 0 the library may be
     expunged.
   * The per-opener libbase will create a new libbase for each call to OpenLib
     After InitLib has called the ADD2INIT functions the fields in the root
     libbase may have been initialized to a certain value. These value are
     copied in the newly generated libbase and then the ADD2OPENLIB functions
     are called with the new libbase.
     A per-opener libbase is indicated by the OPTION_DUPBASE flag in cfg->options.
     Currently, a task memory slot is used to store the libbase when a function
     of the library is entered. With proper support from the compiler this could
     be changed to use a reserved register - probably increasing speed. This
     could be implemented later on without breaking backwards compatibility.
     Special provision has been taken to restore the state of the memory slot
     after CloseLib to what it was when OpenLib is called. This is to handle the
     case properly where the library is used both in the parent and child
     of a Task run with RunCommand().
