Refactor code generation options
Most options to the code generation pass are passed through the process dictionary. At the same time, an Erule or Erules argument is passed to most code generation functions. The Erule argument is only an atom indicating the encoding rules ('ber', 'per', or 'uper'). Introduce a new record #gen{} to contain code generation options and parameters. Pass it as the Erule argument (renaming it to Gen in functions that we will have to touch anyway). In this commit, eliminate the use of the variable 'encoding_options' in the process dictionary.
