    Implement support for ast_channel_queryoption on local channels.  Currently only AST_OPTION_T38_STATE is supported.

    ABE-2229
    Review: https://reviewboard.asterisk.org/r/813/
  ........
  
  Additionally, pass AST_CONTROL_T38_PARAMETERS control frames through generic bridges.  This change appears to have been unintentionally left out of rev 203699.
