  Modified files:
    epan                 tvbuff.c tvbuff.h 
  Log:
  Add a "tvb_ensure_bytes_exist()", which is like "tvb_bytes_exist()" only
  it throws the appropriate exception if the bytes don't exist.  Use it in
  the GIOP and ASN.1 code to check whether the bytes to be copied to a
  buffer exist before allocating the buffer.
  
  Make "check_offset_length_no_exception()" check for an overflow, so that
  it can be used in "tvb_ensure_bytes_exist()" and do all the checking
  that the code "tvb_ensure_bytes_exist()" replaces did.
  
  Make "get_CDR_wchar()" return a "gint", so that if the length octet it
  fetched has a value between 128 and 255, the length can be returned
  correctly.
  
  Fix some comments not to specify the exception thrown by various
  routines that can throw various exceptions.
