* Parse input one character at a time.
*
* Input: state - A pointer to a token variable. This is used to
* maintain the parser state between calls. For
* each input stream, you should set up a separate
* state variable and initialize it to dbg_null.
* Pass a pointer to it into this function with each
* character in the input stream. See dbg_test()
* for an example.
* c - The "current" character in the input stream.
*
* Output: A token.
* The token value will change when delimiters are found,
* which indicate a transition between syntactical objects.
* Possible return values are:
*
* dbg_null - The input character was an end-of-line.
* This resets the parser to its initial state
* in preparation for parsing the next line.
* dbg_eof - Same as dbg_null, except that the character
* was an end-of-file.
* dbg_ignore - Returned for whitespace and delimiters.
* These lexical tokens are only of interest
* to the parser.
* dbg_header - Indicates the start of a header line. The
* input character was '[' and was the first on
* the line.
* dbg_timestamp - Indicates that the input character was part
* of a header timestamp.
* dbg_level - Indicates that the input character was part
* of the debug-level value in the header.
* dbg_sourcefile - Indicates that the input character was part
* of the sourcefile name in the header.
* dbg_function - Indicates that the input character was part
* of the function name in the header.
* dbg_lineno - Indicates that the input character was part
* of the DEBUG call line number in the header.
* dbg_message - Indicates that the input character was part
* of the DEBUG message text.
