eliminate global global_command variable
* toplev.h, toplev.cc (global_command): Delete.
* parse.h, oct-parse.in.yy (octave_parser::stmt_list):
New member variable.
(octave_parser::octave_parser): Initialize it to zero.
(octave_parser:~octave_parser): Delete it.
(octave_parser::reset): Delete it and set it to zero.
* toplev.cc (main_loop): Use curr_parser->stmt_list instead of
global_command.
* input.cc (get_debug_input): Likewise.
* oct-parse.in.yy (eval_string, parse_fcn_file): Likewise.
(ABORT_PARSE): Don't set global_command to zero.
(input): Set curr_parser->stmt_list instead of global_command.
