/**
* _dbus_shell_parse_argv:
*
* Parses a command line into an argument vector, in much the same way
* the shell would, but without many of the expansions the shell would
* perform (variable expansion, globs, operators, filename expansion,
* etc. are not supported). The results are defined to be the same as
* those you would get from a UNIX98 /bin/sh, as long as the input
* contains none of the unsupported shell expansions. If the input
* does contain such expansions, they are passed through
* literally. Free the returned vector with dbus_free_string_array().
*
* @command_line: command line to parse
* @argcp: return location for number of args
* @argvp: return location for array of args
* @error: error information
