Param to options conversion.

2019-11-12  Martin Liska  <mliska@suse.cz>

	* common.opt: Remove --param and --param= options.
	* opt-functions.awk: Mark CL_PARAMS for options
	that have Param keyword.
	* opts-common.c (decode_cmdline_options_to_array):
	Replace --param key=value with --param=key=value.
	* opts.c (print_filtered_help): Remove special
	printing of params.
	(print_specific_help): Update title for params.
	(common_handle_option): Do not handle OPT__param.
	opts.h (SET_OPTION_IF_UNSET): New macro.
	* doc/options.texi: Document Param keyword.
