cpplib.h: Merge struct cpp_options into struct cpp_reader.

Browse Source 
* cpplib.h: Merge struct cpp_options into struct cpp_reader.
	Reorder struct cpp_options and struct cpp_reader for better
	packing.  Replace CPP_OPTIONS macro with CPP_OPTION which
	takes two args.  Change all 'char' flags to 'unsigned char'.
	Move show_column flag into struct cpp_options.  Don't
	prototype cpp_options_init.
	* cpphash.h, cpperror.c, cppexp.c, cppfiles.c, cpphash.c,
	cppinit.c, cpplex.c, cpplib.c:
	Replace CPP_OPTIONS (pfile)->whatever with
	CPP_OPTION (pfile, whatever), and likewise for
	opts = CPP_OPTIONS (pfile); ... opts->whatever;

	* cppinit.c (merge_include_chains): Take a cpp_reader *.
	Extract CPP_OPTION (pfile, pending) and work with that
	directly.
	(cpp_options_init): Delete.
	(cpp_reader_init): Turn on on-by-default options here.
	Allocate the pending structure here.
	(cl_options, enum opt_code): Define these from the same table,
	kept in a large macro.  Add -fshow-column and -fno-show-column
	options.

	* cpperror.c (v_message): If show_column is off, don't print
	the column number.

	* cppmain.c: Update for new interface.
	* fix-header.c: Likewise.
