Global polishing, some bugs corrected, dynamic allocation used instead

of fixed length static buffers in many places.
	* etags.c (FILEPOS, GET_CHARNO, GET_FILEPOS, max, LINENO): Deleted.
	(append_to_tagfile, typedefs, typedefs_and_cplusplus,
	 constantypedefs, update, vgrind_style, no_warnings,
	 cxref_style, cplusplus, noindentypedefs): Were int, now logical.
	(permit_duplicates): Was a var, now a #define.
	(filename_lb): Was global, now local to main.
	(main): Open the tag file when in cxref mode.
	Use a BUFSIZ size buffer for making the shell commands.
	Look at the return value from the system routine.
	Exit when cannot open the tag file.
	(process_file): Open the file and pass the FILE* to find_entries.
	(find_entries): Now void, because does not open the file itself.
	(pfnote): Recovering from lack of memory does not work.  Removed.
	Use savenstr and simplify the code.
	(free_tree): Only free the name space if node is named.
	(structtag): Now a pointer, not a fixed length array of chars.
	(consider_token): Don't take a token as argument.  Use savenstr
	when saving a tag in structtag.  Callers changed.
	(TOKEN): Structure changed.  Now used only in C_entries.
	(TOKEN_SAVED_P, SAVE_TOKEN, RESTORE_TOKEN): Deleted.
	(C_entries): nameb and savenameb deleted.  Use dinamic allocation.
	(pfcnt): Deleted.  Users updated.
	(getit, Asm_labels, Pascal_functions, L_getit, get_scheme,
	 TEX_getit, prolog_getit): Use dinamic allocation for storing
	the tag instead of a fixed size buffer.
