(cp-make-translation-table)

(cp-valid-codes): Made defsubsts.
(cp-fix-safe-chars): Deleted.
(mule-diag): Don't require.
(windows-1251, windows-1252): Removed to cyrillic.el/european.el.
(top-level): Check for defined coding system when defining
cp... aliases.  Change w32-add-charset-info test to avoid warning.
(non-iso-charset-alist): Defvar when compiling.
(cp-make-coding-system): Doc fix.
