ctype: restore character classification for non-ASCII platforms With commit 4272a0b0fc49a1ac0ceab5c4a365c9f6ab8bf8e2 curl-speficic character classification macros and functions were introduced in curl_ctype.[ch] to avoid dependencies on the locale. This broke curl on non-ASCII, e.g. EBCDIC platforms. This change restores the previous set of character classification macros when CURL_DOES_CONVERSIONS is defined. Closes #2494

URL: fix ASCII dependency in strcpy_url and strlen_url Commit 3c630f9b0af097663a64e5c875c580aa9808a92b partially reverted the changes from commit dd7521bcc1b7a6fcb53c31f9bd1192fcc884bd56 because of the problem that strcpy_url() was modified unilaterally without also modifying strlen_url(). As a consequence strcpy_url() was again depending on ASCII encoding. This change fixes strlen_url() and strcpy_url() in parallel to use a common host-encoding independent criterion for deciding whether an URL character must be %-escaped. Closes #2535
