This has been added to avoid the situation where some host ctype.h functions
return true for characters > 127.  I.e. they are allowing extended ASCII
characters through which then cause problems.  E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably.  Likewise letters with diacritical marks can also cause problems.

If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.

The implementation uses a single table with a bit for each of the defined
classes.  These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set.  They will

least one application protocol specification (HTTP/2) imposes restrictions
on which ciphersuites are usable with that protocol.  Since it is generally
more preferrable to have a successful TLS connection with a default application
protocol than to fail the TLS connection and not be able to have the preferred
application protocol, it is good to give the alpn_select callback information
about the ciphersuite to be used, so that appropriate restrctions can be
enforced in application code.

Accordingly, split the ALPN handling out into a separate tls_handl_alpn()
function akin to tls_handle_status_request(), called from
tls_post_process_client_hello().  This is an alternative to resuscitating
ssl_check_clienthello_tlsext_late(), something of an awkwward name itself.

Although this piece of code will not be compiled at current stage, but
there seems a plan to re-open the 'no-rsa' option in the future so this
should be fixed.

Clear error stack on successful OSSL_STORE_open()

Since OSSL_STORE_open() tries with the 'file' scheme loader first, and
then on the loader implied by the URI if the former fails, the former
leaves an error on the error stack.  This is confusing, so let's clear
the error stack on success.  The implementation uses ERR_set_mark,
ERR_pop_to_mark and ERR_clear_last_mark to make sure caller errors are
preserved as much as possible.

Fixes #4089

Add ERR_clear_last_mark()

This allows callers to set a mark, and then clear it without removing
the errors.  Useful in case an error is encountered that should be
returned up the call stack.
