Try to set the ASN.1 parameters for CMS encryption even if the IV
length is zero as the underlying cipher should still set the type.
This will correctly result in errors if an attempt is made to use
an unsupported cipher type.

If the application has limited the size of the async pool using
ASYNC_init_thread() then we could run out of jobs while trying to start a
libssl io operation. However libssl was failing to handle this and treating
it like a fatal error. It should not be fatal...we just need to retry when
there are jobs available again.

This demystifies two for-loops that do nothing. They were used to write
the ladder in a unified way. Now that the ladder is otherwise commented,
remove the dead loops.

list -disabled was checking OPENSSL_NO_SSL/OPENSSL_NO_TLS, which are
not used to disable SSL/TLS respectively.
Building with these macros wrongly show as SSL/TLS disabled, hence
removing this code.

The name length limit check in x509_name_ex_d2i() includes
the containing structure as well as the actual X509_NAME. This will
cause large CRLs to be rejected.
Fix by limiting the length passed to ASN1_item_ex_d2i() which will
then return an error if the passed X509_NAME exceeds the length.

The old BIO_accept() function can encounter errors during malloc. We need
to ensure we properly clean up if that occurs.
GH Issue #817
Reviewed-by: Richard Levitte <levitte@openssl.org>
The init_client() function in the apps sets up the client connection. It
may try multiple addresses until it finds one that works. We should clear
the error queue if we eventually get a successful connection because
otherwise we get stale errors hanging around. This can cause problems in
subsequent calls to SSL_get_error(), i.e. non-fatal NBIO events appear as
fatal.

Some non-Gnu compilers interpret -E -P combination differently.
some prioritize -E over -P, others -P over -E (in which case .i
file is generated and sometimes truncated because of redirection).

Also add ASN1_ANY tests for 0, 1 and -1.

Only treat an ASN1_ANY type as an integer if it has the V_ASN1_INTEGER
tag: V_ASN1_NEG_INTEGER is an internal only value which is never used
for on the wire encoding.
