s_client was dumping session data at the end of the handshake. In TLSv1.3
we don't have session data until receipt of a NewSessionTicket message
which happens post-handshake. Therefore we delay dumping the session data
until that message has arrived if TLSv1.3 has been negotiated.

Internal submodules of libcrypto may require non-public functions from
the EC submodule.
In preparation to use `ec_group_do_inverse_ord()` (from #6116) inside
the SM2 submodule to apply a SCA mitigation on the modular inversion,
this commit moves the `ec_group_do_inverse_ord()` prototype declaration
from the EC-local `crypto/ec/ec_lcl.h` header to the
`crypto/include/internal/ec_int.h` inter-module private header.

This makes AIX build procedure behave more like e.g. Solaris. Most
notably this makes it possible to pass -Wl,-R,'$(LIBRPATH)' at config
time to embed installation destination as library search path into
openssl binary. This doesn't imply that other applications have to be
linked with -bsvr4, they are free to choose whatever appropriate for

AIX treats its shared libraries in unique manner, by placing multiple
shared objects of different versions and bitnesses, into .a file.
So far we have been naively linking with version-less libcrypto|ssl.so,
which poses long-term maintenance problems. One could choose to link
straight with libcrypto.so.X.Y [or libcrypto.X.Y.so], but it would be
inconsistent with the way AIX [or Unix] does things.

The goal is to minimize maintenance burden by eliminating somewhat
obscure platform-specific tweaks that are not viewed as critical for
contemporary applications. This affects Camellia and digest
implementations that rely on md32_common.h, MD4, MD5, SHA1, SHA256.
SHA256 is the only one that can be viewed as critical, but given
the assembly coverage, the omission is considered appropriate.

This extends the recently added ECDSA signature blinding to blind DSA too.
This is based on side channel attacks demonstrated by Keegan Ryan (NCC
Group) for ECDSA which are likely to be able to be applied to DSA.
Normally, as in ECDSA, during signing the signer calculates:
s:= k^-1 * (m + r * priv_key) mod order
In ECDSA, the addition operation above provides a sufficient signal for a
flush+reload attack to derive the private key given sufficient signature
operations.
As a mitigation (based on a suggestion from Keegan) we add blinding to
the operation so that:
s := k^-1 * blind^-1 (blind * m + blind * r * priv_key) mod order
Since this attack is a localhost side channel only no CVE is assigned.
This commit also tweaks the previous ECDSA blinding so that blinding is
only removed at the last possible step.
