There were 4 macros in ocsp.h that have not worked since 1.1.0 because
they attempt to access the internals of an opaque structure.

For OCSP_REQUEST_sign() applications should use OCSP_request_sign() instead.
For OCSP_BASICRESP_sign() applications should use OCSP_basic_sign() instead.
For OCSP_REQUEST_verify() applications should use OCSP_request_verify()
instead.
For OCSP_BASICRESP_verify() applications should use OCSP_basic_verify()
instead.

In OpenSSL pre 1.1.0, 'openssl x509 -CAkeyformat engine' was possible
and supported.  In 1.1.0, a small typo ('F' instead of 'f') removed
that possibility.  This restores the pre 1.1.0 behavior.

This doesn't rate as a CVE because:

* For the constant time code, it requires a significant number of signatures

The eventfd syscall is deprecated and is not available on aarch64, causing
build to fail:

    engines/e_afalg.c: In function 'eventfd':
    engines/e_afalg.c:108:20: error: '__NR_eventfd' undeclared (first use in this function)
         return syscall(__NR_eventfd, n);
                        ^

Instead, switch to the newer eventfd2 syscall, which is supposed to be
supported by all architectures.

This kind of issues would be avoided by simply using the eventfd(2)
wrapper from the libc, but there must be subtle reasons not to...

Tested on a aarch64 system running OpenSUSE Leap 42.1 (gcc118 from
https://cfarm.tetaneutral.net/machines/list/ ) and also cross-compiling
for aarch64 with LEDE (kernel 4.9).

This properly fixes #1685.

We currently increment the SSL_CTX stats.sess_accept field in
tls_setup_handshake(), which is invoked from the state machine well
before ClientHello processing would have had a chance to switch
the SSL_CTX attached to the SSL object due to a provided SNI value.
However, stats.sess_accept_good is incremented in tls_finish_handshake(),
and uses the s->ctx.stats field (i.e., the new SSL_CTX that was switched
to as a result of SNI processing).  This leads to the confusing
(nonsensical) situation where stats.sess_accept_good is larger than
stats.sess_accept, as the "sess_accept" value was counted on the
s->session_ctx.

In order to provide some more useful numbers, increment
s->ctx.stats.sess_accept after SNI processing if the SNI processing
changed s->ctx to differ from s->session_ctx.  To preserve the
property that any given accept is counted only once, make the
corresponding decrement to s->session_ctx.stats.sess_accept when
doing so.

For client SSL objects and before any callbacks have had a chance
to be called, we can write the stats accesses using the session_ctx,
which makes sense given that these values are all prefixed with
"sess_".

For servers after a client_hello or servername callback has been
called, retain the existing behavior of modifying the statistics
for the current (non-session) context.  This has some value,
in that it allows the statistics to be viewed on a per-vhost level.
