Avoid unnecessary MSYS2 conversion of some arguments

Fixes #4740

The MSYS2 run-time convert arguments that look like paths when
executing a program unless that application is linked with the MSYS
run-time.  The exact conversion rules are listed here:

    http://www.mingw.org/wiki/Posix_path_conversion

With the built-in configurations (all having names starting with
"mingw"), the openssl application is not linked with the MSYS2
run-time, and therefore, it will receive possibly converted arguments
from the process that executes it.  This conversion is fine for normal
path arguments, but it happens that some arguments to the openssl
application get converted when they shouldn't.  In one case, it's
arguments like '-passin file:something', and in another, it's a file:
URI (what typically happens is that URIs without an authority
component get converted, 'cause the conversion mechanism doesn't
recognise them as URIs).

To avoid conversion where we don't want it, we simply assign
MSYS2_ARG_CONV_EXCL a pattern to avoid specific conversions.  As a
precaution, we only do this where we obviously need it.

CVE-2017-3736

Reviewed-by: Rich Salz <rsalz@openssl.org>

Fix small but important regression

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.

Fixes #4366

information about the length of the scalar used in ECDSA operations
from a large number (2^32) of signatures.

This doesn't rate as a CVE because:

* For the non-constant time code, there are easier ways to extract
  more information.

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

afalg: Use eventfd2 syscall instead of eventfd

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.

Provide SSL_CTX.stats.sess_accept for switched ctxs

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.

Normalize on session_ctx for stats where possible

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.
