If OpenSSL is configured with no-tlsext then ssl_get_prev_session can read
past the end of the ClientHello message if the session_id length in the
ClientHello is invalid. This should not cause any security issues since the
underlying buffer is 16k in size. It should never be possible to overrun by
that many bytes.
This is probably made redundant by the previous commit - but you can never be
too careful.
With thanks to Qinghao Tang for reporting this issue.

The ClientHello processing is insufficiently rigorous in its checks to make
sure that we don't read past the end of the message. This does not have
security implications due to the size of the underlying buffer - but still
needs to be fixed.

While *pval is usually a pointer in rare circumstances it can be a long
value. One some platforms (e.g. WIN64) where
sizeof(long) < sizeof(ASN1_VALUE *) this will write past the field.
*pval is initialised correctly in the rest of ASN1_item_ex_new so setting it
to NULL is unecessary anyway.

Since source reformat, we ended up with some error reason string
definitions that spanned two lines. That in itself is fine, but we
sometimes edited them to provide better strings than what could be
automatically determined from the reason macro, for example:
{ERR_REASON(SSL_R_NO_GOST_CERTIFICATE_SENT_BY_PEER),
"Peer haven't sent GOST certificate, required for selected ciphersuite"},
However, mkerr.pl didn't treat those two-line definitions right, and
they ended up being retranslated to whatever the macro name would
indicate, for example:
{ERR_REASON(SSL_R_NO_GOST_CERTIFICATE_SENT_BY_PEER),
"No gost certificate sent by peer"},
Clearly not what we wanted. This change fixes this problem.

We use GNU statement expressions in crypto/md32_common.h, surrounded
by checks that GNU C is indeed used to compile. It seems that clang,
at least on Linux, pretends to be GNU C, therefore finds the statement
expressions and then warns about them.
The solution is to have clang be quiet about it.

ARM has optimized Cortex-A5x pipeline to favour pairs of complementary
AES instructions. While modified code improves performance of post-r0p0
Cortex-A53 performance by >40% (for CBC decrypt and CTR), it hurts
original r0p0. We favour later revisions, because one can't prevent
future from coming. Improvement on post-r0p0 Cortex-A57 exceeds 50%,
while new code is not slower on r0p0, or Apple A7 for that matter.

This engine is for VMS only, and isn't really part of the core OpenSSL
but rather a side project of its own that just happens to have tagged
along for a long time. The reasons why it has remained within the
OpenSSL source are long lost in history, and there not being any real
reason for it to remain here, it's time for it to move out.
This side project will appear as a project in its own right, the
location of which will be announced later on.

With no more symlinks, there's no need for those variables, or the links

top Makefile.
Also, removed METHTEST from test/Makefile. It looks like an old test that's
