GH: #1908
In order to minimize dependency on assembler version a number of
post-SSE2 instructions are encoded manually. But in order to simplify
the procedure only register operands are considered. Non-register
operands are passed down to assembler. Module in question uses pshufb
with memory operands, and old [GNU] assembler can't handle it.
Fortunately in this case it's possible skip just the problematic
segment without skipping SSSE3 support altogether.

When configured no-dso, there are no DSO_{whatever} macros defined.
Therefore, before checking those, you have to check if OPENSSL_NO_DSO
is defined.

- the pod path hadn't been changed with the directory layout change
- apparently, pod2html doesn't add ".html" at the end of links, making
them useless, so we need to fix that
With thanks for the report to Michel <michel.sales@free.fr>

The test loops through all the ciphers, attempting to test each one in turn.
However version negotiation happens before cipher selection, so with TLSv1.3
switched on if we use a non-TLSv1.3 compatible cipher suite we get "no
share cipher".

Now that we can link specifically with static libraries, the immediate
need to split ppccap.c (and eventually other *cap.c files) is no more.

This is a skin deep change, which simply renames most places where we talk
about curves in a TLS context to groups. This is because TLS1.3 has renamed
the extension, and it can now include DH groups too. We still only support
curves, but this rename should pave the way for a future extension for DH
groups.

Very simply, support having the .a extension to denote depending on
static libraries. Note that this is not supported on native Windows
when building shared libraries, as there is not static library then,
just an import library with the same name.

Instead of enumerating exactly those files in test/ that include
../ssl/ssl_locl.h, assume they all do.

This is done by taking one vector, "corrupting" last bit of the

Don't set choice selector on parse failure: this can pass unexpected
values to the choice callback. Instead free up partial structure
directly.

Some of stone-age assembler can't cope with r0 in address. It's actually
sensible thing to do, because r0 is shunted to 0 in address arithmetic
and by refusing r0 assembler effectively makes you understand that.

We can end up with a NULL SSL_METHOD function if a method has been
disabled. If that happens then we shouldn't call vent->smeth().
