As a precursor to removing the code entirely later, disable the protocol
by default. Callers must use SSL_CTX_set_min_version to enable it.
This change also makes SSLv3_method *not* enable SSL 3.0. Normally
version-specific methods set the minimum and maximum version to their
version. SSLv3_method leaves the minimum at the default, so we will
treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.
This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in
any no-ssl3 build paths in consumers which should provide a convenient
hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3
existed in older versions of OpenSSL, so in principle one may encounter
an OpenSSL with the same settings.)

Playing games with sections was a little overly clever and relied on the

This fixes two issues in clang.
- clang emits callq instead of call.
- clang emits .cfi_endproc after .size for the dummy functions. This
causes it to get confused as there is no matching .cfi_startproc.
Don't bother trying to omit the dummy functions.
Alas, clang seems to compile the DEFINE_METHOD_FUNCTION hooks in a way
that brings the .rel.ro back AND isn't honoring the noinline. We'll
probably need to go back to the original CL's setup there.

This only works at TLS 1.2 and above as, before TLS 1.2, there is no way
to advertise support for Ed25519 or negotiate the correct signature
algorithm. Add tests for this accordingly.
For now, this is disabled by default on the verifying side but may be
enabled per SSL_CTX. Notably, projects like Chromium which use an
external verifier may need changes elsewhere before they can enable it.
(On the signing side, we can assume that if the caller gave us an
Ed25519 certificate, they mean for us to use it.)

(Thanks to Sam Panzer for the patch.)
At least some linkers will drop constructor functions if no symbols from
that translation unit are used elsewhere in the program. On POWER, since
the cached capability value isn't a global in crypto.o (like other
platforms), the constructor function is getting discarded.
The C++11 spec says (3.6.2, paragraph 4):
It is implementation-defined whether the dynamic initialization of a
non-local variable with static storage duration is done before the
first statement of main. If the initialization is deferred to some
point in time after the first statement of main, it shall occur
before the first odr-use (3.2) of any function or variable defined
in the same translation unit as the variable to be initialized.
Compilers appear to interpret that to mean they are allowed to drop
(i.e. indefinitely defer) constructors that occur in translation units
that are never used, so they can avoid initializing some part of a
library if it's dropped on the floor.
This change makes the hardware capability value for POWER a global in
crypto.c, which should prevent the constructor function from being
ignored.
