Avoid an overflow in constructing the ServerKeyExchange message

We calculate the size required for the ServerKeyExchange message and then
call BUF_MEM_grow_clean() on the buffer. However we fail to take account of
2 bytes required for the signature algorithm and 2 bytes for the signature

because the buffer is pre-allocated to a large size that means it should be

The default config file sets the certopt value to ca_default. The ca utility
takes that and THEN adds additional options to suppress printing of the

Avoid some undefined pointer arithmetic

Where "p" points to some malloc'd data of SIZE bytes and

"len" here could be from some externally supplied data (e.g. from a TLS

The rules of C pointer arithmetic are such that "p + len" is only well

undefined behaviour.

For example this could cause problems if some malloc implementation

Some compression related functions in libssl have dummy versions to be
used when compiled with no-comp. However those dummy functions were not
being exported on Windows so they are unusable when dynamically linked.

Don't send signature algorithms when client_version is below TLS 1.2.

Per RFC 5246,

    Note: this extension is not meaningful for TLS versions prior to 1.2.
    Clients MUST NOT offer it if they are offering prior versions.
    However, even if clients do offer it, the rules specified in [TLSEXT]
    require servers to ignore extensions they do not understand.

Although second sentence would suggest that there would be no interop
problems in always offering the extension, WebRTC has reported issues
with Bouncy Castle on < TLS 1.2 ClientHellos that still include
signature_algorithms. See also
