Don't define stacks in C source files: it causes warnings

Applications wishing to include their own stacks now just need to include

DEFINE_STACK_OF(foo)

Change DECLARE_STACK_OF into inline functions. This avoids the need for

If there's a failure allocating md_data, the destination pctx will have
a shared pointer with the source EVP_MD_CTX, which will lead to problems
when either the source or the destination is freed.

The protocol selection code is now consolidated in a few consecutive
short functions in a single file and is table driven.  Protocol-specific
constraints that influence negotiation are moved into the flags
field of the method structure.  The same protocol version constraints
are now applied in all code paths.  It is now much easier to add
new protocol versions without reworking the protocol selection
logic.

In the presence of "holes" in the list of enabled client protocols
we no longer select client protocols below the hole based on a
subset of the constraints and then fail shortly after when it is
found that these don't meet the remaining constraints (suiteb, FIPS,
security level, ...).  Ideally, with the new min/max controls users
will be less likely to create "holes" in the first place.

SIZE_MAX is a great macro, and does unfortunately not exist everywhere.
Since we check against half of it, using bitwise shift to calculate the
value of half SIZE_MAX should be safe enough.

If DSA parameters are absent return -1 (for unknown) in DSA_security_bits.

If parameters are absent when a certificate is set in an SSL/SSL_CTX
structure this will reject the certificate by default. This will cause DSA
certificates which omit parameters to be rejected but that is never (?)
done in practice.

Previous versions of OpenSSL had the max size limit for a CertificateRequest
message as |s->max_cert_list|. Previously master had it to be
SSL3_RT_MAX_PLAIN_LENGTH. However these messages can get quite long if a
server is configured with a long list of acceptable CA names. Therefore
the size limit has been increased to be consistent with previous versions.
