Fix rpath-related Linux "test_shlibload" failure.

When libssl and libcrypto are compiled on Linux with "-rpath", but
not "--enable-new-dtags", the RPATH takes precedence over
LD_LIBRARY_PATH, and we end up running with the wrong libraries.
This is resolved by using full (or at least relative, rather than
just the filename to be found on LD_LIBRARY_PATH) paths to the
shared objects.

Windows build: build foo.d after foo.obj

We made the build of foo.obj depend on foo.d, meaning the latter gets
built first.  Unfortunately, the way the compiler works, we are forced
to redirect all output to foo.d, meaning that if the source contains
an error, the build fails without showing those errors.

We therefore remove the dependency and force the build of foo.d to
always happen after build of foo.obj.

Allow parallel install

trouble because to sub-targets (install_dev and install_runtime) try
to install the same shared libraries.  That makes parallel install

This is solved by dividing install_runtime into two parts, one for

install_runtime_libs instead of installing the shared runtime

Only CA certificates can be self-issued

At the bottom of https://tools.ietf.org/html/rfc5280#page-12 and
top of https://tools.ietf.org/html/rfc5280#page-13 (last paragraph
of above https://tools.ietf.org/html/rfc5280#section-3.3), we see:

   This specification covers two classes of certificates: CA
   certificates and end entity certificates.  CA certificates may be
   further divided into three classes: cross-certificates, self-issued
   certificates, and self-signed certificates.  Cross-certificates are
   CA certificates in which the issuer and subject are different
   entities.  Cross-certificates describe a trust relationship between
   the two CAs.  Self-issued certificates are CA certificates in which
   the issuer and subject are the same entity.  Self-issued certificates
   are generated to support changes in policy or operations.  Self-
   signed certificates are self-issued certificates where the digital
   signature may be verified by the public key bound into the
   certificate.  Self-signed certificates are used to convey a public
   key for use to begin certification paths.  End entity certificates
   are issued to subjects that are not authorized to issue certificates.

that the term "self-issued" is only applicable to CAs, not end-entity
certificates.  In https://tools.ietf.org/html/rfc5280#section-4.2.1.9
the description of path length constraints says:

   The pathLenConstraint field is meaningful only if the cA boolean is
   asserted and the key usage extension, if present, asserts the
   keyCertSign bit (Section 4.2.1.3).  In this case, it gives the
   maximum number of non-self-issued intermediate certificates that may
   follow this certificate in a valid certification path.  (Note: The
   last certificate in the certification path is not an intermediate
   certificate, and is not included in this limit.  Usually, the last
   certificate is an end entity certificate, but it can be a CA
   certificate.)

This makes it clear that exclusion of self-issued certificates from
the path length count applies only to some *intermediate* CA
certificates.  A leaf certificate whether it has identical issuer
and subject or whether it is a CA or not is never part of the
intermediate certificate count.  The handling of all leaf certificates
must be the same, in the case of our code to post-increment the
path count by 1, so that we ultimately reach a non-self-issued
intermediate it will be the first one (not zeroth) in the chain
of intermediates.

Implement coordinate blinding for EC_POINT

This commit implements coordinate blinding, i.e., it randomizes the
representative of an elliptic curve point in its equivalence class, for
prime curves implemented through EC_GFp_simple_method,
EC_GFp_mont_method, and EC_GFp_nist_method.

This commit is derived from the patch
https://marc.info/?l=openssl-dev&m=131194808413635 by Billy Brumley.

Coordinate blinding is a generally useful side-channel countermeasure
and is (mostly) free. The function itself takes a few field
multiplicationss, but is usually only necessary at the beginning of a
scalar multiplication (as implemented in the patch). When used this way,
it makes the values that variables take (i.e., field elements in an
algorithm state) unpredictable.

For instance, this mitigates chosen EC point side-channel attacks for
settings such as ECDH and EC private key decryption, for the
aforementioned curves.

For EC_METHODs using different coordinate representations this commit
does nothing, but the corresponding coordinate blinding function can be
easily added in the future to extend these changes to such curves.

More EVP ECC testing: positive and negative

1. For every named curve, two "golden" keypair positive tests.

There is some overlap with existing EVP tests, especially for the NIST
curves (for example, positive testing ECC CDH KATs for NIST curves).

"Golden" here means all the values are independent from OpenSSL's ECC
code. I used sage to calculate them. What comes from OpenSSL is:

1. The OIDs (parsed by tooling)
2. The curve parameters (parsing ecparam output with tooling)

The values inside the PEMs (private keys, public keys) and shared keys
are from sage. The PEMs themselves are the output of asn1parse, with
input taken from sage.

Fix segfault in RSA_free() (and DSA/DH/EC_KEY)

`RSA_free()` and friends are called in case of error from
`RSA_new_method(ENGINE *e)` (or the respective equivalent functions).

For the rest of the description I'll talk about `RSA_*`, but the same
applies for the equivalent `DSA_free()`, `DH_free()`, `EC_KEY_free()`.

If `RSA_new_method()` fails because the engine does not implement the
required method, when `RSA_free(RSA *r)` is called,
`r->meth == NULL` and a segfault happens while checking if
`r->meth->finish` is defined.

This commit fixes this issue by ensuring that `r->meth` is not NULL
before dereferencing it to check for `r->meth->finish`.

Fixes #7102 .

i2d_ASN1_OBJECT(): allocate memory if the user didn't provide a buffer

Since 0.9.7, all i2d_ functions were documented to allocate an output
buffer if the user didn't provide one, under these conditions (from
the 1.0.2 documentation):

    For OpenSSL 0.9.7 and later if B<*out> is B<NULL> memory will be
    allocated for a buffer and the encoded data written to it. In this
    case B<*out> is not incremented and it points to the start of the
    data just written.

i2d_ASN1_OBJECT was found not to do this, and would crash if a NULL
output buffer was provided.
