Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.
Likewise, move crypto/foo/footest.c to test/footest.c, instead of
symlinking it there.

RFC5915 requires the use of the I2OSP primitive as defined in RFC3447
for storing an EC Private Key. This converts the private key into an
OCTETSTRING and retains any leading zeros. This commit ensures that those
leading zeros are present if required.

The FAQ says this:
After the release of OpenSSL 1.0.0 the versioning scheme changed. Letter
releases (e.g. 1.0.1a) can only contain bug and security fixes and no
new features. Minor releases change the last number (e.g. 1.0.2) and
can contain new features that retain binary compatibility. Changes to
the middle number are considered major releases and neither source nor
binary compatibility is guaranteed.
With such a scheme (and with the thinking that it's nice if the shared
library version stays on track with the OpenSSL version), it's rather
futile to keep the minor release number in the shared library version.
The deed already done with OpenSSL 1.0.x can't be changed, but with
1.x.y, x=1 and on, 1.x as shared library version is sufficient.

Remove the combine option. This was used for compatibility with some
non standard behaviour in ancient versions of OpenSSL: specifically
the X509_ATTRIBUTE and DSAPublicKey handling. Since these have now
been revised it is no longer needed.

DSA public keys could exist in two forms: a single Integer type or a
SEQUENCE containing the parameters and public key with a field called
"write_params" deciding which form to use. These forms are non standard
and were only used by functions containing "DSAPublicKey" in the name.
Simplify code to only use the parameter form and encode the public key
component directly in the DSA public key method.

The X509_ATTRIBUTE structure includes a hack to tolerate malformed
attributes that encode as the type instead of SET OF type. This form
is never created by OpenSSL and shouldn't be needed any more.

The justification for RAND_pseudo_bytes is somewhat dubious, and the reality
is that it is frequently being misused. RAND_bytes and RAND_pseudo_bytes in
the default implementation both end up calling ssleay_rand_bytes. Both may
return -1 in an error condition. If there is insufficient entropy then
both will return 0, but RAND_bytes will additionally add an error to the
error queue. They both return 1 on success.
Therefore the fundamental difference between the two is that one will add an
error to the error queue with insufficient entory whilst the other will not.
Frequently there are constructions of this form:
if(RAND_pseudo_bytes(...) <= 1)
goto err;
In the above form insufficient entropy is treated as an error anyway, so
RAND_bytes is probably the better form to use.
This form is also seen:
if(!RAND_pseudo_bytes(...))
goto err;
This is technically not correct at all since a -1 return value is
incorrectly handled - but this form will also treat insufficient entropy as
an error.
Within libssl it is required that you have correctly seeded your entropy
pool and so there seems little benefit in using RAND_pseudo_bytes.
Similarly in libcrypto many operations also require a correctly seeded
entropy pool and so in most interesting cases you would be better off
using RAND_bytes anyway. There is a significant risk of RAND_pseudo_bytes
being incorrectly used in scenarios where security can be compromised by
insufficient entropy.
If you are not using the default implementation, then most engines use the
same function to implement RAND_bytes and RAND_pseudo_bytes in any case.
Given its misuse, limited benefit, and potential to compromise security,
RAND_pseudo_bytes has been deprecated.

Disable loop checking when we retry verification with an alternative path.
This fixes the case where an intermediate CA is explicitly trusted and part

the untrusted CA can be replaced by the explicitly trusted case and
