When building on Unix, there are times when the 'EX_LIB' MINFO variable
contains valuable information.  Make sure to take care of it.

fixrules in util/pl/unix.pl was previously changed with a simpler fix of
rules, with a comment claiming that's compatible with -j.  Unfortunately,
this breaks multiline rules and doesn't change anything for single line
rules.  While at it, do not prefix pure echo lines with a 'cd $(TEST_D) &&',
as that's rather silly.

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.
