Make possible variant SONAMEs and symbol versions

This small change in the Unix template and shared library build
scripts enables building "variant" shared libraries.  A "variant"
shared library has a non-default SONAME, and non default symbol
versions.  This makes it possible to build (say) an OpenSSL 1.1.0
library that can coexist without conflict in the same process address
space as the system's default OpenSSL library which may be OpenSSL
1.0.2.

Such "variant" shared libraries make it possible to link applications
against a custom OpenSSL library installed in /opt/openssl/1.1 or
similar location, and not risk conflict with an indirectly loaded
OpenSSL runtime that is required by some other dependency.

Variant shared libraries have been fully tested under Linux, and
build successfully on MacOS/X producing variant DYLD names.  MacOS/X
Darwin has no symbol versioning, but has a non-flat library namespace.
Variant libraries may therefore support multiple OpenSSL libraries
in the same address space also with MacOS/X, despite lack of symbol
versions, but this has not been verified.

Variant shared libraries are optional and off by default.

Avoid unnecessary MSYS2 conversion of some arguments

Fixes #4740

The MSYS2 run-time convert arguments that look like paths when
executing a program unless that application is linked with the MSYS
run-time. The exact conversion rules are listed here:

    http://www.mingw.org/wiki/Posix_path_conversion

With the built-in configurations (all having names starting with
"mingw"), the openssl application is not linked with the MSYS2
run-time, and therefore, it will receive possibly converted arguments
from the process that executes it. This conversion is fine for normal
path arguments, but it happens that some arguments to the openssl
application get converted when they shouldn't. In one case, it's
arguments like '-passin file:something', and in another, it's a file:
URI (what typically happens is that URIs without an authority
component get converted, 'cause the conversion mechanism doesn't
recognise them as URIs).

To avoid conversion where we don't want it, we simply assign
MSYS2_ARG_CONV_EXCL a pattern to avoid specific conversions. As a
precaution, we only do this where we obviously need it.

Don't use strcasecmp and strncasecmp for IA5 strings

The functions strcasecmp() and strncasecmp() will use locale specific rules
when performing comparison. This could cause some problems in certain
locales. For example in the Turkish locale an 'I' character is not the
uppercase version of 'i'. However IA5 strings should not use locale specific
rules, i.e. for an IA5 string 'I' is uppercase 'i' even if using the
Turkish locale.

This fixes a bug in name constraints checking reported by Thomas Pornin
(NCCGroup).

This is not considered a security issue because it would require both a
Turkish locale (or other locale with similar issues) and malfeasance by
a trusted name-constrained CA for a certificate to pass name constraints
in error. The constraints also have to be for excluded sub-trees which are
extremely rare. Failure to match permitted subtrees is a bug, not a
vulnerability.

asn1_item_embed_new(): don't free an embedded item

The previous change with this intention didn't quite do it.  An
embedded item must not be freed itself, but might potentially contain
non-embedded elements, which must be freed.

So instead of calling ASN1_item_ex_free(), where we can't pass the
embed flag, we call asn1_item_embed_free() directly.

This changes asn1_item_embed_free() from being a static function to
being a private non-static function.

Don't make any changes to the lhash structure if we are going to fail

The lhash expand() function can fail if realloc fails. The previous
implementation made changes to the structure and then attempted to do a
realloc. If the realloc failed then it attempted to undo the changes it
had just made. Unfortunately changes to lh->p were not undone correctly,
ultimately causing subsequent expand() calls to increment num_nodes to a
value higher than num_alloc_nodes, which can cause out-of-bounds reads/
writes. This is not considered a security issue because an attacker cannot
cause realloc to fail.

This commit moves the realloc call to near the beginning of the function
before any other changes are made to the lhash structure. That way if a
failure occurs we can immediately fail without having to undo anything.

Allow DH_set0_key with only private key.

The pub_key field for DH isn't actually used in DH_compute_key at all.
(Note the peer public key is passed in as as BIGNUM.) It's mostly there
so the caller may extract it from DH_generate_key. It doesn't
particularly need to be present if filling in a DH from external
parameters.

The check in DH_set0_key conflicts with adding OpenSSL 1.1.0 to Node.
Their public API is a thin wrapper over the old OpenSSL one:
https://nodejs.org/api/crypto.html#crypto_class_diffiehellman

They have separate setPrivateKey and setPublicKey methods, so the public
key may be set last or not at all. In 1.0.2, either worked fine since
operations on DH objects generally didn't use the public key.  (Like
with OpenSSL, Node's setPublicKey method is also largely a no-op, but so
it goes.) In 1.1.0, DH_set0_key prevents create a private-key-only DH
object.
