Fix the check_fatal macro

The check_fatal macro is supposed to only be called if we are already

Provide an SSLfatal() macro

Typically if a fatal error occurs three things need to happen:

- Put an error on the error queue
- Send an alert
- Put the state machine into the error state

Although all 3 of these things need to be done every time we hit a fatal
error the responsibilities for doing this are distributed throughout the
code. The place where the error goes on the queue, where the alert gets
sent and where the state machine goes into the error state are almost
invariably different. It has been a common pattern to pass alert codes up
and down the stack to get the alert information from the point in the code
where the error is detected to the point in the code where the alert gets
sent.

This commit provides an SSLfatal() macro (backed by an ossl_statem_fatal
function) that does all 3 of the above error tasks. This is largely a drop
in replacement for SSLerr, but takes a couple of extra parameters (the SSL
object, and an alert code).

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.

Add OCSP API test executable

Some of the OCSP APIs (such as the recently added OCSP_resp_get0_signer)
do not really merit inclusion in the ocsp(1) utility, but we should still
have unit tests for them.

For now, only test OCSP_resp_get0_signer(), but it should be easy to
add more tests in the future.

Provide an X509 cert and private key in the test's data directory
to use for signing responses, since constructing those on the fly
is more effort than is needed.

Fix race condition in TLSProxy

Normally TLSProxy waits for the s_server process to finish before
continuing. However in cases where serverconnects > 1 we need to keep the
s_server process around for a later test so we continue immediately. This
means that TAP test output can end up being printed to stdout at the same
time as s_server is printing stuff. This confuses the test runner and can
cause spurious test failures. This commit introduces a small delay in cases
where serverconnects > 1 in order to give s_server enough time to finish
what it was doing before we continue to the next test.
