Test reading/writing to an SSL object after a fatal error has been
detected. This CVE only affected 1.0.2, but we should add it to other
branches for completeness.

The check_fatal macro is supposed to only be called if we are already
expecting to be in the fatal state. The macro asserts that we are and
puts us into the fatal state if not.
This issue combined with the problem fixed in the previous commit meant
that the fuzzer detected a crash at a point in the processing when we
should have already been in the fatal state.

The recent SSL error overhaul left a case where an error occurs but
SSLfatal() is not called.

The most likely explanation for us ending up at this point in the code
is that we were called by the user application incorrectly - so use an
appropriate error code.

Sometimes at the top level of the state machine code we know we are

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).

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.

and the new SSL_OP_PRIORITIZE_CHACHA_FOR_MOBILE option is used,
then reprioritize ChaCha above everything else. This way, A matching
ChaCha cipher will be selected if there is a match. If no ChaCha ciphers

Multi-prime RSA security is not determined by modulus length alone, but
depends even on number of primes. Too many primes render security
inadequate, but there is no common amount of primes or common factors'
length that provide equivalent secuity promise as two-prime for given
modulus length. Maximum amount of permitted primes is determined
according to following table.

Commit 30bea14be6 converted bntest.c to the new TEST framework.
Unfortunately a missing "goto err" means that the lshift tests skip
the actual bit that tests them. Replacing the "goto err" reveals that
the conversion also broke the tests. This adds back the missing "goto err"
and fixes the tests.

observation that AVX512 code paths can negatively affect overall
Skylake-X system performance. Since we are likely to suppress
AVX512F capability flag [at least on Skylake-X], conversion serves
as kind of "investment protection".
