New header file, include/openssl/macros.h, which contains diverse
useful macros that we use elsewhere.
We also add the new macro OPENSSL_FUNC, which is an alias for
__FUNC__, __FUNCTION__, __FUNCSIG or __func__, depending on what the
compiler supports. In the worst case, it's an alias for the string
"(unknown function)".

To deallocate the err_data field and then allocating it again might be
a waste of processing, but may also be a source of errors when memory
is scarce. While we normally tolerate that, the ERR sub-system is an
exception and we need to pay closer attention to how we handle memory.
This adds a new err_data flag, ERR_TXT_IGNORE, which means that even
if there is err_data memory allocated, its contents should be ignored.
Deallocation of the err_data field is much more selective, aand should
only happen when ERR_free_state() is called.

Implement the GNU C library's random(3) pseudorandom number generator.
The algorithm is described: https://www.mscs.dal.ca/~selinger/random/
The rationale is to make the tests repeatable across differing platforms with
different underlying implementations of the random(3) library call.
More specifically: when executing tests with random ordering.

This changes the stanza format used so far. Some test stanza had the
following line, only possible for digests:
Legacy = 1
These have been traded for the following:
Availablein = legacy
That line is globally available in all test stanza and can be used to
tell what providers a certain algorithm may be available in. Only one
provider needs to match, so one might have something like this for
some tests:
Availablein = default fips
This means that one of those providers must be available for the test
stanza to be performed.
If the providers mentioned for a stanza aren't available, the test is
skipped.
If this line isn't used in a stanza, the algorithm is assumed to be
available unconditionally (either by fallback providers, or providers
loaded by the config file).

Public function OSSL_PROVIDER_available() takes a library context and
a provider name, and returns 1 if it's available for use, i.e. if it's
possible to fetch implementations from it, otherwise 0.
Internal function ossl_provider_activated() returns 1 if the given
OSSL_PROVIDER is activated, otherwise 0.
To make this possible, the activation of fallbacks got refactored out
to a separate function, which ended up simplifying the code.

tls_parse_stoc_key_share was generating a new EVP_PKEY public/private
keypair and then overrides it with the server public key, so the
generation was a waste anyway. Instead, it should create a
parameters-only EVP_PKEY.
(This is a consequence of OpenSSL using the same type for empty key,
empty key with key type, empty key with key type + parameters, public
key, and private key. As a result, it's easy to mistakenly mix such
things up, as happened here.)

This function is used to traverse all algorithm implementations for a
given operation type, and execute the given function for each of them.
For each algorithm implementation, a method is created and passed to
the given function, and then freed after that function's return. If
the caller wishes to keep the method for longer, they must call the
appropriate up_ref function on the method, and they must also make
sure to free the passed methods at some point.

functions the EVP_PKEY_CTX is used with.
