If we failed to fetch an EVP_KEYMGMT then we were falling back to legacy.
This is because some algorithms (such as MACs and KDFs used via an old
style EVP_PKEY) have not been transferred to providers.
Unfortunately this means that you cannot stop some algorithms from being
used by not loading the provider.
For example if you wanted to prevent RSA from being used, you might expect
to just not load any providers that make it available. Unfortunately that
doesn't work because we simply fall back to legacy if we fail to fetch
the EVP_KEYMGMT.
Instead we should fail *unless* the key type is one of those legacy key
types that we have not transferred.

PR#6975 added the ability to our test framework to have common options to
all tests. For example providing the option "-test 5" to one of our test
programs will just run test number 5. This can be useful when debugging
tests.
Unforuntately this does not work well for a number of tests. In particular
those tests that call test_get_argument() without first skipping over these
common test options will not get the expected value. Some tests did this
correctly but a large number did not.
A helper function is introduced, test_skip_common_options(), to make this
easier for those tests which do not have their own specialised test option
handling, but yet still need to call test_get_argument(). This function
call is then added to all those tests that need it.

Fixes#10438
issue found by clusterfuzz/ossfuzz
The dest was getting a copy of the src structure which contained a pointer that should point to an offset inside itself - because of the copy it was pointing to the original structure.
The setup for a ctx is mainly done by the initkey method in the PROV_CIPHER_HW structure. Because of this it makes sense that the structure should also contain a copyctx method that is use to resolve any pointers that need to be setup.
A dup_ctx has been added to the cipher_enc tests in evp_test. It does a dup after setup and then frees the original ctx. This detects any floating pointers in the duplicated context that were pointing back to the freed ctx.

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

Compiling OpenSSL code with MSVC and /W4 results in a number of warnings.
One category of warnings is particularly interesting - C4701 (potentially

that there's a code path which results in uninitialized variables being used
or returned. Depending on compiler, its options, OS, values in registers
and/or stack, the results can be nondeterministic. Cases like this are very
hard to debug so it's rational to fix these issues.
This patch contains a set of trivial fixes for all the C4701 warnings (just
initializing variables to 0 or NULL or appropriate error code) to make sure
that deterministic values will be returned from all the execution paths.

After the finale, the "real" final part. :) Do a recursive grep with
"-B1 -w [a-zA-Z0-9_]*_free" to see if any of the preceeding lines are
an "if NULL" check that can be removed.

Rather than making include/openssl/foo.h a symlink to
crypto/foo/foo.h, this change moves the file to include/openssl/foo.h
once and for all.
Likewise, move crypto/foo/footest.c to test/footest.c, instead of
symlinking it there.
