The fuzzers are timing out on inputs that spam SSL_CTX_add1_chain_cert
and SSL_CTX_get0_chain_certs. In our current X509* caching
implementation, this can be quadratic. As this is an API fuzzer, not an
actual attack surface, this is not of much interest in itself, but
bounding this will let the fuzzers fuzz faster.

An offset > 2^15 would exceed the range of an addi immediate on ppc64le.
Thus, rather than add the offset after loading the TOC reference, have
different tocloader functions for each (symbol, offset) pair. In this
case, the linker can handle large offsets by changing the value of
foo+offset@toc@ha accordingly.

Additionally, the input to the key schedule function comes from outside

Most importantly, this version of delocate works for ppc64le. It should
also work for x86-64, but will need significant testing to make sure
that it covers all the cases that the previous delocate.go covered.
It's less stringtastic than the old code, however the parser isn't as
nice as I would have liked. I thought that the reason we put up with
AT&T syntax with Intel is so that assembly syntax could be somewhat
consistent across platforms. At least for ppc64le, that does not appear
to be the case.

The only place it is used is EC_KEY_{dup,copy} and no one calls that
function on an EC_KEY with ex_data. This aligns with functions like
RSAPublicKey_dup which do not copy ex_data. The logic is also somewhat
subtle in the face of malloc errors (upstream's PR 3323).
In fact, we'd even changed the function pointer signature from upstream,
so BoringSSL-only code is needed to pass this pointer in anyway. (I
haven't switched it to CRYPTO_EX_unused because there are some callers
which pass in an implementation anyway.)
Note, in upstream, the dup hook is also used for SSL_SESSIONs when those
are duplicated (for TLS 1.2 ticket renewal or TLS 1.3 resumption). Our
interpretation is that callers should treat those SSL_SESSIONs
equivalently to newly-established ones. This avoids every consumer
providing a dup hook and simplifies the interface.
(I've gone ahead and removed the TODO(fork). I don't think we'll be able
to change this API. Maybe introduce a new one, but it may not be worth
it? Then again, this API is atrocious... I've never seen anyone use argl
and argp even.)

This introduces machinery to start embedding the test data files into
the crypto_test binary. Figuring out every CI's test data story is more
trouble than is worth it. The GTest FileTest runner is considerably
different from the old one:
- It returns void and expects failures to use the GTest EXPECT_* and
ASSERT_* macros, rather than ExpectBytesEqual. This is more monkey
work to convert, but ultimately less work to add new tests. I think
it's also valuable for our FileTest and normal test patterns to align
as much as possible. The line number is emitted via SCOPED_TRACE.
- I've intentionally omitted the Error attribute handling, since that
doesn't work very well with the new callback. This means evp_test.cc
will take a little more work to convert, but this is again to keep our
two test patterns aligned.
- The callback takes a std::function rather than a C-style void pointer.
This means we can go nuts with lambdas. It also places the path first
so clang-format doesn't go nuts.

Instead of a script which generates macros, emit static inlines in
individual header (or C files). This solves a few issues with the
original setup:
- The documentation was off. We match the documentation now.
- The stack macros did not check constness; see some of the fixes in
crypto/x509.
- Type errors did not look like usual type errors.
- Any type which participated in STACK_OF had to be made partially
public. This allows stack types to be defined an internal header or
even an individual file.
- One could not pass sk_FOO_free into something which expects a function
pointer.
