This isn't all of our pointer games by far, but for any code which
doesn't run on armv6, memcpy and pointer cast compile to the same code.
For code with does care about armv6 (do we care?), it'll need a bit more
work. armv6 makes memcpy into a function call.
Ironically, the one platform where C needs its alignment rules is the
one platform that makes it hard to honor C's alignment rules.

POWER8 has hardware transactional memory, which glibc uses to implement
locks. In some cases, taking a lock begins a transaction, wrapping
arbitrary user code (!) until the lock is released. If the transaction
is aborted, everything rewinds and glibc tries again with some other
implementation.
The kernel will abort the transaction in a variety of cases. Notably, on
a syscall, the transaction aborts and the syscall *does not happen*.
https://www.kernel.org/doc/Documentation/powerpc/transactional_memory.txt
Yet, for some reason, although the relevant change does appear to be in
the kernel, the transaction is being rewound with getrandom happening
anyway. This does not work very well.
Instead, only guard the DRBG access with the lock, not CRYPTO_sysrand.
This lock is only used to protect the DRBG from the destructor that
zeros everything.

Most importantly, this version of delocate works for ppc64le. It should

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

AT&T syntax with Intel is so that assembly syntax could be somewhat
consistent across platforms. At least for ppc64le, that does not appear

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.

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.
