We're a far cry from the good old days when we just read from /dev/urandom
without any fuss...
In particular, the threading logic is slightly non-trivial and probably worth
some basic sanity checks. Also write a fork-safety test, and test the
fork-unsafe-buffering path.
The last one is less useful right now, since fork-unsafe-buffering is a no-op
with RDRAND enabled (although we do have an SDE bot...), but it's probably
worth exercising the code in

using Make and output directories for perlasm are no longer created
before Perl is run. Additionally, if the output directory doesn't exist,
the perlasm scripts seem to output to stdout instead.

I realized looking at the sigalgs parser that I messed up the
space-splitting logic slightly. If the CPU features are "foo bar baz",
it would not parse "baz". This doesn't particular matter (the last one
is "crc32"), but better to parse it correctly.
Fix this and add a unit test. While I'm here, may as well add a fuzzer

This fixes uninitialized memory read reported by Nick Mathewson in
https://github.com/openssl/openssl/issues/6347.
It imports the memset from upstream's 2c739f72e5236a8e0c351c00047c77083dcdb77f,
but I believe that fix is incorrect and instead RC4 shouldn't be allowed in
this context. See
https://github.com/openssl/openssl/pull/6603#issuecomment-413066462 for
details.
Update-Note: Decoding a password-protected PEM block with RC4 will, rather than
derive garbage from uninitialized memory, simply fail. Trying to encode a
password-protect PEM block with an unsupported cipher will also fail, rather
than output garbage (e.g. tag-less AES-GCM).

We currently write a mix of "if (FOO)" and "if(FOO)". While the former looks
more like a usual language, CMake believes everything, even "if" and "else", is
just a really really funny function call (a "command").
We should pick something for consistency. Upstream CMake writes "if(FOO)", so
go with that one.

This imports upstream's scrypt implementation, though it's been heavily
revised. I lost track of words vs. blocks vs. bigger blocks too many
times in the original code and introduced a typedef for the fixed-width
Salsa20 blocks. The downside is going from bytes to blocks is a bit
trickier, so I took advantage of our little-endian assumption.
This also adds an missing check for N < 2^32. Upstream's code is making
this assumption in Integerify. I'll send that change back upstream. I've
also removed the weird edge case where a NULL out_key parameter means to
validate N/r/p against max_mem and nothing else. That's just in there to
get a different error code out of their PKCS#12 code.
Performance-wise, the cleanup appears to be the same (up to what little
precision I was able to get here), but an optimization to use bitwise
AND rather than modulus makes us measurably faster. Though scrypt isn't
a fast operation to begin with, so hopefully it isn't anyone's
bottleneck.
This CL does not route scrypt up to the PKCS#12 code, though we could
write our own version of that if we need to later.

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.

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.
