Probably worth having actual test vectors for these, rather than
checking our code against itself. Additionally, small negative numbers
have, in the past been valuable test vectors (see long comment in
point_add from OpenSSL's ecp_nistp521.c).

The Bluetooth Mesh spec uses both apparently. Also extract a pile of
test vectors from that document (thanks to Kyle Lund for showing me
which to extract).

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.

This is a fairly shallow conversion because of the somewhat screwy Error
lines in the test which may target random functions like
EVP_PKEY_CTX_set_signature_md. We probably should revise this, perhaps
moving those to normal tests and leaving error codes to the core
operation itself.

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.
