In [1], section 5.1, an optimised re-encryption process is given. In the

https://boringssl-review.googlesource.com/10522 didn't actually do what
it was supposed to do. In fact, it appears, not paying attention to it,
we've managed to make RSA verify slower than ECDSA verify. Oops.
Did 32000 RSA 2048 verify (same key) operations in 1016746us (31473.0 ops/sec)
Did 5525 RSA 2048 verify (fresh key) operations in 1067209us (5177.1 ops/sec)
Did 8957 ECDSA P-256 verify operations in 1078570us (8304.5 ops/sec)
The difference is in setting up the BN_MONT_CTX, either computing R^2 or n0.
I'm guessing R^2. The current algorithm needs to be constant-time, but we can
split out a variable-time one if necessary.

This includes a point validation, which figures into the overall cost of
an ECDH operation. If, say, point validation is slow because it uses
generic code, we'd like it to show up in benchmarks.
(Later I'd like to replace this mess with a simple byte-oriented ECDH
API. When that happens, I'll update the benchmark accordingly.)

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.

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

Thus this change moves some of the template code to base.h and puts it

There's a __pragma expression which allows this. Android builds us Windows with

MinGW doesn't understand MSVC's pragmas and warns a lot. #pragma warning is
safe to suppress, so wrap those to shush them. This also lets us do away with a
