Frank Denis 728b26c2c1 Remove edwards25519sha512batch
Tagged as deprecated for years, never imported by `<sodium.h>`, and
intentionally never documented.

`edwards25519sha512batch` was just around for ABI compatibility
with NaCl, but no projects seem to be using it.

Loup VaillantandFrank Denis e7e378fad1 Secretbox: explained non-portable behavior (#936)
Addresses #934

Some tools believe that comparing pointers, *even after converting them
to integers*, is undefined. A comment acknowledging this (as well as the
necessity of the comparison to begin with), can facilitate audits.

Frank Denis ef89aea64e Merge pull request #884 from isislovecruft/feature/scalar-succeed-fast
Optimisation to succeed fast when checking signature scalar is reduced.

Isis Lovecruft 6136871607 Optimisation to succeed fast when checking signature scalar is reduced.
This provides a minor optimisation for ed25519 signature verification, when used
without the -DED25519_COMPAT feature, to strictly check for a fully reduced
scalar, `s`, component in variable time by first checking that the most
significant *four* bits are unset, and only if any of them are set proceed to
the `sc25519_is_canonical` check which performs the full reduction.  This should
result in succeeding fast for the check on roughly half of all well-formed,
canonicalised signatures.

This is safely backwards compatible with the previous implementation
of strict checking for signature scalars.
