Implement stricter scalar malleability checking for signatures.
...
Previously, we were checking that the highest 3 bits were unset, which still
leaves 2^253 - 2^252 + 27742317777372353535851937790883648493 potential scalars
for the `s` component of a signature which are not strictly mod \ell.
This change fixes that.
Note: This change makes ed25519-dalek incompatible with ed25519-donna in that
some signatures produced by donna will be verifiable by donna but NOT VERIFIABLE
by dalek. On the other hand, libsodium exports a -DED25519_COMPAT feature,
which when enabled, means it is compatible with dalek with the
`legacy_compatibility` feature disabled. Otherwise, libsodium's behaviour is
identical to the behaviour enabled by default in this patch.

* ADD new "batch" feature for feature-gating ed25519 batch verification; off by
default. The "batch" feature is the only thing which depends on all of the
`rand` crate, since it requires the functionality of `rand::thread_rng()`.
Without batch verification, the rest of ed25519-dalek only depends on
`rand_os` and `rand_core`.

This implements https://github.com/dalek-cryptography/ed25519-dalek/issues/64
You can still choose the "prehash" algorithm, as long as it has 64 bytes of
output. Otherwise, everything is hardcoded to use sha2::Sha512. To use a
different implementation you'll need a [patch.crates-io] section in cargo
config.

Move PublicKey point decompression into initialisation.
...
This caches the public key internally so that we effectively get a free
speedup on key reuse in regular signature verification, similar to that in
batch verification. (However, this also "speeds up"¹ batch verifications.)
¹ Less of a speed up than moving the computation elsewhere, but the speed up
on reuse still also applies to key reuse for batch verification.
