Vicariously updates to `generic-array` 0.12, however this change also
removes `generic-array` as a direct dependency, as it can be sourced
from the `digest` crate.
This is too late for the 0.19.0 release (I missed it because I grepped for
"0.18.", and the version in the README doesn't specify a minor version), but it
will now be in line with the other version strings.
When we put out the 1.0.0-pre.0 release we can change both together (our docs
already say we've released it, because we inserted an extra version, oops).
As pointed out by @ruuda:

The earliest `byteorder` version without a `#[feature]` is `1.2.3`, so we
require any higher version than that one.

This partially re-adds functionality removed in commit

We would like to require ExactSizeIterator, but unfortunately we can't
do that, since ExactSizeIterators aren't chainable, for (in my opinion)
silly reasons (chaining two 4-billion-element ExactSizeIterators could
overflow on 32-bit systems). Instead we inspect the size hints manually
and assert that the lower and upper bounds are all equal.
This change provides a common convention for using allocator-dependent
features with:
#![cfg(feature = "alloc")]
When available, `Vec` is imported consistently as `prelude::Vec`, which
means modules that need access to `Vec` can simply do:
use prelude::*;
and if an allocator is available, `Vec` will be in the crate prelude.
This allows all `alloc` vs `std` gating to be handled in `lib.rs`,
`build.rs`, and `prelude.rs` so the rest of the codebase doesn't have to
do any gating whatsoever.
