rhg: centralize parsing of `--rev` CLI arguments
This new module will be the place to implement more of the revset language
when we do so.

rust: Make NodePrefix allocation-free and Copy, remove NodePrefixRef
The `*Ref` struct only existed to avoid allocating `Vec`s
when cloning `NodePrefix`, but we can avoid having `Vec`
in the first place by using an inline array instead.
This makes `NodePrefix` 21 bytes (with 1 for the length)
which is smaller than before as `Vec` alone is 24 bytes.

churn: count lines that look like diff headers but are not
Previously, churn cannot count added lines that start with "++ " or removed
lines that start with "-- ".

rust: Exclude empty node prefixes
We presumably don’t want `--rev ""` to select every single revision,
even though the empty string is a prefix of all strings.

rust: Simplify error type for reading hex node IDs
If a string is not valid hexadecimal it’s not that useful to track the precise reason.

rust: replace Node::encode_hex with std::fmt::LowerHex
This avoids allocating intermediate strings.

rhg: Build in release mode on CI
This follows
e73b40c790ec which made tests use the release executable.
With
e73b40c790ec but not this, tests are skipped on CI
because the executable is missing.
