Reform positional argument parsing (#523)
This diff makes positional argument parsing much cleaner, along with
adding a bunch of tests. Just's positional argument parsing is rather,
complex, so hopefully this reform allows it to both be correct and stay
correct.

User-visible changes:

- `just ..` is now accepted, with the same effect as `just ../`

- `just .` is also accepted, with the same effect as `just`

- It is now an error to pass arguments or overrides to subcommands
  that do not accept them, namely `--dump`, `--edit`, `--list`,
  `--show`, and `--summary`. It is also an error to pass arguments to
  `--evaluate`, although `--evaluate` does of course still accept
  overrides.

  (This is a breaking change, but hopefully worth it, as it will allow us
  to add arguments to subcommands which did not previously take
  them, if we so desire.)

- Subcommands which do not accept arguments may now accept a
  single search-directory argument, so `just --list ../` and
  `just --dump foo/` are now accepted, with the former starting the
  search for the justfile to list in the parent directory, and the latter
  starting the search for the justfile to dump in `foo`.

Reform Parser (#509)
Just's first parser performed both parsing, i.e the transformation of a
token stream according to the language grammar, and a number of consistency
checks and analysis passes.

This made parsing and analysis quite complex, so this diff introduces a
new, much cleaner `Parser`, and moves existing analysis into a dedicated
`Analyzer`.

Refactor lexer tests (#498)
- Refactor the lexer tests to be more readable, abandoning the
  previous string-based summary DSL in favor of a more obvious
  sequence of `TokenKinds` with optional lexemes. The new tests
  also test that token lexemes are correct.

- Move duplicated `unindent` function into a shared crate,
  `test-utilities`. This new versionless dev-dependency will
  prevent publishing to crates.io, at least until rust-lang/cargo/pull/7333
  makes it into stable. If we publish a new version before then,
  test-utilities will need to be published to crates.io, so we can depend
  on it by version.

Use pub(crate) instead of pub (#471)
Eventually, there will probably be a `crate` visibility specifier that
does the same thing as `pub(crate)`. This commit replaces `pub` with
`pub(crate)`, so when `crate` is available we can easily switch to it.

Add env_var(key) and env_var_or_default(key, default) functions (#280)
`env_var(key)` looks up the value of the environment variable with name `key`, aborting execution if it is not found.

`env_var_or_default(key, default)` looks up the value of the environment variable with name `key`, returning `default` if it is not found.
