Rebecca Turner ee423f391d Rewrite REPL test parser
- Use a recursive descent parser so that it's easy to extend.
- Add `@args` to enable customizing command-line arguments
- Add `@should-start` to enable `nix repl` tests that error before
  entering the REPL
- Make sure to read all stdout output before comparing. This catches
  some extra output we were tossing out before!

Rebecca Turner 2a98ba8b97 Add pre-commit checks
The big ones here are `trim-trailing-whitespace` and `end-of-file-fixer`
(which makes sure that every file ends with exactly one newline
character).

eldritch horrors afb839a0c9 libexpr: associate let exprs with the correct StaticEnv
static env association is from expr to its enclosing scope, but let
exprs set their association to their *inner* scope. this skips one level
of envs and will cause segfaults if the parent is a with expr.

fixes #145

eldritch horrors b3599166ad libexpr: sort binding name in debugger
not doing this exposes the binding name order to the annoying
interference of parse order on symbol order, which wouldn't be so bad if
it didn't make the tests less reliable and, importantly, dependent on
linker behavior (due to primop initialization being done in static
initializer, and the order of static initializers being defined only
within a single translation unit).

fixes #143

jade 78513b1fc8 repl_characterization: eat newlines after commands and source-dir paths
This is because they are unrepresentable in the source files with
commentary but not in the output, so we should just eat them in
normalization. It's ok.

jade 18ed6c3bdf Implement a repl characterization test system
This allows for automating using the repl without needing a PTY, with
very easy to write test files.

jade 38571c50e6 Implement a parser for a literate testing system for the repl
This parser can be reused for other purposes. It's inspired by
https://bitheap.org/cram/

Although eelco's impostor exists https://github.com/mobusoperandi/eelco,
it is not very nice to depend on out of tree testing frameworks with no
way to customize them.
