print-dev-env: Avoid using unbound shellHook variable
Some tools which consume the "nix print-dev-env" rc script (such as
"nix-direnv") are sensitive to the use of unbound variables. They use
"set -u".

The "nix print-dev-env" rc script initially unsets "shellHook", then
loads variables from the derivation, and then evaluates "shellHook".
However, most derivations don't have a "shellHook" attribute.

So users get the error "shellHook: unbound variable". This can be
demonstrated with the command:

    nix print-dev-env nixpkgs#hello | bash -u

This commit changes the rc script to provide an empty fallback value
for the "shellHook" variable.

Closes: #7951 #8253

1ee42c5b88 builtin:fetchurl: Ensure a fixed-output derivation
Previously we didn't check that the derivation was fixed-output, so
you could use builtin:fetchurl to impurely fetch a file.

Color diff output in tests/functional/lang tests
Use `diff --color=always` to print colored output for language test
failures. I've also flipped the arguments so that expected lines missing
from the actual output will be marked with a red `-` and additional
lines found in the actual output will be marked with a green `+`.
Previously it was the other way around, which was very confusing.

Print the value in error: cannot coerce messages
This extends the `error: cannot coerce a TYPE to a string` message
to print the value that could not be coerced. This helps with debugging
by making it easier to track down where the value is being produced
from, especially in errors with deep or unhelpful stack traces.

202c5e2afc Start standardizing hash algo flags
Do this if we want to do `--hash-algo` everywhere, and not `--algo` for
hash commands.

The new `nix hash convert` is updated. Deprecated new CLI commands are
left as-is (`nix hash path` needs to be redone and is also left as-is).

03a6ca9b25 tests/functional/nix-profile.sh: Add missing --no-link
Otherwise we get a stray `tests/functional/result`, which can cause
spurious failures later.

(I got a failure because the test temp dir effecting the store dir
changed. This caused a test later because Nix didn't want to remove the
old `result` because it wasn't pointing inside the new Nix store.)

ce6d58a97c git fetcher: Add exportIgnore parameter
Enabled for fetchGit, which historically had this behavior,
among other behaviors we do not want in fetchGit.

fetchTree disables this parameter by default. It can choose the
simpler behavior, as it is still experimental.

I am not confident that the filtering implementation is future
proof. It should reuse a source filtering wrapper, which I believe
Eelco has already written, but not merged yet.

Restore ambiguous value printer for nix-instantiate
The Nix team has requested that this output format remain unchanged.

--eval` output will not parse correctly in many situations.

Unify and refactor value printing
Previously, there were two mostly-identical value printers -- one in
`libexpr/eval.cc` (which didn't force values) and one in
`libcmd/repl.cc` (which did force values and also printed ANSI color
codes).

This PR unifies both of these printers into `print.cc` and provides a
`PrintOptions` struct for controlling the output, which allows for
toggling whether values are forced, whether repeated values are tracked,
and whether ANSI color codes are displayed.

Additionally, `PrintOptions` allows tuning the maximum number of
attributes, list items, and bytes in a string that will be displayed;
this makes it ideal for contexts where printing too much output (e.g.
all of Nixpkgs) is distracting. (As requested by @roberth in
https://github.com/NixOS/nix/pull/9554#issuecomment-1845095735)

Please read the tests for example output.

Future work:
- It would be nice to provide this function as a builtin, perhaps
  `builtins.toStringDebug` -- a printing function that never fails would
  be useful when debugging Nix code.
- It would be nice to support customizing `PrintOptions` members on the
  command line, e.g. `--option to-string-max-attrs 1000`.

Fix segfault on infinite recursion in some cases
This fixes a segfault on infinite function call recursion (rather than
infinite thunk recursion) by tracking the function call depth in
`EvalState`.

Additionally, to avoid printing extremely long stack traces, stack
frames are now deduplicated, with a `(19997 duplicate traces omitted)`
message. This should only really be triggered in infinite recursion
scenarios.

Before:

    $ nix-instantiate --eval --expr '(x: x x) (x: x x)'
    Segmentation fault: 11

After:

    $ nix-instantiate --eval --expr '(x: x x) (x: x x)'

Build IFD in the build store when using eval-store.
Previously, IFDs would be built within the eval store, even though one
is typically using `--eval-store` precisely to *avoid* local builds.

Because the resulting Nix expression must be copied back to the eval
store in order to be imported, this requires the eval store to trust
the build store's signatures.
