Fix #9859

It's a breaking change but that's fine; we can just update Hydra to use
the new bindings.

2d74b56aee fix location of _redirects file 
the Netlify `_redirects` file must be in the root directory [0] of the
files to serve, and mdBook copies all the files in `src` that aren't
`.md` to the output directory [1].

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

Print error messages but not traces 
This makes output of values that include errors much cleaner.

Before:
```
nix-repl> { err = builtins.throw "uh oh!"; }
{ err = «error:
       … while calling the 'throw' builtin
         at «string»:1:9:
            1| { err = builtins.throw "uh oh!"; }
             |         ^

       error: uh oh!»; }
```

After:
```
nix-repl> { err = builtins.throw "uh oh!"; }
{ err = «error: uh oh!»; }
```

But if the whole expression throws an error, source locations and (if
applicable) a stack trace are printed, like you'd expect:

```
nix-repl> builtins.throw "uh oh!"
error:
       … while calling the 'throw' builtin
         at «string»:1:1:
            1| builtins.throw "uh oh!"
             | ^

       error: uh oh!
```

Catch Error, not BaseError in ValuePrinter 
`BaseError` includes `Interrupt`. We probably don't want the value
printer to tell you you pressed Ctrl-C while it was working.

Rename yellowtxt -> magentatxt 
`yellowtxt` wraps its value with `ANSI_WARNING`, but `ANSI_WARNING` has
been equal to `ANSI_MAGENTA` for a long time. Now the name is updated.

ec5cc1026d absPath: Explicitly check if path is empty before accessing it 
It is entirely possible for the path to be an empty string and many
unit tests actually pass it as an empty string (e.g. both_roundrip or
turnsEmptyPathIntoCWD). In this case, without this patch, absPath will
perform a one-byte out-of-bounds access.

This was discovered while enabling the nix test suite on Alpine where
we compile all software with `-D_GLIBCXX_ASSERTIONS=1`, thus resulting
in a test failure on Alpine.

libexpr: Support structured error classes 
While preparing PRs like #9753, I've had to change error messages in
dozens of code paths. It would be nice if instead of

    EvalError("expected 'boolean' but found '%1%'", showType(v))

we could write

    TypeError(v, "boolean")

or similar. Then, changing the error message could be a mechanical
refactor with the compiler pointing out places the constructor needs to
be changed, rather than the error-prone process of grepping through the
codebase. Structured errors would also help prevent the "same" error
from having multiple slightly different messages, and could be a first
step towards error codes / an error index.

This PR reworks the exception infrastructure in `libexpr` to
support exception types with different constructor signatures than
`BaseError`. Actually refactoring the exceptions to use structured data
will come in a future PR (this one is big enough already, as it has to
touch every exception in `libexpr`).

The core design is in `eval-error.hh`. Generally, errors like this:

    state.error("'%s' is not a string", getAttrPathStr())
      .debugThrow<TypeError>()

are transformed like this:

    state.error<TypeError>("'%s' is not a string", getAttrPathStr())
      .debugThrow()

The type annotation has moved from `ErrorBuilder::debugThrow` to
`EvalState::error`.
