390269ed87 Simplify the handling of the hash modulo 
Rather than having four different but very similar types of hashes, make
only one, with a tag indicating whether it corresponds to a regular of
deferred derivation.

This implies a slight logical change: The original Nix+multiple-outputs
model assumed only one hash-modulo per derivation. Adding
multiple-outputs CA derivations changed this as these have one
hash-modulo per output. This change is now treating each derivation as
having one hash modulo per output.
This obviously means that we internally loose the guaranty that
all the outputs of input-addressed derivations have the same hash
modulo. But it turns out that it doesn’t matter because there’s nothing
in the code taking advantage of that fact (and it probably shouldn’t
anyways).

The upside is that it is now much easier to work with these hashes, and
we can get rid of a lot of useless `std::visit{ overloaded`.

057f9ee190 nix profile install: Don't use queryDerivationOutputMap() 
Instead get the outputs from Installable::build(). This will also
allow 'nix profile install' to support impure derivations.

Fixes #6286.

cbcb69a39c nix: allow whitespace characters before command in repl 
Before this change, processLine always uses the first character
as the start of the line. This cause whitespaces to matter at the
beginning of the line whereas it does not matter anywhere else.

This commit trims leading white spaces of the string line so that
subsequent operations can be performed on the string without explicitly
tracking starting and ending indices of the string.

540d7e33d8 Retry substitution after an incomplete closure only once 
This avoids an infinite loop in the final test in

by accident (because we were clearing wantedOutputs in between).

This reverts commit 50a35860ee.

With this change Nix fails to open bzip2 logfiles that were created from
builds with no stdout/stderr.

f18607549c Fix makeContentAddressed() on self-references 
LocalStore::addToStore() since
79ae9e4558 expects a regular NAR hash,
rather than a NAR hash modulo self-references. Fixes #6300.

Also, makeContentAddressed() now rewrites the entire closure (so 'nix
store make-content-addressable' no longer needs '-r'). See #6301.

This allows closures to be imported at evaluation time, without
requiring the user to configure substituters. E.g.

  builtins.fetchClosure {

    from = "https://cache.ngi0.nixos.org";
