4c0077a07d Fix RemoteStore::addToStore() latency 
Since 6185d25e52, this was very
latency-bound since it required a round-trip for every 32 KiB. So for
example copying a 514 MiB closure over a virtual ethernet device with
a articial delay of just 1 ms took 343s. Now it takes 2.7s.

Fixes #3372.

2274f63453 Get rid of basicDerivation::findOutput 
It's a tiny function which is:

 - hardly worth abstrating over, and also only used once.

 - doesn't work once we get CA drvs

I rewrote the one callsite to be forwards compatable with CA
derivations, and also potentially more performant: instead of reading in
the derivation it can ust consult the SQLite DB in the common case.

bc109648c4 Get rid of LocalStore::addToStoreCommon 
I got it to just become `LocalStore::addToStoreFromDump`, cleanly taking

`LocalStore::addToStore(...Path...)` is now just a simple wrapper with a
bare-bones sinkToSource of the right dump command.

This reverts commit a2c27022e9. See
addToStoreSlow(), we don't need to handle this case efficiently
anymore. In fact, we can almost remove the method/hashAlgo arguments
since the non-recursive and/or non-SHA256 are almost not used anymore.

8173e7bfef Fix localhost::addToStore(...Path...) 
We were calculating the nar hash wrong when the file ingestion method
was flat. I don't think there's anything we can do in that case but dump
the file again, so that's what I do.

As an optomization, we again could reuse the original dump for just the
recursive and non-sha256 case, but I rather do that after this fix, and
after my other PRs which deduplicate this code.

it there.

230c9b4329 Change types to prepare the way for CA derivations 
We've added the variant to `DerivationOutput` to support them, but made
`DerivationOutput::path` partial to avoid actually implementing them.

With this chage, we can all collaborate on "just" removing
`DerivationOutput::path` calls to implement CA derivations.

fedfc913ad Use more std::visit to prepare for new variant 
N.B. not using `std::visit` for fetchurl because there is no attempt to
handle all the cases (e.g. no `else`) and lambda complicates early
return.

8e0d0689be Only store hash of fixed derivation output 
we don’t need a full storepath for a fixedoutput derivation. So just
putting the ingestion method + the hash is sufficient.

34f25124ba Make LocalStore::addToStore(srcPath) run in constant memory 
This reduces memory consumption of

  nix-instantiate \
    -E 'with import <nixpkgs> {}; runCommand "foo" { src = ./blender; } "echo foo"' \
    --option nar-buffer-size 10000

(where ./blender is a 1.1 GiB tree) from 1716 to 36 MiB, while still
ensuring that we don't do any write I/O for small source paths (up to
'nar-buffer-size' bytes). The downside is that large paths are now
always written to a temporary location in the store, even if they
produce an already valid store path. Thus, adding large paths might be
slower and run out of disk space. ¯\_(ツ)_/¯ Of course, you can always
restore the old behaviour by setting 'nar-buffer-size' to a very high
value.

af95a7c16b Add name to BasicDerivation 
We always have a name for BasicDerivation, since we have a derivation
store path that has a name.
