fa8515d7ec Set regex_constants::match_continuous for quicker search 
match_continuous limits the search to the current start position,
instead of searching the entire file.

On libc++, this improves performance dramatically:

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.

Restore backwards-compat for current builtins.fetchGit 
If a repo is dirty, it used to return a `rev` object with an "empty"
sha1 (0000000000000000000000000000000000000000). Please note that this
only applies for `builtins.fetchGit` and *not* for `builtins.fetchTree{
type = "git"; }`.

Merge legacy fetchGit-builtin with the generic fetchTree-function 
The original idea was to implement a git-fetcher in Nix's core that
supports content hashes[1]. In #3549[2] it has been suggested to
actually use `fetchTree` for this since it's a fairly generic wrapper
over the new fetcher-API[3] and already supports content-hashes.

This patch implements a new git-fetcher based on `fetchTree` by
incorporating the following changes:

* Removed the original `fetchGit`-implementation and replaced it with an
  alias on the `fetchTree` implementation.

* Ensured that the `git`-fetcher from `libfetchers` always computes a
  content-hash and returns an "empty" revision on dirty trees (the
  latter one is needed to retain backwards-compatibility).

* The hash-mismatch error in the fetcher-API exits with code 102 as it
  usually happens whenever a hash-mismatch is detected by Nix.

* Removed the `flakes`-feature-flag: I didn't see a reason why this API
  is so tightly coupled to the flakes-API and at least `fetchGit` should
  remain usable without any feature-flags.

* It's only possible to specify a `narHash` for a `git`-tree if either a
  `ref` or a `rev` is given[4].

* It's now possible to specify an URL without a protocol. If it's missing,
  `file://` is automatically added as it was the case in the original
  `fetchGit`-implementation.

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.

bc73590151 nix edit: call restoreSignals() before execvp-ing the $EDITOR 
Currently resizing of the terminal doesn't play nicely with
nix edit when using kakoune as the editor, as it relies on the
SIGWINCH signal which is trapped by nix. How this is not a problem
with e.g. vim is beyond me.

Virtually all other exec* calls are following a call to
restoreSignals(). This commit adds this behavior to nix edit
as well.

cff2157185 Revert "LocalStore::addToStore(srcPath): Handle the flat case" 
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.

592851fb67 LocalStore::addToStoreFromDump copy in chunks 
Rather than copying byte-by-byte, we let the coroutine know how much
data we would like it to send back to us.

9de96ef7d4 Dedup LocalStore::addToStore* 
The downsides is that the coroutine has byte-by-byte loop transfer. Will
fix that next.

c86fc3a965 Crudely make addToStoreFromDump take Source not string 
I just as little beyond the type as possible, so the implementation
changes this enables can be reviewed separately.
