Replace $NIX_REMOTE_SYSTEMS with an option "builder-files"
Also, to unify with hydra-queue-runner, allow it to be a list of
files.

build-remote: Fix fallback to other machines when connecting fails
Opening an SSHStore or LegacySSHStore does not actually establish a
connection, so the try/catch block here did nothing. Added a
Store::connect() method to test whether a connection can be
established.

Add an option for specifying remote builders
This is useful for one-off situations where you want to specify a
builder on the command line instead of having to mess with
nix.machines. E.g.

  $ nix-build -A hello --argstr system x86_64-darwin \
    --option builders 'root@macstadium1 x86_64-darwin'

will perform the specified build on "macstadium1".

It also removes the need for a separate nix.machines file since you
can specify builders in nix.conf directly. (In fact nix.machines is
yet another hack that predates the general nix.conf configuration
file, IIRC.)

Note: this option is supported by the daemon for trusted users. The
fact that this allows trusted users to specify paths to SSH keys to
which they don't normally have access is maybe a bit too much trust...

build-remote: Ugly hackery to get build logs to work
The build hook mechanism expects build log output to go to file
descriptor 4, so do that.

Support arbitrary store URIs in nix.machines
For backwards compatibility, if the URI is just a hostname, ssh://
(i.e. LegacySSHStore) is prepended automatically.

Also, all fields except the URI are now optional. For example, this is
a valid nix.machines file:

  local?root=/tmp/nix

This is useful for testing the remote build machinery since you don't
have to mess around with ssh.

Remove $NIX_BUILD_HOOK and $NIX_CURRENT_LOAD
This is to simplify remote build configuration. These environment
variables predate nix.conf.

The build hook now has a sensible default (namely build-remote).

The current load is kept in the Nix state directory now.

build-remote: Don't copy the .drv closure
Since build-remote uses buildDerivation() now, we don't need to copy
the .drv file anymore. This greatly reduces the set of input paths
copied to the remote side (e.g. from 392 to 51 store paths for GNU
hello on x86_64-darwin).

Add a dummy Store::buildPaths() method
This default implementation of buildPaths() does nothing if all
requested paths are already valid, and throws an "unsupported
operation" error otherwise. This fixes a regression introduced by
c30330df6f in binary cache and legacy
SSH stores.

Guillaume Maudoux a143014d73 lexer: remove catch-all rules hiding real errors
With catch-all rules, we hide potential errors.
It turns out that a4744254 made one cath-all useless. Flex detected that
is was impossible to reach.
The other is more subtle, as it can only trigger on unfinished escapes
in unfinished strings, which only occurs at EOF.

Fix hash computation when importing NARs greater than 4 GiB
This caused "nix-store --import" to compute an incorrect hash on NARs
that don't fit in an unsigned int. The import would succeed, but
"nix-store --verify-path" or subsequent exports would detect an
incorrect hash.

A deeper issue is that the export/import format does not contain a
hash, so we can't detect such issues early.

Also, I learned that -Wall does not warn about this.

StorePathCommands: Build installables
So for instance "nix copy --to ... nixpkgs.hello" will build
nixpkgs.hello first. It's debatable whether this is a good idea. It
seems desirable for commands like "nix copy" but maybe not for
commands like "nix path-info".

Eelco Dolstra d48c973ece
Set default installable
Thus

  $ nix build -f foo.nix

will build foo.nix.

And

  $ nix build

will build default.nix. However, this may not be a good idea because
it's kind of inconsistent, given that "nix build foo" will build the
"foo" attribute from the default installation source (i.e. the
synthesis of $NIX_PATH), rather than ./default.nix. So I may revert
this.

Interpret any installable containing a slash as a path

Eelco Dolstra 7ee81f3887
Make StorePathsCommand a subclass of InstallablesCommand
This allows commands like 'nix path-info', 'nix copy', 'nix verify'
etc. to work on arbitrary installables. E.g. to copy geeqie to a
binary cache:

  $ nix copy -r --to file:///tmp/binary-cache nixpkgs.geeqie

Or to get the closure size of thunderbird:

  $ nix path-info -S nixpkgs.thunderbird
