list-runtime-roots: Canonicalize store items.
Looking at 'addAdditionalRoots' in libstore/gc.cc, it looks like it
should always have been this way.  In practice it probably doesn't make
much of a difference.

* nix/scripts/list-runtime-roots.in (canonicalize-store-item): New
procedure.
<top level>: Use it.

list-runtime-roots: Do not use 'lsof'.
This makes things a bit faster (0.8s instead of 1.4s on my laptop).

* nix/scripts/list-runtime-roots.in (lsof-roots): Remove.
(proc-fd-roots): Return the empty list when 'scandir' returns #f.
(referenced-files): New procedure.
Use it at the top level.

Ludovic Courtès 94d92c7796
daemon: Add "builtin:download" derivation builder.
This ensures that 1) the derivation doesn't change when Guix changes;
2) the derivation closure doesn't contain Guix and its dependencies; 3)
we don't have to rely on ugly chroot hacks.

Adapted from Nix commit 0a2bee307b20411f5b0dda0c662b1f9bb9e0e131.

* nix/libstore/build.cc (DerivationGoal::runChild): Add special case for
'isBuiltin(drv)'.  Disable chroot when 'isBuiltin(drv)'.
* nix/libstore/builtins.cc, nix/libstore/builtins.hh,
nix/scripts/download.in, guix/scripts/perform-download.scm: New files.
* guix/ui.scm (show-guix-help)[internal?]: Add 'perform-download'.
* nix/local.mk (libstore_a_SOURCES): Add builtins.cc.
(libstore_headers): Add builtins.hh.
(nodist_pkglibexec_SCRIPTS): Add 'scripts/download'.
* config-daemon.ac: Emit 'scripts/download'.
* Makefile.am (MODULES): Add 'guix/scripts/perform-download.scm'.
* tests/derivations.scm ("unknown built-in builder")
("'download' built-in builder")
("'download' built-in builder, invalid hash")
("'download' built-in builder, not found")
("'download' built-in builder, not fixed-output"): New tests.
