treewide: refactor .attrs.sh detection
When specifying the `builder` attribute in `stdenv.mkDerivation`, this
will be effectively transformed into

    builtins.derivation {
      builder = stdenv.shell;
      args = [ "-e" builder ];
    }

This also means that `default-builder.sh` is never sourced and as a
result it's not guaranteed that `$NIX_ATTRS_SH_FILE` is set to a correct
location[1].

Also, we need to source `.attrs.sh` to source `$stdenv`. So, the
following is done now:

* If `$NIX_ATTRS_SH_FILE` points to a correct location, then use it.
  Directly using `.attrs.sh` is problematic for `nix-shell(1)` usage
  (see previous commit for more context), so prefer the environment
  variable if possible.

* Otherwise, if `.attrs.sh` exists, then use it. See [1] for when this
  can happen.

* If neither applies, it can be assumed that `__structuredAttrs` is
  turned off and thus nothing needs to be done.

[1] It's possible that it doesn't exist at all - in case of Nix 2.3 or
    it can point to a wrong location on older Nix versions with a bug in
    `__structuredAttrs`.

0b1edac8c0 nix-prefetch-bzr: match path name to fetchbzr name
fetchbzr always uses the derivation name `bzr-export`. nix-prefetch-bzr
should use the same name for its output. This avoids duplicate downloads
and problems with forbidden characters in bazaar repository names.

build-support: Fix nix-prefetch-* on OS X.
Fixes a regression on OS X introduced by f83af95.

Don't use --tmpdir for mktemp, because that flag doesn't exist on OS X.
However, using -t is deprecated in GNU coreutils, so as suggested by
@ip1981 we're now using parameter expansion on ${TMPDIR:-/tmp} to
provide /tmp as a fallback if TMPDIR is not set and use it instead.

Also use this approach for nix-prefetch-cvs now in order to stay
consistent.

build-support: Use mktemp -d in nix-prefetch-*.
Instead of relying on $$ to not collide with an existing path.

Quoting the Bash manual about $$:

> Expands to the process ID of the shell. In a () subshell, it expands
> to the process ID of the current shell, not the subshell.

So, this is different from $BASHPID:

> Expands to the process ID of the current bash process. This differs
> from $$ under certain circumstances, such as subshells that do not
> require bash to be re-initialized.

But even $BASHPID is prone to race conditions if the process IDs wrap
around, so to be on the safe side, we're using mktemp here.

Closes #3784.

e10001042d fetchbzr, fetchdarcs, fetchhg: use rev attr
This makes it match the behaviour of fetchgit and fetchsvn, so it's
easier to write scripts that support all of them.

063efadd69 nix-prefetch-{bzr,hg,svn}: print fetched revision 2014-06-11 14:42:39 +02:00

8c63762d64 - fetchbzr and nix-prefetch-bzr now only export, instead of cloning
- The option for cloning in nix-prefetch-bzr is removed
- ssl certificates are now ignored by fetchbzr

This means that no .bzr directory is downloaded.  Without this change, the
hash of the result is unpredictable, probably because of timestamping in the
.bzr directory.

Currently, the only package using fetchbzr is kicad.
