offload: '{send,receive}-files' wait for completion of the transfer.
Fixes situations where the remote 'guix build' is invoked before the
.drv has been completely copied, as reported at
<https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00174.html>.
In some cases 'send-files' would return before the other end is done
importing the files, and so the subsequent 'guix build' invocation would
just miss the .drv file it refers to.

call.

files in binary mode, with no buffering.

* guix/build/union.scm: Rewrite; only 'file=?' remains unchanged. Remove
'tree-union' and 'delete-duplicate-leaves' exports. Merge inputs in a
breadth-first fashion. Follow symlinks for purposes of making decisions
about the merge.

parameter to #:version. Add #:public-key parameter. Call

'example.gnu.org'.
("not a number", "wrong version number", "valid
narinfo-signature->canonical-sexp"): Use 'signature-field' instead of
'signature' or %SIGNATURE.
(test-error-condition): Add 'message-rx' parameter and honor it.
("corrupt signature data", "unauthorized public key", "invalid
signature"): Adjust accordingly.
(narinfo, %signed-narinfo): Remove.
