* guix/scripts/offload.scm (offload): Remove default value for
'build-timeout'. Pass '--timeout' to the remote 'guix build'
process.
(transfer-and-offload, process-request): Remove default value for
'build-timeout'.
* guix/scripts/offload.scm (transfer-and-offload): New procedure, with
core formerly in 'process-request'.
(choose-build-machine): Remove 'requirements' parameter.
(process-request): Reply 'decline' when none of MACHINES matches the
requirements, and 'postpone' when MACHINES are busy.
* guix/scripts/offload.scm (machine-choice-lock-file,
machine-slot-file, acquire-build-slot, release-build-slot): New
procedures.
(choose-build-machine): Operate with (machine-choice-lock-file)
taken. Acquire a build slot for each of MACHINES. Release those not
used.
* guix/scripts/offload.scm (lock-machine, unlock-machine): Remove.
(lock-file, unlock-file): New procedures.
(with-file-lock): New macro.
(with-machine-lock): Rewrite in terms of 'with-file-lock'.
* doc/guix.texi (Invoking guix package): Explain where packages are
searched for and link to "Package Modules".
(Defining Packages) <example>: Use 'define-module' clause instead of
'use-modules'. Explain why and link to "Package Modules".
(Invoking guix build): Explain where packages aer searched for and
link to "Package Modules".
(Package Modules): Explain that (gnu packages ...) is scanned.
* gnu/packages/patches/coreutils-skip-nohup.patch: patch taken from the git
repository of coreutils, that makes sure tests/misc/nohup.sh does not fail
when /dev/tty does not exist.

unlock-machine): New procedures.
(with-machine-lock): New macro.
(process-request): Wrap 'send-files' and 'retrieve-files' calls in
'with-machine-lock'.
* tests/utils.scm (temp-file): New variable.
("fcntl-flock"): Rewrite to actually test whether the child process
waits for the lock to be released. The previous test was wrong
because (1) it expected F_SETLK semantics, not F_SETLKW, and (2) it
got EBADF because of a mismatch between the open mode and the lock
style.
* doc/guix.texi (Invoking guix package): Remove documentation for
--dry-run, --fallback, --no-substitutes, and --max-silent-time. Add a
cross-ref to "Invoking guix build".
