The race is unlikely, as timeout(1) needs to receive a signal
in the few operations between waitpid() returning and exit().
Also the system needs to have reallocated the just released pid
in this time window.
Previously we never disabled the signal handler that sent
the termination signal to the "child" pid. However once waitpid()
has reaped the child, the system is free to allocate that pid,
so we must ensure we don't process any further signals.
* build-aux/gen-lists-of-programs.sh: Build timeout(1) optionally...
* configure.ac: ...predicated on sigsuspend() being available.
* src/timeout.c (block_cleanup): A new function to ensure the
cleanup() handler is disabled after waitpid has returned.
(main): Use sigsuspend() to wait with cleanup() enabled but
disabled once it returns, and thus disabled for the waitpid() call.
(monitored_pid): Change to the more accurate pid_t.
* NEWS: Mention the fix.

* src/tail.c (check_fspec): Only enable printing of the file header
if we've actually read some data and this is a new file. Also
move printing of the file header to...
(dump_remainder): ...here, to allow printing only when data read.
* tests/tail-2/overlay-headers.sh: A new test for suspension
and resumption of tail.
* tests/local.mk: Reference the new test.

* src/copy.c (punch_hole): Work around an empty definition

st_size unless we've previously used seek() to determine

case st_size was 64KiB while ST_BLKSIZE() was 4KiB.

Installing with -j2 or greater could result in a failure like
/bin/sh: line 29: /P/bin/install: Permission denied
when /P/bin/install specifies your PATH-selected install program.
This would arise because we're using "install" to install all
man/*.1 files, and that command would run concurrently with the one
that installs "/P/bin/install" itself. We would run this command:
"src/ginstall src/ginstall /P/bin/install", and it would result
in intervals during which the destination file does not exist,
is empty or incomplete and not executable. We addressed this
problem long ago for installation of actual binaries by telling the
installation rules to use our just-built bin/ginstall (only when not
cross-compiling) rather than the PATH-resolved "install" program.
This change is to do the same for those .1 files.
* src/local.mk (INSTALL): Override automake's default of something
like "INSTALL = /P/bin/install -c".
(INSTALL_PROGRAM): Now that we set INSTALL, there is no longer any
need to set this derived variable. Its default definition,
"INSTALL_PROGRAM = ${INSTALL}" does what we require.
