This action instructs tar to pause until given signal is delivered.
The newer genfile tool uses this action for communication between
genfile and tar in exec mode. This eliminates race conitions and
speeds up the tests based on exec mode.

Changes to src/create.c and src/incremen.c are partially
based on patch from Alexander Peslyak <solar at openwall.com>.
The new testcases require paxutils commit f653a2b or later.
* src/common.h (struct name): New member `cmdline'.
(dump_file): Change type of the 2nd argument to bool.
(file_removed_diag, dir_removed_diag): New prototypes.
(addname): New argument `cmdline'.
(name_from_list): Change return value.
* src/create.c (dump_dir0, dump_dir): top_level is bool.
(create_archive): Update calls to name_from_list.
Take advantage of the name->cmdline to set top_level argument
during incremental backups.
(dump_file0): top_level is bool.
Do not bail out if a no-top-level file disappears during incremental
backup, use file_removed_diag instead.
(dump_filed): top_level is bool.
* src/incremen.c (update_parent_directory): Silently ignore
ENOENT. It should have already been reported elsewhere.
(scan_directory): Use dir_removed_diag to report missing directories.
* src/misc.c (file_removed_diag, dir_removed_diag): New functions.
* src/names.c (name_gather): Set ->cmdname.
(addname): Likewise. All uses updated.
(name_from_list): Return struct name const *. All uses updated.
* tests/filerem01.at: New testcase.
* tests/filerem02.at: New testcase.
* tests/Makefile.am, tests/testsuite.at: Add filerem01.at, filerem02.at
* tests/grow.at, test/truncate.at: Use new syntax for genfile --run.
* NEWS: Update.
* doc/tar.texi: Minor fix.
