Reduce memory consuption when handling the -T option.
The commit cdb27293 made the -T option more flexible, but
incurred a very considerable memory overhead by storing
all file names in the argument array. In case of very
big file lists this caused tar to run out of memory. This
was reported by Christian Wetzel <[email protected]>
on March 14, 2013
(http://lists.gnu.org/archive/html/bug-tar/2013-03/msg00018.html).
On the other hand, Michal Žeidl discovered that tar misfunctioned
when given empty file lists or lists with the trailing newline
misssing in the last entry. This was reported by Pavel Raiskup
on July 23
(http://lists.gnu.org/archive/html/bug-tar/2013-07/msg00009.html
and
msg00010.html).

Fix some problems with negative and out-of-range integers.
Original problem reported for HP-UX LVM v2.2 by Michael White in
<http://lists.gnu.org/archive/html/bug-tar/2012-10/msg00000.html>.
This patch fixes some other gotchas that I noticed.
* gnulib.modules: Add extern-inline.
* src/common.h: Use _GL_INLINE_HEADER_BEGIN,
_GL_INLINE_HEADER_END.
(COMMON_INLINE, max, min): New macros.
(represent_uintmax, valid_timespec): New inline functions.
(SYSINT_BUFSIZE): New constant.
(sysinttostr, strtosysint, decode_timespec): New decls.
* src/create.c (start_private_header): Silently bring the time_t
value into range; it is now the caller's responsibility to deal
with any overflow error. Use uid 0 and gid 0 rather than the
user's uid/gid, since the faked header isn't "owned" by the user
and the uid/gid could in theory be out of range. Leave major and
minor zeroed.
(FILL): Remove.
(write_gnu_long_link): Let start_private_header zero things out.
* src/create.c (write_gnu_long_link, write_extended):
* src/xheader.c (xheader_write_global):
Use start_time, not current time; no point hammering on the clock.
* src/compare.c (diff_multivol): Check that offset, size are
in range.
* src/incremen.c (read_incr_db_01, write_directory_file_entry):
Allow negative time_t, dev_t, and ino_t.
* src/list.c (max): Remove (moved to common.h).
(read_header): Check that size is in range.
(from_header): Return intmax_t, not uintmax_t, to allow negative.
All callers changed. At compile time, check assumptions about
intmax_t and uintmax_t. Use bool for booleans. Avoid overflow
hassles on picky hosts.
(mode_from_header): Last arg is now bool *, not unsigned *.
All callers changed.
(simple_print_header): Do not assume UID, GID fit in 'long'.
* src/list.c (from_header):
* src/xheader.c (out_of_range_header):
Arg is now a plain minimum value, not minus minval converted to
uintmax_t. All callers changed.
* src/misc.c (COMMON_INLINE): New macro.
(sysinttostr, strtosysint, decode_timespec): New functions.
* src/sparse.c (oldgnu_add_sparse, oldgnu_fixup_header)
(star_fixup_header):
Check for offset overflow.
(decode_num): Clear errno before calling strtoumax.
* src/tar.c (expand_pax_option): Don't discard nanoseconds.
* src/xheader.c (assign_time_option): Allow negative time_t.
(decode_record): Simplify, since out-of-range string is guaranteed
to produce a value exceeding len_max.
(xheader_read): Last arg is off_t, not size_t.
Caller should diagnose negative arg, as needed.
Check that it's in range.
(enum decode_time_status): Remove.
(_decode_time): Remove, folding into decode_time.
(decode_time): Return bool, not enum decode_time_status.
Rely on decode_timespec to do most of the work.
(code_signed_num): New function.
(code_num): Use it.
(decode_signed_num): New function.
(decode_num): Use it.
(gid_coder, gid_decoder, uid_coder, uid_decoder,
sparse_map_decoder)
(sparse_map_decoder): Code and decode negative values.

Fix creation of incremental archives when a subdirectory becomes
a mountpoint.
When used with --listed-incrfental and --one-file-system, tar
was unable to cope with directories that had once been part of the
dumped system and became separate mount points afterwards.
The bug
has been reported and a fix proposed by Nathan Stratton Treadway.
* src/incremen.c (procdir): If one_file_system_option is in
effect,
clear out dumpdir info from the directory.
* tests/Makefile.am: Add new testcase.
* tests/listed05.at: New testcase.
* tests/testsuite.at (AT_PRIVILEGED_PREREQ): New macro.
include listed05.at.
* THANKS: Update.
