* src/common.h (namebuf_t): New typedef.
(namebuf_create, namebuf_free)

(remname): New prototype.
* src/misc.c (struct namebuf): New structure.
(namebuf_create, namebuf_free)
(namebuf_name): New functions.
* src/create.c (dup_dir0): Remove is_avoided_name
checks. This is taken care of in update_archive.
* src/incremen.c (scan_directory): Use namebuf
to produce full file names.
* src/names.c (nametail): Remove extra level of
indirection. All uses updated.
(avoided_name_table, add_avoided_name)
(is_avoided_name): Remove.
* src/update.c (update_archive): Change algorithm.
Instead of adding unmodified files to the avoided_name
table, create namelist so that it contains only
modified files.
* tests/Makefile.am: Add update01.at, update02.at
* tests/testsuite.at: Likewise.
* tests/update.at (AT_KEYWORDS): Add update00.

timespec_cmp using the timespec precision provided by the
current archive format.
* src/common.h (tar_timespec_cmp): New declaration.
* src/compare.c (diff_file): Use tar_timespec_cmp.
* src/extract.c (file_newer_p): Likewise.
* src/update.c (update_archive): Likewise.
* tests/truncate.at: Reverted changes
* tests/update.at: Reverted changes
1-second boundaries. This prevents tests from failing on hosts
like Solaris 8 that have nanosecond-resolution file time stamps.
* tests/update.at: Likewise.
