Pavel Raiskup 1e8b786e65 Fix non-deterministic archive type detection
Due to analysis of partly uninitialized read-ahead buffer
(short_read call), we sometimes mistakenly classified very small
compressed archives as non-compressed; which in turn caused
extraction failure.

* src/buffer.c (check_compressed_archive): Don't assume that
archives smaller than BLOCKSIZE could be non-compressed, as tar
header always has at least one block.

Sergey Poznyakoff 795877532e Fix a bug in multi-volume archive creation.
When creating multivolume archives, the bufmap code in buffer.c
implicitly assumed that the members are stored in the archive
contiguously, ignoring the member (and eventual extended) headers
between them.  This worked until the member header happened to be
at the very beginning of the volume, in which case its length was
included in the calculation of the stored size and size left to
store.  Due to this, the GNUFileParts extended header contained
invalid GNU.volume.offset value, and the resulting archive failed
to extract properly.

This patch also eliminates improper listing of file part headers
as regular files, when creating multivolume posix archives with -v.

* src/buffer.c (bufmap): New member nblocks.  Counts number of blocks
of file data written since reset.
(bufmap_reset): Reset nblocks to 0.
(_flush_write): Update nblocks.  When computing offset difference for
bufmap_reset, count only data blocks, not headers.
(close_archive): Flush archive until all blocks are written.
(add_chunk_header): Use simple_finish_header instead of finish_header
to avoid listing chunk header as regular file in verbose mode.
* tests/multiv10.at: New test case.
* tests/Makefile.am: Add new test.
* tests/testsuite.at: Add new test.

Pavel Raiskup 00f928642f sparse: fix pax extraction for unicode filenames
Make sure that 'GNU.sparse.name' header has higher priority than
(for sparse-purposes artificially modified) 'path' pax header.

Historically, the 'GNU.sparse.name' header comes before 'path';
this caused that modified 'path' header won and that is not what
we want in sparse "capable" tar implementation.

code from path_decoder.

Jeremy Bobbio 13d04fe6ae New option --clamp-mtime
The new `--clamp-mtime` option will change the behavior of `--mtime` to only
use the time specified if the file mtime is newer than the given time.
The `--clamp-mtime` option can only be used together with `--mtime`.

Typical use case is to make builds reproducible: to loose less
information, it's better to keep the original date of an archive, except for
files modified during the build process. In that case, using a reference
(and thus reproducible) timestamps for the latter is good enough. See
<https://wiki.debian.org/ReproducibleBuilds> for more information.
