b684326e69 Use SEEK_HOLE for hole detection 
Based on patch by Pavel Raiskup.

Use SEEK_HOLE/SEEK_DATA feature of lseek on systems that support
it.  This can make archiving of sparse files much faster.

Implement the --hole-detection option to allow users to select
hole-detection method.

* src/common.h (hole_detection_method): New enum.
(hole_detection): New global.
* src/sparse.c  (sparse_scan_file_wholesparse): New function as a
method for detecting sparse files without any data.
(sparse_scan_file_raw): Rename from sparse_scan_file; with edits.
(sparse_scan_file_seek): New function.
(sparse_scan_file): Reimplement function.
* src/tar.c: New option --hole-detection

* tests/checkseekhole.c: New file.
* tests/.gitignore: Mention two test binaries.
* tests/Makefile.am: Add new tests.
* tests/testsuite.at (AT_SEEKHOLE_PREREQ): New macro.
Include sparse06.at.
* tests/sparse06.at: New test case.
* tests/sparse02.at: Force raw hole-detection method.
* tests/sparsemv.at: Likewise.
* tests/sparsemvp.at: Likewise.

* doc/tar.1: Document --hole-detection option.
* doc/tar.texi: Document hole-detection algorithms and
command-line options.
* NEWS: Document hole-detection.

Remove trailing spaces and tabs from lines, and remove
trailing empty lines from files.  This makes it a bit easier
to share code among coreutils and other projects that do this.

5354888e40 * src/buffer.c (short_read): Remove !read_full_records condition, 
which was always false on a first record and thus disabled record
size autodetection.  Thanks Ed Leaver for the patch.

* tests/sparsemv.at: Reflect changes to buffer.c.
* tests/sparsemvp.at: Likewise.
* tests/volsize.at: Likewise.
* NEWS: Update.
* THANKS: Add Ed Leaver.
