Update to 2.4.10

Changelog:

from 2.4.9 to to 2.4.10
- fixing libdar about dar_manager database corruption that occurred when
  deleting the first archive of a base containing a plain file only
  existing in that first archive.
- Added code to cleanup databases instead of aborting and reporting
  that previously described type of database corruption.
- Added feature when comparing archive with filesystem in order to report
  the offset of the first difference found in a file. This was necessary to
  help solving the following bug:
- fixed bug in sparse file detection mechanism that could lead in some very
  particular (and rare) situations to the loss of one byte from file being
  saved. In that case testing the archive reported a CRC error for that
  file. So if you keep testing achives in your backup process and have not
  detect any problem, you can then keep relying on your old backups. This
  bug also expressed when merging archives: dar aborted and reported that a
  merged file had a different CRC than the one stored in the archive of
  reference.

from 2.4.8 to 2.4.9
- fixed bug: during differential backup dar saved unchanged hard linked inode
  when a hard link on that inode was out of the -R root directory. This also
  has the effect to always save files with long names on NTFS filesystems (!)
- Adapted patch provided by Kevin Wormington (new messages displayed)
- Fixed syntax error in configure script about execinfo detection
- Removed unused AM_ICONV macro from configure script
- fixed bug met under Cygwin when auxiliary test command failed to link when
  libgcrypt was not available.
- updated mini-howto by Grzegorz Adam Hankiewicz
- updating French message translations
- restricted security warning for plain files and hard linked plain files
- fixed display bug in dar_cp when manipulating files larger than 2 GB
- fixed SEGFAULT met when adding to a dar_manager database an archive which
  base name is an empty string
- improved error message, reporting the -B included file in which a syntax error
  has been met
- modified dar_manager database to consider both ctime and mtime as timestamp
  value for data of saved files. This suppresses the warning about badly ordered
  archives in database when at some files have been restores from a old
  backup.

from 2.4.7 to 2.4.8
- documentation fixes and updates
- improved database listing efficiency
- reduced memory usage of the caching layer in libdar
- fixed self reported bug caused by memory allocation failure
- fixed a SIGSEGV caused by double free in dar_xform when syntax error is
  met on command-line
- dar_xform was not able to properly transform archive generated by dar older
  than release 2.4.0
- fixed bug that lead dar be unable to remove a directory at restoration time
- replaced old remaining "bcopy" occurrence by a call to memcpy
- fixed compilation warning under ArchLinux
- fixed crash met while creating a backup with on-fly isolation
- fixed libdar behavior when reading a strongly corrupted encrypted archive

from 2.4.6 to 2.4.7
- fixing memory allocation bug in crc class, that lead glibc aborting dar
- reviewed code and replaced some remaining occurences of bzero/bcopy by
  their recommended replacement version
- fixed compilation problem under Solaris
- fixed bug that could lead a file to be wrongly reported as different from the
  one on filesystem, when that file has been changed while it was saved, then
  saved a second time but has its size modified since the first time it was
  saved.

from 2.4.5 to 2.4.6
- fixed bug met while interrupting compressed archive creation, the resulting
  archive was only readable in --sequential-read mode
- fixed bug met while reading an interrupted archive in sequential reading
  mode. It lead dar to not release some objects from memory at the end of
  the operation, which displayed an ugly error message from libdar selfcheck
  routine.
- fixed message reporting unknown system group when converting gid to name
  (was reporting unknow "user" instead of unknown "group")
- removing the $Id:$ macro from file as we moved from CVS to GIT
- updating package to distribute Patrick Nagel's scripts and documentation
- updated URL pointing to Patrick Nagel's web site
- updating documentation describing how to get source code from GIT (no more
  from CVS)
- fixed typo in configure.ac
- added info on how to build a brand-new dar tarball from source in GIT
- modifies the end of messages shown by -h option to point to man page for
  more _options_ rather than _details_
- replaced &minus; in the HTML generated documentation by a standard ASCII dash
- fixed alignement bug in CRC calculation that lead libdar based application to
  crash on sparc-based systems.

from 2.4.4 to 2.4.5
- updated sample scripts to be compatible with dar's --min-digit option
- added missing included file to be able to compile with gcc-4.7.0
- removing an unused variable in filtre.cpp
- fixed a display bug when comparing archive with filesystem, leading to a
  segmentation fault (%S in place of %i in mask)
- fixed bug leading dar to not restore some directories from differential
  backups when they are absent in the filesystem
- fixed bug that show a "uncaught exception" message at the end of archive
  listing for dar shared binaries only, compiled in infinint mode, under
  ArchLinux
- updated the configure script to link with libexecinfo when available
- added possibility to disable the use of execinfo in libdar thanks to the
  new --disable-execinfo option for the ./configure script
- added Andreas Wolff patch to fix bug under Cygwin (segfault on program
  termination).

from 2.4.3 to 2.4.4
- fixed man pages in the NAME section: added whatis entry
- fixed segfault: in the internal error reporting code (delete[] in place of
  free())
- fixed bug: dar_manager was not able to read properly the latest generated
  databases version when having Extended Attributes recorded for some files
- avoided reporting unreleased memory block when compilation optimization
  have been used (dar, dar_manager, dar_cp, dar_slave, dar_xform do all
  reported unreleased memory when gcc optimization was used in "infinint" mode)

from 2.4.2 to 2.4.3
- fixed absurd compilation warning about possibly uninitialized variable
- added -ai switch to dar_manager to disable warning about improper file order
  in database.
- fixed bug met while changing order of archives in a dar_manager database
- avoiding concurrent use of -p and -Q options, error message shown in that
  situation.
- modified slice overwriting detection code to use a single atomic system call
  to create a new slice
- replaced delete by delete[] for conversion routine of user/group to uid/gid
- added the possibility to disable speed optimization for large directories
- added memory troubleshooting option --enable-debug-memory
- simplified class CRC implementation
- fixed failed memory release upon exception thrown in class deci
- modified tlv, tlv_list classes and ea_filesystem routines to not require
  any corresponding temporary objects in libdar (saves a few new/delete calls)
- fixed silent bug in tlv class: due to the absence of copy constructor and
  destructor, some memory was not released and referred after the corresponding
  object's destruction
- modified generic_file class to avoid temporary crc objects
- fixed bug in header class that lead unreleased field (this class lacked a
  destructor), memory impact was however little: 10 bytes per slice
- fixing bug in class tlv: unreleased memory
- added protection code in class deci to properly release memory against
  exception thrown from called routines when user interrupts the operation.
- replace previous internal stack report code by backtrace()/backtrace_symbols()
- complete change of the implementation of the 'special-alloc' feature:
  the old code eat too much memory not to be adapted to new features added
  in release 2.4.0. This new implementation also bring some speed improvement

from 2.4.1 to 2.4.2
- fixing bug met when reading an archive in sequential-read mode
- fixing bug while filtering in sequential-read mode
- fixing backward compatibility in dar_manager with old archives (wrong dates
  for deleted files).
- fixing compilation problem on certain systems (missing #include statement)
- fixing documentation syntax and spelling
Updated archivers/dar to 2.4.10
