- Update to 23.4:
  * Bug in hash implementation fixed.  It was possible to get a hash
    hit at ply=2, and alter the ply=1 PV when it should be left with
    no change.  This could cause Crafty to display one move as best
    and play another move entirely.  Usually this move was OK, but it
    could, on occasion, be an outright blunder.  This has been fixed.
    The search.c code has been re-written to eliminate SearchRoot()
    entirely, which simplifies the code.  The only duplication is in
    SearchParallel() which would be messier to eliminate.  Ditto for
    quiesce.c, which now only has Quiesce() and QuiesceEvasions().
    The old QuiesceChecks() has been combined with Quiesce, again to
    eliminate duplication and simplify the code.  Stupid bug in code
    that handles time-out.  One place checked the wrong variable and
    could cause a thread to attempt to output a PV after the search
    was in the process of timing out.  That thread could back up an
    incomplete/bogus search result to the root in rare occasions,
    which would / could result in Crafty kibitzing one move but
    playing a different move.  On occasion, the move played could be
    a horrible blunder.  Minor bug caused HashStore() to lose a best
    move when overwriting an old position with a null-move search
    result.  Minor change by Tracy to lazy evaluation cutoff to speed
    up evaluation somewhat.  Old "Trojan Horse" attack detection was
    removed.  At today's depths, it was no longer needed.  New hash
    idea stores the PV for an EXACT hash entry in a separate hash
    table.  When an EXACT hit happens, this PV can be added to the
    incomplete PV we have so far so that we have the exact path that
    leads to the backed up score.  New "phash" (path hash) command to
    set the number of entries in this path hash table.  For longer
    searches, a larger table avoids path table collisions which will
    produce those short paths that end in <HT>.  If <HT> appears in
    too many PVs, phash should be increased.  The "Trojan Horse" code
    has been completely removed, which also resulted in the removal
    of the last bit of "pre-processing code" in preeval.c, so it has
    been completely removed as well.  Current search depths are such
    that the Trojan Horse code is simply not needed any longer.  A
    minor bug in TimeSet() fixed where on rare occasions, near the
    end of a time control, time_limit could be larger than the max
    time allowed (absolute_time_limit).  We never check against this
    limit until we exceed the nominal time limit.  Cleanup on the
    draw by repetition code to greatly simplify the code as well as
    speed it up.
  From 23.3:
  * Null-move search restriction changed to allow null-move searches
    at any node where the side on move has at least one piece of any
    type.  Minor bug in ValidMove() fixed to catch "backward" pawn
    moves and flag them as illegal.  This sometimes caused an error
    when annotating games and annotating for both sides.  The killer
    move array could have "backward" moves due to flipping sides back
    and forth, which would cause some odd PV displays.  Small change
    to "reduce-at-root".  We no longer reduce moves that are flagged
    as "do not search in parallel".  Check extension modified so that
    if "SEE" says the check is unsafe, the extension is not done.  We
    found this to be worth about +10 Elo.  We also now reduce any
    capture move that appears in the "REMAINING_MOVES" phase since
    they can only appear there if SEE returns a score indicating loss
    of material.  We now reduce a bit more aggressively, reducing by`
    2 plies once we have searched at least 4 moves at any ply.  I
    tried going to 3 on very late moves, but could not find any case
    where this was better, even limiting it to near the root or other
    ideas.  But reducing by 2 plies after the at least 2 moves are
    searched was an improvement.  Minor change is that the first move
    is never reduced.  It is possible that there is no hash move, no
    non-losing capture, and no killer move.  That drops us into the
    REMAINING_MOVES phase which could reduce the first move searched,
    which was not intended.  Very minor tweak, but a tweak all the
    same.
- Removed crafty-misc.tar.bz2 tarball.
  + Custom files for compiling/using crafty were added as separate Source:
    files (medtosmall.txt was removed since an upstream book.bin file is
    provided, so there is no need to compile one).
  + Files that can be downloaded from the official site were added in a new
    crafty-data.tar.bz2 tarball (bitmaps.tar.bz2 was merged in this tarball,
    added sound.zip which contains wav files for crafty, book.bin was added as
    a separate Source: since it is usually updated with each new release).
  + A script was added (update_crafty-data.sh) to easily update files in
    crafty-data.tar.bz2 using wget.
- Updated README.SuSE (from old crafty-misc.tar.bz2) to reflect the current
  status (mainly no automatic creation of user config/book files). Also renamed
  it to README.openSUSE.
- Updated crafty.rc (from old crafty-misc.tar.bz2) to fix tbpath and egtb.
- Updated crafty.6 (from old crafty-misc.tar.bz2) to fix paths and to reflect
  the current status (mainly no automatic creation of user config/book files).
- Updated make_books script (from old crafty-misc.tar.bz2) to fix compilation
  of book*.bin files and remove the compilation from medtosmall.txt).
- Rebased and updated crafty-23.2-Makefile.patch to keep libnuma requirement,
  remove -pg flag (incompatible with -fomit-frame-pointer from rpm optflags)
  and to use rpm optflags. Renamed it also to Makefile.patch.
- Rebased and updated crafty-23.2-paths.patch to apply cleanly and to fix some
  more paths. Also renamed it to paths.patch.
- Added a patch (numacompat1.patch) to add a missing include for numacompat1.h
  (fixes compilation with libnuma for x86_64).
- Added a patch (ix86.patch) to fix compilation in ix86 (based on patch from
  Archlinux).
- Added libnuma-devel as build requirement for x86_64.
- Recommend xboard package which can be used by xcrafty.
- Suggest esound-utils which can be used by crafty-speak.
