Update List-Util to CPAN version 1.25

  [DELTA]

1.25 -- Sat Mar 24 13:10:13 UTC 2012

  * Restore back-compat. to perl 5.6 (thanks to Zefram)

1.24 -- Thu Mar 22 18:10:10 UTC 2012

  * Update to 1.24 release version (no other changes since 1.23_04).

1.23_04 -- Sat Mar 10 00:16:16 UTC 2012

  * RT#72700 Fix off-by-two on string literal length

1.23_03 -- Tue Sep 14 10:09:59 CDT 2010

  * Min perl version supported for build is not 5.008
  * Dropped the pure-Perl implementation of both Scalar::- and List::Util.
  * RT#61118 Fix assumption in sum() that once magic, always magic

1.23_02 -- Tue Mar 30 11:09:15 CDT 2010

  * Fix first() and reduce() to check the callback first; &first(1) is now illigal. [gfx]
  * Fix reduce() to allow XSUB callbacks [gfx]
  * Fix first() to allow XSUB callbacks [gfx]
  * Resolve RT #55763: tainted() doesn't do SvGETMAGIC(sv) [gfx]
  * define CvISXSUB so older perl versions will still compile

1.23_01 -- Mon Mar 22 08:24:11 CDT 2010

  * Add failing tests; SVt_RV is not directly SvROK [gfx]
  * Implement openhandle() in XS (with extra tests) [gfx]
  * Modernize *.pm [gfx]
  * Modernize ListUtil.xs [gfx]
  * Add ppport.h [gfx]
  * Fix an overloading issue on sum(), and add tests for overloading [gfx]
  * Small tweaks for minstr()/maxstr() [gfx]
  * Optimize dualvar() [gfx]
  * Use sv_copypv() instead of SvPV() and sv_setpv() [gfx]
  * avoid non-portable warnings
