Update 0.25 to 0.27
-------------------
0.27    2015-03-27 22:10 UTC
        + Chg : The new environment variable to enable thread tests on older
                perls is PERL_FORCE_TEST_THREADS. Note that this variable
                should only be turned on by authors.
        + Fix : Segfaults when the module is loaded by several threads (or
                Windows emulated processes) ran in parallel.
        + Fix : Memory leak with the uid() feature.
        + Fix : Update the Windows ActivePerl + gcc 3.4 workaround for
                ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting
                and feedback on this issue.
        + Fix : reap(), localize(), localize_elem() and localize_delete()
                will again work correctly on perl 5.19.4+ when the debugger
                is enabled.
        + Fix : Silence some compiler warnings.

0.26    2015-03-12 23:30 UTC
        + Fix : [RT #100264] : Don't use CvPADLIST on XSUBs
                Thanks Father Chrysostomos for reporting and contributing a
                patch.
        + Fix : Be really compatible with the optional OP_PARENT feature.
