Updated p5-CPAN-Meta to 2.150010.

2.150010  2016-08-18 12:10:08-04:00 America/New_York

  [FIXED]

  - the YAML and JSON backend variables are ignored when building/testing the
    perl core itself, where non-core backends are not yet installed.

  [CHANGED]

  - Added "use warnings" to Parse::CPAN::Meta

2.150009  2016-07-02 21:07:49-04:00 America/New_York (TRIAL RELEASE)

  [FIXED]

  - Fixed used of Encode in Parse::CPAN::Meta::load_json_string
    (Cherry picked from Parse::CPAN::Meta 1.4422)

2.150008  2016-06-28 17:01:03-04:00 America/New_York (TRIAL RELEASE)

  [ADDED]

  - Merged Parse::CPAN::Meta 1.4420 into this distribution

2.150007  2016-06-28 03:48:16-04:00 America/New_York (TRIAL RELEASE)

  [FIXED]

  - The cloning routine would raise an error on expected types when it
    previously would stringify.  The old behavior is restored.

2.150006  2016-06-23 20:05:46-04:00 America/New_York (TRIAL RELEASE)

  [FIXED]

  - CPAN::Meta::Prereqs now fully accepts phases and types starting with 'x_'.
    New 'phases' and 'types_in' interfaces have been added.

  - No longer relies on JSON backend for data structure cloning. This is
    much faster than using JSON::PP.

  [TESTS]

  - The 'extra_mappings' feature for meta merging is now tested and
    documented.

  - During tests, delete new environment variables added by
    Parse::CPAN::Meta 1.4418

  [SPEC]

  - Clarifies acceptable values for booleans

  - Cleaned up text and links of historical specs.
