Import YAML-Parser yaml-cpp

  Version: tags/yaml-cpp-0.6.2
  License: MIT

yaml-cpp requires c++11 and since yaml-cpp 0.6 there is no dependency on
boost anymore.

A YAML parser is needed for the ClangTools plugin to parse exported
diagnostics from clang-tidy/clazy:

  $ clang-tidy -export-fixes=/tmp/tidy.yaml source.cpp

The imported source is stripped of unneeded files as documented with

  src/libs/3rdparty/yaml-cpp/patches/0001-yaml-cpp-Strip-unneeded-sources.patch
  (generated with "git format-patch -D")
