I420ToNV21 passes the wrong dst_stride_y when it calls I420ToNV12; parameter 8 (convert_from.cc:448) is src_stride_y but should be dst_stride_y.  This causes image corruption when converting I420 -> NV21 with mismatched luminance strides.

Remove assumption on absolute paths in java_cpp_enum.py.

In java_cpp_enum.py there were assumptions on 'build' being
a component of the absolute path of the script invoking the
script. This leads to problems when other projects are using
the Chromium build toolchain (in this case libyuv), where
the script invoking GYP is located in the root of the project
dir (https://chromium.googlesource.com/libyuv/libyuv/+/master/gyp_libyuv).

fpic, with stack frames on 32 bit x86 with clang.
Previously they were enabled based on _DEBUG but that macro
is not set in some build systems.  This CL adds DEBUG macro as
