PyModule_AddObject() may fail and it doesn't steal references
in this case. The error condition should be handled to avoid
possible memory leaks.
And while it's not strictly specified if PyModule_Create may
fail, most of the examples in python documentation include
handling of a NULL case.

To easily allow both in- and out-of-tree building of the Python
wrapper for the OVS JSON parser (e.g. w/ pip), move json.h to
include/openvswitch. This also requires moving lib/{hmap,shash}.h.
Both hmap.h and shash.h were #include-ing "util.h" even though the
headers themselves did not use anything from there, but rather from
include/openvswitch/util.h. Fixing that required including util.h
in several C files mostly due to OVS_NOT_REACHED and things like
xmalloc.

The pure Python in-tree JSON parser is *much* slower than the
in-tree C JSON parser. A local test parsing a 100Mb JSON file
showed the Python version taking 270 seconds. With the C wrapper,
it took under 4 seconds.
The C extension will be used automatically if it can be built. If
the extension fails to build, a warning is displayed and the build
is restarted without the extension.
The Serializer class is replaced with Python's built-in
JSON library since the ability to process chunked data is not
needed in that case.
The extension should work with both Python 2.7 and Python 3.3+.
