ovs-thread: Add support for globally visible per-thread data.

Browse Source 
DEFINE_PER_THREAD_DATA always declared its data item as "static", meaning
that it was only directly visible within a single translation unit.
This commit adds additional forms of per-thread data that allow the data
to be accessible from multiple translation units.
