The range of IDs should be [base, base + n_ids),
but id_pool_alloc_id() allocated the range of IDs is [base, base + n_ids].
And id_pool_free_id() cannot free the ID value base correctly.

This simple change makes id-pool to always allocate the
lowest possible id from the pool. No any other code affected
because, actually, there is no users of 'id_pool_free_id' in
OVS.
This behaviour of id-pool will be used in the next patch.

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.

This provides the bulk of the ofproto side of support for
OpenFlow 1.5 group messages. It provides for encoding and decoding
of updated group mod and group desc reply messages. This includes
a new bucket format and their properties.
Open Flow 1.5 Groups also have properties but as no non-experimenter
properties are defined this patch does not provide parsing or encoding
of group properties.

id_pool_alloc_id() was created by breaking out the recirculation
allocation code. As it is now a library call it makes sense to remove
the restriction that id 0 is reserved.

Refactor the lock-free portion of the recirculation id allocator
into stand-alone id pool. This is in preparation for re-using
that portion to allocate bucket ids which are part of (draft)
OpenFlow 1.5 groups.
