Several OVS structs contain embedded named unions, like this:
struct {
...
union {
...
} u;
};
C11 standardized a feature that many compilers already implemented
anyway, where an embedded union may be unnamed, like this:
struct {
...
union {
...
};
};
This is more convenient because it allows the programmer to omit "u."
in many places. OVS already used this feature in several places. This
commit embraces it in several others.

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 allows other libraries to use util.h that has already
defined NOT_REACHED.

Some of the uses for the formerly supported regular expression constraints
were simply to limit values to those in a set of allowed values.
This commit adds support for that kind of simple enumeration constraint.
Regular expression constraints have caused nothing but trouble due to the
lack of a ubiquitous regular expression library. PCRE is *almost*
everywhere, but it has different versions, and different features, and
different bugs, in different places. It is more trouble than it is worth.
So this commit drops support.
It is natural to write "abc" in place of ["set",["abc"]] and vice versa.
I cannot think of a reason not to support this, and it can make reading
and writing OVSDB files and transactions easier, so support it.
A "min" value greater than 1 is problematic for the database. There is no
reasonable way to synthesize a default value for such a column: keys in a
set or map must unique, so the database cannot, say, simply set a set of
3 or more integers to [0, 0, 0].
This should have no effect on the vswitch in practice because it does not
have any columns that require more than one element.
