Implementation of OBJECT_OFFSETOF() for non-GNUC compilers like MSVC
causes "uninitialized variable" warnings. Since OBJECT_OFFSETOF() is
indirectly used through all the *_FOR_EACH() (through ASSIGN_CONTAINER()
and OBJECT_CONTAINING()) macros, the OVS build
on Windows gets littered with "uninitialized variable" warnings.
This patch attempts to workaround the problem.

This helps about 1% in TCP_CRR performance test. However, this also
helps by clearly showing the classifier_lookup() cost in perf reports
as one item.
This also cleans up the flow/match APIs from functionality only used
by the classifier, making is more straightforward to evolve them
later.

This commit makes macro function "ASSIGN_CONTAINER()" evaluates
to "(void)0". This is to avoid the 'clang' warning: "expression
result unused", since most of time, the final evaluated value
is not used.

It seems that 'clang' compiler applies strict protection on pointer
dereference. And it causes unexpected execution in macro functions
like "HMAP_FOR_EACH()" and unit test failures. This commit fixes
this issue and pass all unit tests.
