At startup enumerate datapath and port types and add this information to
the datapath_types and port_types columns in the ovsdb.
This allows an ovsdb client to query the datapath in order to determine
if certain datapath and port types exist. For example, by querying the
port_types column, an ovsdb client will be able to determine if this
instance of ovs-vswitchd was compiled with DPDK support.

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.

Casts are sometimes necessary. One common reason that they are necessary
is for discarding a "const" qualifier. However, this can impede
maintenance: if the type of the expression being cast changes, then the
presence of the cast can hide a necessary change in the code that does the
cast. Using CONST_CAST, instead of a bare cast, makes these changes
visible.
Inspired by my own work elsewhere:

This commit makes several library headers suitable for inclusion in C++.
It adds [extern "C"] guards and makes minor changes to fix casting and
keyword issues.
Many uses of "shash" or "svec" data structures really call for a "set of
strings" data type. This commit introduces such a data structure. Later
commits convert inappropriate uses of shash and svec to use sset instead.
