Upstream now provides msgpack as two separate distributions: a C version
with the traditional libmsgpackc.so library, and a header-only C++
version.
devel/msgpack is now devel/msgpack-c and devel/msgpack-cxx, and its
consumers now point to one or both. Note that it is entirely possible
for both to be required. PORTREVISION bump for all consumers.
In my testing, it's not clear that the MSGPACK option in the mariadb
ports actually does anything. I don't think mariadb is actually linking
against msgpack, even before this commit.
