I believe that THD needs to be opaque, but there could be a wrapper
thd_charset(THD*).

I aped the Makefile.am and plug.in from storage/archive (the only
storage engine plugin that consists of multiple compilation units),
and my plug.in contains this line:
MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS(innobase, [handler/ha_innodb.cc])
I guess that the definitions are hidden behind some #ifdef MYSQL_SERVER.
I replaced -DMYSQL_SERVER with -DMYSQL_DYNAMIC_PLUGIN in the plugin build.

I'm glad to read that you intend to make ndb pluggable. More pressure
to open up enough interfaces. :-)
