[PATCH 4/7] tcg/module: add some infrastructure for modular tcg.

[Gerd Hoffmann <kraxel@redhat.com>]

Create tcg-module.[ch] files, with struct TCGModuleOps, empty for now.

Followup patches will add function pointers to the struct and stub
functions to tcg-module.c.  That will effectively will switch stubs from
compile-time to runtime, which is needed to build tcg as module.
