[PATCH 09/29] tcg/module: add tcg-module.[ch] infrastructure

[Gerd Hoffmann]

Add TCGModuleOps struct, empty for now, followup patches will fill it.
This struct has pointers for tcg functions which are called by core
qemu.

The struct is initialized (at compile time) with pointers to stub
functions.  When the tcg module loads it will update the function
pointers to point to the real functions instead.
