[PATCH 00/29] [RFC] build more i386 tcg code modular.

[Gerd Hoffmann]

This series moves a big pile of code from core qemu to the tcg module.

To allow for more fine-grained patches the first patch disables modular
tcg and the last patch re-enables it.  Alternatively we could move all
the build system changes (patches 4-8) to the end of the series and
squash them into a single patch.  Not sure which is better ...

The fundamental idea of this series is that any call from core qemu into
tcg gets routed through function pointers.  This is simliar to the way
we handle the spice module (see ui/spice-module.c).

Initially the function pointers are filled with stubs, when the tcg
module loads all function pointers are updated to point to the real
functions instead.  One side effect of this is that compile-time stubs
will become runtime-stubs.

Series overview:
   1         - disable modular tcg.
   2 =>  3   - misc small tweaks.
   4 =>  8   - build system changes.
   9 => 21   - add generic tcg function pointers.
  22 => 28   - add i386 tcg function pointers.
  29         - re-enable modular tcg.

take care,
  Gerd
