monitor: move include files to include/monitor/
build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.Toolchain support is just too sparse, in particular llvm-gcc is totallybroken.
This patch uses a surprisingly low-tech approach: a static library....
compiler: support Darwin weak references
Weakrefs only tell you if the symbol was defined elsewhere, so youneed a further check at runtime to pick the default definitionwhen needed.
This could be automated by the compiler, but it does not do it.

Allow machines to configure the QEMU_VERSION that's exposed via hardware
