[Qemu-devel] Main loop

[malc <av1474@comtv.ru>]

At http://repo.or.cz/w/qemu/malc.git?a=shortlog;h=refs/heads/mtloop you
can find the branch which refactors main execution loop somewhat, effects
include:

a. Host alarm timers are gone
b. IO thread is replaced (now Windows is supported too)

I have no means of testing the KVM/Xen bits (both are likely to be broken
by this), and since testing was only done on Linux/X86-64[1],PPC and 
Windows/i386 chances are good that something might be not so great in
BSD/Solairs/MacOS X lands.

Apart from obvious KVM bits, other things were not implemented (yet) 
either: proper VM stop/resume, GDB, etc.

Diffstat relative to c2b023b62707f5dc73497dc03f3764f145a29785 (plus
one somewhat unrelated local commit) is bellow.

[1] Linux/X86-64 was tested yesterday in the meantime the code was changed
    and might have become less stable, not sure.
