qemu: upgrade to 1.3.0

remove-hardcoded-libexec.patch: removed
    - included in the new version

qemu-vmware-vga-depth.patch: removed
    - doesn't apply anymore
    - the problem addressed by the patch is fixed by
reverting commit 1f202568e0553b416483e5993f1bde219c22cf72

Revert-vmware_vga-Add-back-some-info-in-local-state-.patch:
    - VMware VGA requires that the depth presented to the guest
to be the same as the Display Surface depth in order to do not
corrupt the display
    - do not cache the DS depth (the depth might change)
    - revert commit 1f202568

- QEMU now uses pixman (DEPENDS += "pixman")
- rearrange the recipe in order to mimic the bitbake flow
- update both variants (.tar.bz2, git)

+In native builds, qemu can fail to find zlib development files in the native 
+sysroot and the build machine might not have zlib-dev packages installed.
+
+Add CFLAGS to qemu's CFLAGS which in the native case means BUILD_CFLAGS are
+added and files in the sysroot can be found.
