Subject: Initial redhat build

This patch introduces redhat build structure in redhat subdirectory. In addition,

several issues are fixed in QEMU tree:

- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm

 - As we use qemu-kvm as name in all places, this is updated to be consistent

- Man page renamed from qemu to qemu-kvm

 - man page is installed using make install so we have to fix it in qemu tree

- Added live-block-migration configuration option support

 - Downstream differentiation support

- Use "/share/qemu-kvm" as SHARE_SUFFIX

 - We reconfigured our share to qemu-kvm to be consistent with used name

- Added .gitpublish configuration file

 - Support for git publish has to be stored in repository root
