Re: [Libvir] PATCH 20/20: move the QEMU driver into libvirt.so

This is the final step to move the QEMU code out of the daemon binary and into the main libvirt.so library. Practically all of protocol.x goes away apart from a single struct representing the header - this should probably be moved into remote_protocol.x - or vica-verca. The --remote switch to the daemon is removed since its no longer needed. A single --listen switch is added to control whether the daemon opens any TCP/IP sockets or not, and a config file in /etc/sysconfig/libvirtd is provided to toggle this. By default the daemon will only listen on a UNIX socket, unless the admin edits /etc/sysconfig/libvirtd to enable TCP - whether it uses TCP or TLS is still upto the libvirtd.conf config file. The driver.c file is switched over to using virGetDomain and virGetNetwork instead of its previous temporary / nasty hack. A qemudRegister function is added to make the new implementation be registered. The daemon now registers an event loop implementation to be used by the QEMU driver. Various bits of code relating to the QEMU protocol are killed off in the qemud.c file. The remote_internal.c file is adapted so that it will handle qemu:///sesion and qemu:///system URLs as if they were qemu+unix:///session and qemu+unix:///system respectively. It is also adapted so that in the case of qemu:///session is uses $HOME/.libvirt/libvirt-sock for the UNIX domain socket path. It is also tweaked to use the abstract namespace if the first character is @ Rather than showing a huge +10000 lines, -10000 lines diff caused by moving files from qemud/ into src/, i've applied some makefile trickery to make libvirt.so compile some files out of qemud/ directly. I intend to commit it in this format, and then do the actual file names in a second commit. This will avoid mixing functional changes, with plain renames to preserve better historical CVS logs. The files to be moved from qemud/ to src/ are: driver.c -> qemud_driver.c driver.h -> qemud_driver.h conf.c -> qemud_conf.c conf.h -> qemud_conf.h bridge.c bridge.h iptables.c iptables.h uuid.c uuid.h The files to be completely deleted are: dispatch.c dispatch.h protocol.c protocol.h protocol.x qemu_internal.c qemu_internal.h NB. one feature I've just realized is missing is the autostart of the daemon when using qemu:///session in remote_internal.c. Shouldn't be much work to move the neccessary code from qemu_internal.c across.
