2011-12-19qom: register qdev properties also as non-legacy propertiesPaolo Bonzini
Push legacy properties into a "legacy-..." namespace, and make them available with correct types too. For now, all properties come in both variants. This need not be the case for string properties. We will revisit this after -device is changed to actually use the legacy properties.

2011-12-19qom: introduce get/set methods for PropertyPaolo Bonzini
This patch adds a visitor interface to Property. This way, QOM will be able to expose Properties that access a fixed field in a struct without exposing also the everything-is-a-string "feature" of qdev properties. Whenever the printed representation in both QOM and qdev (which is typically the case for device backends), parse/print code can be reused via get_generic/set_generic. Dually, whenever multiple PropertyInfos have the same representation in both the struct and the visitors the code can be reused (for example among all of int32/uint32/hex32).

2011-12-19qapi: protect against NULL QObject in qmp_input_get_objectPaolo Bonzini
A NULL qobj can occur when a parameter is fetched via qdict_get, but the parameter is not in the command. By returning NULL, the caller can choose whether to raise a missing parameter error, an invalid parameter type error, or use a default value. For example, qom-set could can use this to reset a property to its default value, though at this time it will fail with "Invalid parameter type". In any case, anything is better than crashing!

2011-12-19configure: Improve Xen autodetection for hosts without XenStefan Weil
With this patch, it only takes one test (instead of four) to detect that there is no Xen support at all. For most build hosts, this will reduce the time configure needs. It will also reduce noisy output in config.log. Build hosts with Xen now need up to five (instead of up to four) tests. They get improved diagnostics when Xen support fails.

2011-12-15network scripts: don't block SIGCHLD before forkingMichael Roth
This patch fixes a bug where child processes of launch_script() can misbehave due to SIGCHLD being blocked. In the case of `sudo`, this causes a permanent hang. Previously a SIGCHLD handler was added to reap fork_exec()'d zombie processes by calling waitpid(-1, ...). This required other fork()/waitpid() callers to temporarilly block SIGCHILD to avoid having the final wait status being intercepted by the SIGCHLD handler: 7c3370d4fe3fa6cda8655f109e4659afc8ca4269 Since then, the qemu_add_child_watch() interface was added to allow registration of such processes and reap only from that specific set of PIDs: 4d54ec7898bd951007cb6122d5315584bd41d0c4 As a result, we can now avoid blocking SIGCHLD in launch_script(), so drop that behavior.

2011-12-15usb: fix usb_qdev_init() error handling againStefan Hajnoczi
Commit f462141f18ffdd75847f6459ef83d90b831d12c0 introduced clean up code when usb_qdev_init() fails. Unfortunately it calls .handle_destroy() when .init() was never invoked or failed. This can lead to crashes when .handle_destroy() tries to clean up things that were never initialized. This patch is careful to undo only those steps that completed along the usb_qdev_init() code path. It's not as pretty as the unified error handling in f462141f18ffdd75847f6459ef83d90b831d12c0 but it's necessary.

2011-12-15exec.c: Fix subpage memory access to RAM MemoryRegionAndreas Färber
Commit 95c318f5e1f88d7e5bcc6deac17330fd4806a2d3 (Fix segfault in mmio subpage handling code.) prevented a segfault by making all subpage registrations over an existing memory page perform an unassigned access. Symptoms were writes not taking effect and reads returning zero. Very small page sizes are not currently supported either, so subpage memory areas cannot fully be avoided. Therefore change the previous fix to use a new IO_MEM_SUBPAGE_RAM instead of IO_MEM_UNASSIGNED. Suggested by Avi.
