For some architectures and setups, device removal can take longer than the default 5 seconds. This results in commands such as 'virsh setvcpus' to fire timeout messages even if the operation were successful in the guest, confusing the user. This patch sets a new 10 seconds unplug timeout for PPC64 guests. All other archs will keep the default 5 seconds timeout. Instead of putting 'if PPC64' conditionals inside qemu_hotplug.c to set the new timeout value, a new function called qemuDomainGetUnplugTimeout was added. The timeout value is then retrieved when needed, by passing the correspondent DomainDef object. This approach allows for different guest architectures to have distint unplug timeout intervals, regardless of the host architecture. This design also makes it easier to modify/enhance the unplug timeout logic in the future (allow for special timeouts for TCG domains, for example). A new mock file was created to work with qemuhotplugtest.c, given that the test timeout is significantly shorter than the actual timeout value in qemu_hotplug.c. The now unused 'qemuDomainRemoveDeviceWaitTime' global can't be simply erased from qemu_hotplug.c though. Next patch will remove it properly.
