On SIGP initial cpu reset, we exchange the wrapping key while other VCPUs are running. Bad! 3. It is simply wrong. According to the Pop, a reset happens only during a clear reset.

2015-10-21s390x: machine reset function with new ipl cpu handlingDavid Hildenbrand
Current implementation depends on the order of resets getting triggered. If a cpu reset is triggered after the ipl device reset, the CPU is stopped and the VM will not run. In fact, that hinders us from converting the ipl device into a TYPE_DEVICE. Let's change that by manually configuring the ipl cpu during a system reset, so we have full control and can demangle that code. Also remove the superflous cpu parameter from s390_update_iplstate on the way.

2015-10-20coroutine: move into libqemuutil.a libraryDaniel P. Berrange
The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

2015-10-20osdep: add qemu_fork() wrapper for safely handling signalsDaniel P. Berrange
When using regular fork() the child process of course inherits all the parents' signal handlers. If the child then proceeds to close() any open file descriptors, it may break some of those registered signal handlers. The child generally does not want to ever run any of the signal handlers that the parent may have installed in the short time before it exec's. The parent may also have blocked various signals which the child process will want enabled. This introduces a wrapper qemu_fork() that takes care to sanitize signal handling across fork. Before forking it blocks all signals in the parent thread. After fork returns, the parent unblocks the signals and carries on as usual. The child, however, resets all the signal handlers back to their defaults before it unblocks signals. The child process can now exec the binary in a "clean" signal environment.
