2016-10-25qdict: implement a qdict_crumple method for un-flattening a dictDaniel P. Berrange
The qdict_flatten() method will take a dict whose elements are further nested dicts/lists and flatten them by concatenating keys. The qdict_crumple() method aims to do the reverse, taking a flat qdict, and turning it into a set of nested dicts/lists. It will apply nesting based on the key name, with a '.' indicating a new level in the hierarchy. If the keys in the nested structure are all numeric, it will create a list, otherwise it will create a dict. If the keys are a mixture of numeric and non-numeric, or the numeric keys are not in strictly ascending order, an error will be reported. As an example, a flat dict containing { 'foo.0.bar': 'one', 'foo.0.wizz': '1', 'foo.1.bar': 'two', 'foo.1.wizz': '2' } will get turned into a dict with one element 'foo' whose value is a list. The list elements will each in turn be dicts. { 'foo': [ { 'bar': 'one', 'wizz': '1' }, { 'bar': 'two', 'wizz': '2' } ], } If the key is intended to contain a literal '.', then it must be escaped as '..'. ie a flat dict { 'foo..bar': 'wizz', 'bar.foo..bar': 'eek', 'bar.hello': 'world' } Will end up as { 'foo.bar': 'wizz', 'bar': { 'foo.bar': 'eek', 'hello': 'world' } } The intent of this function is that it allows a set of QemuOpts to be turned into a nested data structure that mirrors the nesting used when the same object is defined over QMP.

2016-10-25qapi: don't pass two copies of TestInputVisitorData to testsDaniel P. Berrange
The input_visitor_test_add() method was accepting an instance of 'TestInputVisitorData' and passing it as the 'user_data' parameter to test functions. The main 'TestInputVisitorData' instance that was actually used, was meanwhile being allocated automatically by the test framework fixture setup. The 'user_data' parameter is going to be needed for tests added in later patches, so getting rid of the current mistaken usage now allows this. Signed-off-by: Daniel P.

Create and register a cpu_common_unrealizefn() function for the CPU device class and call cpu_exec_unrealizefn() from this function. Remove cpu_exec_exit() from cpu_common_finalize() (which mirrors init, not realize), and as x86_cpu_unrealizefn() and ppc_cpu_unrealizefn() overwrite the device class unrealize function, add a call to a parent_unrealize pointer.

2016-10-24block: More operations for meta dirty bitmapFam Zheng
Callers can create an iterator of meta bitmap with bdrv_dirty_meta_iter_new(), then use the bdrv_dirty_iter_* operations on it. Meta iterators are also counted by bitmap->active_iterators. Also add a couple of functions to retrieve granularity and count.

2016-10-24hbitmap: serializationVladimir Sementsov-Ogievskiy
Functions to serialize / deserialize(restore) HBitmap. HBitmap should be saved to linear sequence of bits independently of endianness and bitmap array element (unsigned long) size. Therefore Little Endian is chosen. These functions are appropriate for dirty bitmap migration, restoring the bitmap in several steps is available. To save performance, every step writes only the last level of the bitmap. All other levels are restored by hbitmap_deserialize_finish() as a last step of restoring. So, HBitmap is inconsistent while restoring.
