Currently, the HDA device tries to sync itself with the QEMU audio backend by waiting for the guest driver to handle buffer completion interrupts. This causes the backend to often read too much data from the device, as well as running out of data whenever the guest takes too long to handle the interrupt. According to the HDA specification, the guest is also not required to use interrupts, but can also sync itself by polling the LPIB registers. This patch will introduce high frequency (1000Hz) timers that interface with the device and allow for much smoother emulation of the LPIB registers. Since the timing is now provided by these timers, the need to wait for buffer completion interrupts also ceases.

This commit removes the PYTHON_UTF8 workaround. The problem with setting LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8 is that the en_US.UTF-8 locale might not be available. In this case setting above locales results in build errors even though another UTF-8 locale was originally set [1]. The only stable way of fixing the encoding problem is by specifying the encoding in Python, like the previous commit does.

Python 2 happily reads UTF-8 files in text mode, but Python 3 requires either UTF-8 locale or an explicit encoding passed to open(). Commit d4e5ec87 fixed this by setting the en_US.UTF-8 locale. Falls apart when the locale isn't be available. Matthias Maier and Arfrever Frehtes Taifersar Arahesis proposed to use binary mode instead, with manual conversion from bytes to str. Works, but opening with an explicit encoding is simpler, so do that. Since Python 2's open() doesn't support the encoding parameter, we need to suppress it with a version check.

It often happens that just a few discriminator values imply extra data in a flat union. Existing checks did not make possible to leave other values uncovered. Such cases had to be worked around by either stating a dummy (empty) type or introducing another (subset) discriminator enumeration. Both options create redundant entities in qapi files for little profit. With this patch it is not necessary anymore to add designated union fields for every possible value of a discriminator enumeration.

In its current form, qdict_flatten() removes all entries from nested QDicts that are moved to the root QDict. It is completely sufficient to remove all old entries from the root QDict, however. If the nested dicts have a refcount of 1, this will automatically delete them, too. And if they have a greater refcount, we probably do not want to modify them in the first place. The latter observation means that it was currently (in general) impossible to qdict_flatten() a shallowly cloned dict because that would empty nested QDicts in the original dict as well. This patch changes this, so you can now use qdict_flatten(qdict_shallow_clone(dict)) to get a flattened copy without disturbing the original.

The xen pci_assign_dev_load_option_rom() currently creates a RAM memory region with memory_region_init_ram_nomigrate(), and then manually registers it with vmstate_register_ram(). In fact for its only callsite, the 'owner' pointer we use for the init call and the '&dev->qdev' pointer we use for the vmstate_register_ram() call refer to the same object. Simplify the function to only take a pointer to the device once instead of twice, and use memory_region_init_ram() which automatically does the vmstate register for us.
