build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.
Toolchain support is just too sparse, in particular llvm-gcc is totally
broken.
This patch uses a surprisingly low-tech approach: a static library.
Symbols in a static library are always overridden by symbols in an
object file. Furthermore, if you place each function in a separate
source file, object files for unused functions will not be taken in.
This means that each function can use all the dependencies that it needs
(especially QAPI stuff such as error_setg).
Thus, all stubs are placed in separate object files and put together in
a static library. The library then is linked to all programs.

usb: Fix (another) bug in usb_packet_map() for IOMMU handling
Elements in qemu SGLists can cross IOMMU page boundaries. So, in commit
39c138c8420f51a7da7b35233a8d7400a0b589ac "usb: Fix usb_packet_map() in the
presence of IOMMUs", I changed usb_packet_map() to split up each SGList
element on IOMMU page boundaries and each resulting piece of qemu's memory
space separately to the iovec the usb code uses internally.
That was correct in concept, but the patch has a bug. The 'base' variable
correctly steps through the dma address of each piece, but then we call
the dma_memory_map() function on the base address of the whole SGList
element every time.
This patch fixes at least one problem using XHCI on the pseries guest
machine. It didn't affect OHCI because that doesn't use usb_packet_map().
In theory it also affects EHCI, but we haven't observed that in practice.
I think the transfers were small enough on EHCI that they never crossed an
IOMMU page boundary in practice.

fix live migration
Commit
1c380f9460522f32c8dd2577b2a53d518ec91c6d breaks live migration.
DMA stops working for ehci (and probably for any pci device) after
restoring the guest because the bus master region never gets enabled.
Add code doing that after loading the pci config space from vmstate.

virtio-serial-bus: post_load send_event when vm is running
Alexander Larsson found irq injection to Windows guests stopped after a
migration. The symptom was the mouse stopped working.
Reproduction steps are:
1. On src, start qemu with a virtio-serial port without any backend
2. On dest, start qemu with a virtio-serial port with a backend
3. Migrate.
Upon migration, the older code detected the change in backend connection
status, and sent a notification to the guest. However, it's not
guaranteed that the apic is ready to inject irqs into the guest, and the
irq line remained high, resulting in any future interrupts going
unnoticed by the guest as well.
Add a new timer based on vm_clock for 1 ns in the future from post_load
to do the event send in case host_connected differs between migration
source and target.

In QEMU they are both connected to hardware interrupt 0, the CBUS UART

the irq array in QEMU includes the software interrupts, hence

aio: use g_slice_alloc() for AIOCB pooling
AIO control blocks are frequently acquired and released because each aio
request involves at least one AIOCB. Therefore, we pool them to avoid
heap allocation overhead.
The problem with the freelist approach in AIOPool is thread-safety. If
we want BlockDriverStates to associate with AioContexts that execute in
multiple threads, then a global freelist becomes a problem.
This patch drops the freelist and instead uses g_slice_alloc() which is
tuned for per-thread fixed-size object pools. qemu_aio_get() and
qemu_aio_release() are now thread-safe.
Note that the change from g_malloc0() to g_slice_alloc() should be safe
