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.

This adds parameters to virtio-rng-pci to allow rate limiting the entropy a
guest receives. An example command line:
$ qemu -device virtio-rng-pci,max-bytes=1024,period=1000
Would limit entropy collection to 1Kb/s.

The Linux kernel already has a virtio-rng driver, this is the device
implementation.
When the guest asks for entropy from the virtio hwrng, it puts a buffer
in the vq. We then put entropy into that buffer, and push it back to
the guest.

aliguori: converted to new RngBackend interface
aliguori: remove entropy needed event
aliguori: fix migration
This backend talks EGD to a CharDriverState. A typical way to invoke this would
be:
qemu -chardev socket,host=localhost,port=1024,id=chr0 \
-object rng-egd,chardev=chr0,id=egd0 \
-device virtio-rng-pci,rng=egd0

The filename can be overridden but it expects a non-blocking source of entropy.
A typical invocation would be:
qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0
This can also be used with /dev/urandom by using the command line:
qemu -object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-pci,rng=rng0

v2 -> v3
- bug fix in rng-random (Paolo)
This will create a new QOM object in the '/objects' path. Note that properties
are set in order which allows for simple objects to be initialized entirely
with this option and then realized.
This option is roughly equivalent to -device but for things that are not

Starting with commit 1c380f9460 dma
transfers can actually fail. This patch makes ehci keep track
of the busmaster bit in pci config space, by setting/clearing the
dma_context pointer. Attempts to dma without context will result
in raising HSE (Host System Error) interrupt and stopping the host
controller.
This patch fixes WinXP not booting with a usb stick attached to ehci.
Root cause is seabios activating ehci so you can boot from the stick,
and WinXP clearing the busmaster bit before resetting the host
controller, leading to ehci actually trying dma while it is disabled.

Windows links interrupt qtd-s in circles, which means that when interrupt
endpoints return USB_RET_ASYNC, combined with the recent
"ehci: Retry to fill the queue while waiting for td completion" patch,
we keep adding the tds to the queue over and over again, as we detect the
circle from fill_queue, but we call it over and over again ...
This patch fixes this by changing the circle detection to also detect
circling into tds already queued up previously.

This avoids the q->qtdaddr == p->qtdaddr asserts we have triggering, when
a queue contains multiple completed packages when we cancel the queue.
I triggered this with windows7 + async interrupt endpoint handling (*)
+ not detecting circles in ehci_fill_queue() properly, which makes the qtd
validation in ehci_fill_queue fail, causing cancellation of the queue on every
mouse event ...
*) Which is not going upstream as it will cause loss of interrupt events on
migration.
