block: Fix direct use of protocols as driver for bdrv_open()
bdrv_open_common() implements direct use of protocols by copying the
pre-opened BlockDriverStates to bs using bdrv_swap(). It did however
first set some fields in bs, which end up in file after the swap. When
bdrv_open() destroys file, it appears to be open, and because it isn't,
qemu could segfault while trying to close it.
Reorder the operations to return immediately in such cases so that file
is correctly detected as closed.

qcow2: Gather clusters in a looping loop
Instead of just checking once in exactly this order if there are
dependendies, non-COW clusters and new allocation, this starts looping
around these. This way we can, for example, gather non-COW clusters after
new allocations as long as the host cluster offsets stay contiguous.
Once handle_dependencies() is extended so that COW areas of in-flight
allocations can be overwritten, this allows to continue with gathering
other clusters (we wouldn't be able to do that without this change
because we would have missed a possible second dependency in one of the
next clusters).
This means that in the typical sequential write case, we can combine the
COW overwrite of one cluster with the allocation of the next cluster as
soon as something like Delayed COW gets actually implemented. It is only
by avoiding splitting requests this way that Delayed COW actually starts
improving performance noticably.

qcow2: Handle dependencies earlier
Handling overlapping allocations isn't just a detail of cluster
allocation. It is rather one of three ways to get the host cluster
offset for a write request:
1. If a request overlaps an in-flight allocations, the cluster offset
can be taken from there (this is what handle_dependencies will evolve
into) or the request must just wait until the allocation has
completed. Accessing the L2 is not valid in this case, it has
outdated information.
2. Outside overlapping areas, check the clusters that can be written to
as they are, with no COW involved.
3. If a COW is required, allocate new clusters
Changing the code to reflect this doesn't change the behaviour because
overlaps cannot exist for clusters that are kept in step 2. It does
however make it easier for later patches to work on clusters that belong
to an allocation that is still in flight.

allocated - due to zero size the allocator doesn't increment the next
available RAMBlock offset.
Also convert __FUNCTION__ to __func__ while we're touching this code.
There are no other __FUNCTION__ instances in pci.c anymore.

pci_bridge: Remove duplicate IRQ swizzle function
pci_bridge_dev_map_irq_fn() is identical to pci_swizzle_map_irq_fn(),
which is now the default for all PCI bridges. We can therefore remove
this function and the pci_bridge_map_irq() call that used it.

pci_bridge: Use a default map_irq function
The PCI bridge spec defines a default swizzle for translating INTx
IRQs from secondary bus to primary. Use this by default for any
bridge that doesn't set a function.

pci: Fix INTx routing notifier recursion
For some reason we recurse to fire the INTx routing notifier for each
child of a bus, for each possible device of a bus. That means that if
we add a root port, the notifier gets called for that bridge 256
times. If we add an upstream switch behind that root port, 256^2. But
of course we need a downstream switch, 256^3. This starts to be
noticeable. Stop the insanity.

pci_bridge: drop formatting from source
We use the same formatting for all files, it
doesn't make sense to have formatting directives only
in pci bridge header.
