Remove config-devices.mak on 'make clean'
Our dependency mechanism works like this:
* on first build there is neither a .o nor a .d
* we create the .d as a side effect of creating the .o
* for rebuilds we know when we need to update the .o,
which also updates the .d
This system requires that you're never in a situation where there is
a .o file but no .d (because then we will never realise we need to
build the .d, and we will not have the dependency information about
when to rebuild the .o).
This is working fine for our object files, but we also try to use it
for $TARGET/config-devices.mak (where the dependency file is
in $TARGET-config-devices.mak.d). Unfortunately "make clean" doesn't
remove config-devices.mak, which means that it puts us in the
forbidden situation of "object file exists but not its .d file".
This in turn means that we will fail to notice when we need to rebuild:
mkdir build/depbug
(cd build/depbug && '../../configure')
make -C build/depbug -j8
make -C build/depbug clean
echo "CONFIG_CANARY = y" >> default-configs/arm-softmmu.mak
make -C build/depbug
grep CANARY build/depbug/aarch64-softmmu/config-devices.mak
The CANARY token should show up in config-devices.mak but does not.
Fix this bug by making "make clean" delete the config-devices.mak files.
config-all-devices.mak doesn't have the same problem since it has
no .d file, but delete it too, since it is created by "make" and
logically should be removed by "make clean".
(Note that it is important not to remove config-devices.mak until
after we have recursively run 'make clean' in the subdirectories.)

cpus.c: Use pthread_sigmask() rather than sigprocmask()
On Linux, sigprocmask() and pthread_sigmask() are in practice the

qemu-iotests: Fix regression in 136 on aio_read invalid
Commit
093ea232 removed the ability for aio_read and aio_write
to artificially inflate the invalid statistics counters for
block devices, since it no longer flags unaligned offset or
length. Add 'aio_read -i' and 'aio_write -i' to restore
the ability, and update test 136 to use it.

qemu-iotests: Some more write_zeroes tests
This covers some more write_zeroes cases which are relevant for the
recent qcow2 optimisations that check the allocation status of the
backing file for partial cluster write_zeroes requests.
This needs to be separate from 034 because we can only support qcow2 in
this test case for multiple reasons: We check the allocation status
after write_zeroes with 'qemu-img map' and the optimised behaviour that
produces zero clusters is only implemented in qcow2; second, the map

use 512 byte clusters which aren't supported for formats like qed.

Move channel declarations that only need SubchDev from cpu.h
to css.h, to make more channel users independent of cpu.h.

Memory barriers are needed also by Xen and, when the ioeventfd
bugs are fixed, by TCG as well.
sysemu/kvm.h is not anymore needed in sysemu/dma.h, move it to

hw: cannot include hw/hw.h from user emulation
All qdev definitions are available from other headers, user-mode

By considering system emulation only, it is simpler to disentangle
