In the past a single AioContext was used for block I/O and it was
fetched using blk_get_aio_context(). Nowadays the block layer supports
running I/O from any AioContext and multiple AioContexts at the same
time. Remove the dma_blk_io() AioContext argument and use the current
AioContext instead.
This makes calling the function easier and enables multiple IOThreads to
use dma_blk_io() concurrently for the same block device.

Currently we handle the 'dumpdtb' machine sub-option ad-hoc in every
board model that has an FDT. It's up to the board code to make sure
it calls qemu_fdt_dumpdtb() in the right place.
This means we're inconsistent and often just ignore the user's
command line argument:
* if the board doesn't have an FDT at all
* if the board supports FDT, but there happens not to be one
present (usually because of a missing -fdt option)
This isn't very helpful because it gives the user no clue why their
option was ignored.
However, in order to support the QMP/HMP dumpdtb commands we require
now that every FDT machine stores a pointer to the FDT in
MachineState::fdt. This means we can handle -machine dumpdtb
centrally by calling the qmp_dumpdtb() function, unifying its
handling with the QMP/HMP commands. All the board code calls to
qemu_fdt_dumpdtb() can then be removed.
For this commit we retain the existing behaviour that if there
is no FDT we silently ignore the -machine dumpdtb option.

Locking the memory without MCL_ONFAULT instantly prefaults any mmaped
anonymous memory with a write-fault, which introduces a lot of extra
overhead in terms of memory usage when all you want to do is to prevent
kcompactd from migrating and compacting QEMU pages. Add an option to
only lock pages lazily as they're faulted by the process by using
MCL_ONFAULT if asked.

qtest_send_prefix never actually sent something over the chardev, all
it does is print the timestamp to the QTEST_LOG when enabled. So
rename the function, make it static, remove the unused CharDev and
simplify all the call sites by handling that directly with
qtest_send (and qtest_log_send).

By changing the way the main QEMU event loop is invoked, I inadvertently
changed the BQL status of exit notifiers: some of them implicitly
assumed they would be called with the BQL held; the BQL is however
not held during the exit(status) call in qemu_default_main().
Instead of attempting to ensuring we always call exit() from the BQL -
including any transitive calls - this change adds a BQL lock guard to
qemu_run_exit_notifiers, ensuring the BQL will always be held in the
exit notifiers.
Additionally, the BQL promise is now documented at the
qemu_{add,remove}_exit_notifier() declarations.
