accel/tcg: Move breakpoint recognition outside translation
Trigger breakpoints before beginning translation of a TB
that would begin with a BP. Thus we never generate code
for the BP at all.
Single-step instructions within a page containing a BP so
that we are sure to check each insn for the BP as above.
We no longer need to flush any TBs when changing BPs.

linux-aio: limit the batch size using `aio-max-batch` parameter
When there are multiple queues attached to the same AIO context,
some requests may experience high latency, since in the worst case
the AIO engine queue is only flushed when it is full (MAX_EVENTS) or
there are no more queues plugged.
Commit
2558cb8dd4 ("linux-aio: increasing MAX_EVENTS to a larger
hardcoded value") changed MAX_EVENTS from 128 to 1024, to increase
the number of in-flight requests. But this change also increased
the potential maximum batch to 1024 elements.
When there is a single queue attached to the AIO context, the issue
is mitigated from laio_io_unplug() that will flush the queue every
time is invoked since there can't be others queue plugged.
Let's use the new `aio-max-batch` IOThread parameter to mitigate
this issue, limiting the number of requests in a batch.
We also define a default value (32): this value is obtained running
some benchmarks and it represents a good tradeoff between the latency
increase while a request is queued and the cost of the io_submit(2)
system call.

iothread: add aio-max-batch parameter
The `aio-max-batch` parameter will be propagated to AIO engines
and it will be used to control the maximum number of queued requests.
When there are in queue a number of requests equal to `aio-max-batch`,
the engine invokes the system call to forward the requests to the kernel.
This parameter allows us to control the maximum batch size to reduce
the latency that requests might accumulate while queued in the AIO
engine queue.
If `aio-max-batch` is equal to 0 (default value), the AIO engine will
use its default maximum batch size value.

hw/ppc/Kconfig: Add dependency PEGASOS2 -> ATI_VGA
The ATI VGA device isn't a requisite for the Pegasos2 machine
because Linux only uses the serial console; see commit
ba7e5ac18e7
("hw/ppc: Add emulation of Genesi/bPlan Pegasos II") for rationale.
Using the default devices we don't have any problem:
$ qemu-system-ppc -M pegasos2
qemu-system-ppc: standard VGA not available
But when trying to explicitly use the ATI device we get an error:
$ qemu-system-ppc -M pegasos2 -vga none -bios pegasos2.rom -device ati-vga,romfile=

replication: Properly attach children
The replication driver needs access to the children block-nodes of
it's child so it can issue bdrv_make_empty() and bdrv_co_pwritev()
to manage the replication. However, it does this by directly copying
the BdrvChilds, which is wrong.
Fix this by properly attaching the block-nodes with
bdrv_attach_child() and requesting the required permissions.
This ultimatively fixes a potential crash in replication_co_writev(),
because it may write to s->secondary_disk if it is in state
BLOCK_REPLICATION_FAILOVER_FAILED, without requesting write
permissions first. And now the workaround in
secondary_do_checkpoint() can be removed.

block: Add option to use driver whitelist even in tools
Currently, the block driver whitelists are only applied for the system
emulator. All other binaries still give unrestricted access to all block
drivers. There are use cases where this made sense because the main
concern was avoiding customers running VMs on less optimised block
drivers and getting bad performance. Allowing the same image format e.g.
as a target for 'qemu-img convert' is not a problem then.
However, if the concern is the supportability of the driver in general,
either in full or when used read-write, not applying the list driver
whitelist in tools doesn't help - especially since qemu-nbd and
qemu-storage-daemon now give access to more or less the same operations
in block drivers as running a system emulator.
In order to address this, introduce a new configure option that enforces
the driver whitelist in all binaries.

configure: Fix endianess test with LTO
If a user is trying to compile QEMU with link-time optimization
enabled by running the configure script like this:
.../configure --extra-cflags="-flto"
then the endianess test is failing since the magic values do not
show up in the intermediate object files there. If the host is
a big endian machine (like s390x), the QEMU binary is then unusable
since the corresponding variable "bigendian" is pre-initialized
with "no".
To fix this issue, we should rather create a full binary and look
for the magic strings there instead.
And we really should not continue the build if the endianess check
failed, to make it clear right from the start that something went
wrong here, thus let's also add some "exit 1" statements here
after emitting the error message.

The standard Sphinx/RTD HTML page footer gives a copyright line
(based on the 'copyright' variable set in conf.py) and a line "Built

disabled via the html_show_sphinx variable, but we leave it enabled).
As a free software project, we'd like to also mention the license
QEMU and its manual are released under.
Add a template footer.html which defines the 'extrafooter' block that
the RtD theme provides for this purpose. The new line of text will
go below the existing copyright and sphinx-acknowledgement lines.
(Unfortunately the RTD footer template does not permit putting it
after the copyright but before the sphinx-acknowledgement.)
We use the templating functionality to make the new text also be a
hyperlink to the about/license.html page of the manual.
Unlike rst files, HTML template files are not reported to our depfile
plugin, so we maintain a manual list in meson.build. New template
files should be rare, so not being able to auto-generate the
dependency info is not too awkward.

The functions vmsa_ttbcr_write and vmsa_ttbcr_raw_write expect
the offset to be for the complete TCR structure, not the offset
to the low 32-bits of a uint64_t. Using offsetoflow32 in this
case breaks big-endian hosts.
For TTBCR2, we do want the high 32-bits of a uint64_t.

We need to walk the PCI bus and check whether the root bus will bypass
