When switching between AIO contexts we need to me make sure that both
recv_coroutine and send_coroutine are not scheduled to run. Otherwise,
QEMU may crash while attaching the new context with an error like
this one:
aio_co_schedule: Co-routine was already scheduled in 'aio_co_schedule'
To achieve this we need a local implementation of
'qio_channel_readv_all_eof' named 'nbd_read_eof' (a trick already done
by 'nbd/client.c') that allows us to interrupt the operation and to
know when recv_coroutine is yielding.
With this in place, we delegate detaching the AIO context to the
owning context with a BH ('nbd_aio_detach_bh') scheduled using
'aio_wait_bh_oneshot'. This BH signals that we need to quiesce the
channel by setting 'client->quiescing' to 'true', and either waits for
the coroutine to finish using AIO_WAIT_WHILE or, if it's yielding in
'nbd_read_eof', actively enters the coroutine to interrupt it.

The documentation for bdrv_set_aio_context_ignore() states this:
* The caller must own the AioContext lock for the old AioContext of bs, but it
* must not own the AioContext lock for new_context (unless new_context is the
* same as the current context of bs).
As blk_set_aio_context() makes use of this function, this rule also
applies to it.

When we first converted our documentation to Sphinx, we split it into
multiple manuals (system, interop, tools, etc), which are all built
separately. The primary driver for this was wanting to be able to
avoid shipping the 'devel' manual to end-users. However, this is
working against the grain of the way Sphinx wants to be used and
causes some annoyances:
* Cross-references between documents become much harder or
possibly impossible
* There is no single index to the whole documentation
* Within one manual there's no links or table-of-contents info
that lets you easily navigate to the others
* The devel manual doesn't get published on the QEMU website
(it would be nice to able to refer to it there)
Merely hiding our developer documentation from end users seems like
it's not enough benefit for these costs. Combine all the
documentation into a single manual (the same way that the readthedocs
site builds it) and install the whole thing. The previous manual
divisions remain as the new top level sections in the manual.
* The per-manual conf.py files are no longer needed
* The man_pages[] specifications previously in each per-manual
conf.py move to the top level conf.py
* docs/meson.build logic is simplified as we now only need to run
Sphinx once for the HTML and then once for the manpages5B
* The old index.html.in that produced the top-level page with
links to each manual is no longer needed
Unfortunately this means that we now have to build the HTML
documentation into docs/manual in the build tree rather than directly
into docs/; otherwise it is too awkward to ensure we install only the
built manual and not also the dependency info, stamp file, etc. The
manual still ends up in the same place in the final installed
directory, but anybody who was consulting documentation from within
the build tree will have to adjust where they're looking.

SVE predicate operations cannot use the "usual" simd_desc

This abuse broke when SIMD_OPRSZ_BITS was modified in e2e7168a21.

we are manipulating. To be used in future patches.

The next-cube.h file is missing the usual copyright-and-license
header; add it (same as the next-cube.c one).

Add the vmstate for the new NeXTPC devic; this is in theory
a migration compatibility break, but this machine doesn't have
working migration currently anyway.

The fields scsi_irq, scsi_dma, scsi_reset and fd_irq in
NeXTState are all unused, except in commented out
"this should do something like this" code. Remove the
unused fields. As and when the functionality that might
use them is added, we can put in the correct kind of
wiring (which might or might not need to be a qemu_irq,
but which in any case will need to be in the NeXTPC
device, not in NeXTState).

Move the rtc into the NeXTPC struct. Since this is the last
use of the 'backdoor' NextState pointer we can now remove that.
Probably the RTC should be its own device at some point: in hardware
there is a separate MCS1850 RTC chip connected to the Peripheral
Controller via a 1-bit serial interface. That goes beyond the remit
of the current refactoring, though.

Make the next_irq function be GPIO inputs to the NEXT_PC
device, rather than a freestanding set of qemu_irq lines.
This fixes a minor Coverity issue where it correctly points
out the trivial memory leak of the memory allocated in the
call to qemu_allocate_irqs().

All the code which accesses int_status and int_mask is now doing
so via the NeXTPC->NeXTState indirection, so we can move these
fields into the NeXTPC struct where they belong.

Make the next_irq function take a NeXTPC* as its opaque rather than
the M68kCPU*. This will make it simpler to turn the next_irq
function into a gpio input line of the NeXTPC device in the next
commit.
For this to work we have to pass the CPU to the NeXTPC device via a
link property, in the same way we do in q800.c (and for the same
reason).
