We generally assume that loosening permission restrictions can never
fail. We have seen in the past that this assumption is wrong. This has
led to crashes because we generally pass &error_abort when loosening
permissions.
However, a failure in such a case should actually be handled in quite
the opposite way: It is very much not fatal, so qemu may report it, but
still consider the operation successful. The only realistic problem is
that qemu may then retain permissions and thus locks on images it
actually does not require. But again, that is not fatal.
To implement this behavior, we make all functions that change
permissions and that pass &error_abort to the initiating function
(bdrv_check_perm() or bdrv_child_check_perm()) evaluate the
@loosen_restrictions value introduced in the previous patch. If it is
true and an error did occur, we abort the permission update, discard the
error, and instead report success to the caller.
bdrv_child_try_set_perm() itself does not pass &error_abort, but it is
the only public function to change permissions. As such, callers may
pass &error_abort to it, expecting dropping permission restrictions to
never fail.

(see the next patch).

We cannot use bdrv_child_try_set_perm() to give up all restrictions on

BLK_PERM_WRITE. Fix this by making bdrv_mirror_top_child_perm() return
0/BLK_PERM_ALL when we want to give up all permissions, and replacing
bdrv_child_try_set_perm() by bdrv_child_refresh_perms().
The bdrv_child_try_set_perm() before removing the node with
bdrv_replace_node() is then unnecessary. No permissions have changed
since the previous invocation of bdrv_child_try_set_perm().

If a block node uses bdrv_child_try_set_perm() to change the permission
it takes on its child, the result may be very short-lived. If anything
makes the block layer recalculate the permissions internally, it will
invoke the node driver's .bdrv_child_perm() implementation. The
permission/shared permissions masks that returns will then override the
values previously passed to bdrv_child_try_set_perm().
If drivers want a child edge to have specific values for the
permissions/shared permissions mask, it must return them in
.bdrv_child_perm(). Consequentially, there is no need for them to pass
the same values to bdrv_child_try_set_perm() then: It is better to have
a function that invokes .bdrv_child_perm() and calls
bdrv_child_try_set_perm() with the result. This patch adds such a
function under the name of bdrv_child_refresh_perms().

Currently, struct Monitor mixes state that is only relevant for HMP,
state that is only relevant for QMP, and some actually shared state.
In particular, a MonitorQMP field is present in the state of any
monitor, even if it's not a QMP monitor and therefore doesn't use the
state.
As a first step towards a clean separation between QMP and HMP, let
MonitorQMP extend Monitor and create a MonitorQMP object only when the
monitor is actually a QMP monitor.
Some places accessed Monitor.qmp unconditionally, even for HMP monitors.
They can't keep doing this now, so during the conversion, they are
either changed to become conditional on monitor_is_qmp() or to assert()
that they always get a QMP monitor.

Instead of mixing HMP and QMP monitors in the same function, separate
the monitor creation function for both.
While in theory, one could pass both MONITOR_USE_CONTROL and
MONITOR_USE_READLINE before this patch and both flags would do
something, readline support is tightly coupled with HMP: QMP never feeds
its input to readline, and the tab completion function treats the input
as an HMP command. Therefore, this configuration is useless.
After this patch, the QMP path asserts that MONITOR_USE_READLINE is not
set. The HMP path can be used with or without MONITOR_USE_READLINE, like
before.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Now we have some rST format docs in the docs/specs/ manual, we should
actually build and install it.

The docs/specs/index.rst has a couple of minor issues which
we didn't notice because we weren't building the manual:
* the ToC entry for the new PPC XIVE docs points to
a nonexistent file
* the initial comment needs to be marked by '..', not '.',
or it will appear in the output
* the title doesn't match the capitialization used by
the existing interop or devel manuals, and uses
'full-system emulation' rather than the 'system emulation'
that the interop manual title uses
Fix these minor issues before we start trying to build the manual.

The "QEMU compared to other emulators" section of our documentation
hasn't been updated since 2015 (and parts of the text are even older).
We're clearly not very well placed to track the evolution of a
dozen other emulation projects, and an inaccurate or out of date
comparison doesn't serve anybody, so we're best off just removing
the whole documentation section.
If anybody cares strongly about maintaining a comparison page,
it's probably better to do that on the project's wiki where
we can update it more dynamically.

Our user-facing manual currently has a section "translator internals"
which has some high-level information about the design of the
TCG translator. This should really be in our new devel/ manual.
Convert it to RST format and move it there.

The architecture permits FPUs which have only single-precision
support, not double-precision; Cortex-M4 and Cortex-M33 are
both like that. Add the necessary checks on the MVFR0 FPDP
field so that we UNDEF any double-precision instructions on
CPUs like this.
Note that even if FPDP==0 the insns like VMOV-to/from-gpreg,
VLDM/VSTM, VLDR/VSTR which take double precision registers
still exist.

In several places cut and paste errors meant we were using the wrong
type for the 'arg' struct in trans_ functions called by the
decodetree decoder, because we were using the _sp version of the
struct in the _dp function. These were harmless, because the two
structs were identical and so decodetree made them typedefs of the
same underlying structure (and we'd have had a compile error if they
were not harmless), but we should clean them up anyway.

Remove the now unused TCG globals cpu_F0s, cpu_F0d, cpu_F1s, cpu_F1d.
cpu_M0 is still used by the iwmmxt code, and cpu_V0 and
