Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer. The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert. Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer". It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().
The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.

When compiling with -Werror=implicit-fallthrough, gcc complains about
missing fallthrough annotations in this file. Looking at the code,
the fallthrough is indeed wanted here, but instead of adding the
annotations, it can be done more efficiently by simply calculating

Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

The specification says:
0x00 TIME_LOW R: Get current time, then return low-order 32-bits.
0x04 TIME_HIGH R: Return high 32-bits from previous TIME_LOW read.
...
To read the value, the kernel must perform an IO_READ(TIME_LOW),
which returns an unsigned 32-bit value, before an IO_READ(TIME_HIGH),
which returns a signed 32-bit value, corresponding to the higher half
of the full value.
However, we were just returning the current time for both. If the guest
is unlucky enough to read TIME_LOW and TIME_HIGH either side of an
overflow of the lower half, it will see time be in the future, before
jumping backwards on the next read, and Linux currently relies on the
atomicity guaranteed by the spec so is affected by this. Fix this
violation of the spec by caching the correct value for TIME_HIGH
whenever TIME_LOW is read, and returning that value for any TIME_HIGH
read.

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

The current PL031 RTCICR register implementation always clears the
IRQ pending status on a register write, regardless of the value the
guest writes.
To justify that behavior, it references the ARM926EJ-S Development
Chip Reference Manual (DDI0287B) and indicates that said document
states that any write clears the internal IRQ state. It is indeed
true that in section 11.1 this document says:
"The interrupt is cleared by writing any data value to the
interrupt clear register RTCICR".
However, later in section 11.2.2 it contradicts itself by saying:
"Writing 1 to bit 0 of RTCICR clears the RTCINTR flag."
The latter statement matches the PL031 TRM (DDI0224C), which says:
"Writing 1 to bit position 0 clears the corresponding interrupt.
Writing 0 has no effect."
Let's assume that the self-contradictory DDI0287B is in error, and
follow the reference manual for the device itself, by making the
register write-one-to-clear.

Commit 369b41359a broke timer interrupt
reinjection when there is no period change by the guest. In that
case, old_period is 0, which ends up zeroing irq_coalesced (counter of
reinjected interrupts).
The consequence is Windows 7 is unable to synchronize time via NTP.
Easily reproducible by playing a fullscreen video with cirrus and VNC.
Fix by passing s->period when periodic_timer_update is called due to
expiration of the timer. With this change, old_period == 0 only
means that the periodic timer was off.
