target/arm: Advertise Cortex-A53 erratum #843419 fix via REVIDR
The Cortex-A53 r0p4 revision that QEMU emulates is affected by a CatA
erratum #843419 (i.e., the most severe), which requires workarounds in
the toolchain as well as the OS.
Since the emulation is obviously not affected in the same way, we can
indicate this via REVIDR bit #8, which on r0p4 has the meaning that no
workarounds for erratum #843419 are needed.

qapi: Divorce QAPIDoc from QAPIParseError
QAPIDoc stores a reference to QAPIParser just to pass it to
QAPIParseError. The resulting error position depends on the state of
the parser. It happens to be the current comment line. Servicable,
but action at a distance.
The commit before previous moved most uses of QAPIParseError from
QAPIDoc to QAPIParser. There are just three left. Convert them to
QAPISemError. This involves passing info to a few methods. Then drop
the reference to QAPIParser.
The three errors lose the column number. Not really interesting here:
it's the comment line's indentation.

qapi: Reject multiple and empty feature descriptions
The parser recognizes only the first "Features:" line. Any subsequent
ones are treated as ordinary text, as visible in test case
doc-duplicate-features. Recognize "Features:" lines anywhere. A
second one is an error.
A 'Features:' line without any features is useless, but not an error.
Make it an error. This makes detecting a second "Features:" line
easier.

qapi: Rewrite doc comment parser
QAPISchemaParser is a conventional recursive descent parser. Except
QAPISchemaParser.get_doc() delegates most of the doc comment parsing
work to a state machine in QAPIDoc. The state machine doesn't get
tokens like a recursive descent parser, it is fed tokens.
I find this state machine rather opaque and hard to maintain.
Replace it by a conventional parser, all in QAPISchemaParser. Less
code, and (at least in my opinion) easier to understand.

- If the TLB PID changes.

This implements the core timebase state machine, which is the core side
of the time-of-day system in POWER processors. This facility is operated
by control fields in the TFMR register, which also contains status
fields.
The core timebase interacts with the chiptod hardware, primarily to
receive TOD updates, to synchronise timebase with other cores. This
model does not actually update TB values with TOD or updates received
from the chiptod, as timebases are always synchronised. It does step
through the states required to perform the update.
There are several asynchronous state transitions. These are modelled
using using mfTFMR to drive state changes, because it is expected that
firmware poll the register to wait for those states. This is good enough
to test basic firmware behaviour without adding real timers. The values
chosen are arbitrary.

ppc/pnv: Implement the ChipTOD to Core transfer
One of the functions of the ChipTOD is to transfer TOD to the Core

The ChipTOD can be programmed with a target address to send the TOD
value to. The hardware implementation seems to perform this by
sending the TOD value to a SCOM address.
This implementation grabs the core directly and manipulates the
timebase facility state in the core. This is a hack, but it works
enough for now. A better implementation would implement the transfer
to the PnvCore xscom register and drive the timebase state machine
from there.

The ChipTOD (for Time-Of-Day) is a chip pervasive facility in IBM POWER
(powernv) processors that keeps a time of day clock.
In particular for this model are facilities that initialise and start
the time of day clock, and that synchronise that clock to cores on the
chip, and to other chips. In this way, all cores on all chips can
synchronise timebase (TB).
This model implements functionality sufficient to run the skiboot
chiptod synchronisation procedure (with the following core timebase
state machine implementation). It does not modify the TB in the cores
where the real hardware would, because the QEMU ppc timebase
implementation is always synchronised acros all cores.

spapr: Tag pseries-2.1 - 2.11 machines as deprecated
pseries machines before version 2.11 have undergone many changes to
correct issues, mostly regarding migration compatibility. This is
obfuscating the code uselessly and makes maintenance more difficult.
Remove them and only keep the last version of the 2.x series, 2.12,
still in use by old distros.

ppc/spapr: Introduce SPAPR_IRQ_NR_IPIS to refer IRQ range for CPU IPIs.
spapr_irq_init currently uses existing macro SPAPR_XIRQ_BASE to refer to
the range of CPU IPIs during initialization of nr-irqs property.
It is more appropriate to have its own define which can be further
reused as appropriate for correct interpretation.

Since 'softmmu' is quite a loaded term in QEMU, rename the vhyp MMU

vhyp_mmu_ is chosen because the code that manipulates the hash table

hypervisor interface, called vhyp.

target/ppc: Rename registers to match ISA
Several registers have names that don't match the ISA (or convention
with other QEMU PPC registers), making them unintuitive to use with
GDB.
Fortunately most of these registers are obscure and/or have not been
correctly implemented in the gdb server (e.g., DEC, TB, CFAR), so risk
of breaking users should be low.
QEMU should follow the ISA for register name convention (where there is
no established GDB name).

This downloads an Alpine VM image, boots it and downloads and installs
