capstone: Convert Makefile bits to meson bits
There are better ways to do this, e.g. meson cmake subproject,
but that requires cmake 3.7 and some of our CI environments
only provide cmake 3.5.
Nor can we add a meson.build file to capstone/, because the git
submodule would then always report "untracked files". Fixing that
would require creating our own branch on the qemu git mirror, at
which point we could just as easily create a native meson subproject.
Instead, build the library via the main meson.build.
This improves the current state of affairs in that we will re-link
the qemu executables against a changed libcapstone.a, which we wouldn't
do before-hand. In addition, the use of the configuration header file
instead of command-line -DEFINES means that we will rebuild the
capstone objects with changes to meson.build.

s390: guest support for diagnose 0x318
DIAGNOSE 0x318 (diag318) is an s390 instruction that allows the storage
of diagnostic information that is collected by the firmware in the case
of hardware/firmware service events.
QEMU handles the instruction by storing the info in the CPU state. A
subsequent register sync will communicate the data to the hypervisor.
QEMU handles the migration via a VM State Description.
This feature depends on the Extended-Length SCCB (els) feature. If
els is not present, then a warning will be printed and the SCLP bit
that allows the Linux kernel to execute the instruction will not be
set.
Availability of this instruction is determined by byte 134 (aka fac134)
bit 0 of the SCLP Read Info block. This coincidentally expands into the
space used for CPU entries, which means VMs running with the diag318
capability may not be able to read information regarding all CPUs
unless the guest kernel supports an extended-length SCCB.
This feature is not supported in protected virtualization mode.

s390/sclp: add extended-length sccb support for kvm guest
As more features and facilities are added to the Read SCP Info (RSCPI)
response, more space is required to store them. The space used to store
these new features intrudes on the space originally used to store CPU
entries. This means as more features and facilities are added to the
RSCPI response, less space can be used to store CPU entries.
With the Extended-Length SCCB (ELS) facility, a KVM guest can execute
the RSCPI command and determine if the SCCB is large enough to store a
complete reponse. If it is not large enough, then the required length
will be set in the SCCB header.
The caller of the SCLP command is responsible for creating a
large-enough SCCB to store a complete response. Proper checking should
be in place, and the caller should execute the command once-more with
the large-enough SCCB.
This facility also enables an extended SCCB for the Read CPU Info
(RCPUI) command.
When this facility is enabled, the boundary violation response cannot
be a result from the RSCPI, RSCPI Forced, or RCPUI commands.
In order to tolerate kernels that do not yet have full support for this
feature, a "fixed" offset to the start of the CPU Entries within the
Read SCP Info struct is set to allow for the original 248 max entries
when this feature is disabled.
Additionally, this is introduced as a CPU feature to protect the guest
from migrating to a machine that does not support storing an extended
SCCB. This could otherwise hinder the VM from being able to read all
available CPU entries after migration (such as during re-ipl).

ide: cancel pending callbacks on SRST
The SRST implementation did not keep up with the rest of IDE; it is
possible to perform a weak reset on an IDE device to remove the BSY/DRQ
bits, and then issue writes to the control/device registers which can
cause chaos with the state machine.
Fix that by actually performing a real reset.

ide: model HOB correctly
I have been staring at this FIXME for years and I never knew what it
meant. I finally stumbled across it!
When writing to the command registers, the old value is shifted into a
HOB copy of the register and the new value is written into the primary
register. When reading registers, the value retrieved is dependent on
the HOB bit in the CONTROL register.
By setting bit 7 (0x80) in CONTROL, any register read will, if it has
one, yield the HOB value for that register instead.
Our code has a problem: We were using bit 7 of the DEVICE register to
model this. We use bus->cmd roughly as the control register already, as
it stores the value from ide_ctrl_write.
Lastly, all command register writes reset the HOB, so fix that, too.

ide: don't tamper with the device register
In real ISA operation, register writes go out to an entire bus channel
and all listening devices receive the write. The devices do not toggle
the DEV bit based on their own configuration, nor does the HBA
intermediate or tamper with that value.
The reality of the matter is that DEV0/DEV1 accordingly will react to
command register writes based on whether or not the device was selected.
This does not fix a known bug, but it makes the code slightly simpler
and more obvious.

hw/arm/raspi: Remove ignore_memory_transaction_failures on the raspi2
Commit
1c3db49d39 added the raspi3, which uses the same peripherals
than the raspi2 (but with different ARM cores). The raspi3 was
introduced without the ignore_memory_transaction_failures flag.
Almost 2 years later, the machine is usable running U-Boot and
Linux.
In commit
00cbd5bd74 we mapped a lot of unimplemented devices,
commit
d442d95f added thermal block and commit
0e5bbd7406 the
system timer.
As we are happy with the raspi3, let's remove this flag on the
raspi2.

The M-profile definition of the MVFR1 ID register differs slightly

We don't currently implement any M-profile CPUs with fp16 arithmetic,
so this is not yet a visible bug, but correcting the logic now

hw/intc/armv7m_nvic: Only show ID register values for Main Extension CPUs
M-profile CPUs only implement the ID registers as guest-visible if
the CPU implements the Main Extension (all our current CPUs except
the Cortex-M0 do).
Currently we handle this by having the Cortex-M0 leave the ID
register values in the ARMCPU struct as zero, but this conflicts with
our design decision to make QEMU behaviour be keyed off ID register
fields wherever possible.
Explicitly code the ID registers in the NVIC to return 0 if the Main
Extension is not implemented, so we can make the M0 model set the
ARMCPU struct fields to obtain the correct behaviour without those
values becoming guest-visible.

char: fix logging when chardev write fails
The qemu_chr_write_buffer() method sends data to the chardev backend for
writing, and then also writes to the log file. In case the chardev
backend only writes part of the data buffer, we need to make sure we
only log the same subset. qemu_chr_write_buffer() will be invoked again
later to write the rest of the buffer.
In the case the chardev backend returns an error though, no further
attempts to likely to be made to write the data. We must therefore write
the entire buffer to the log immediately.
An example where this is important is with the socket backend. This will
return -1 for all writes if no client is currently connected. We still
wish to write data to the log file when no client is present though.
This used to work because the chardev would return "len" to pretend it
had written all data when no client is connected, but this changed to
return an error in

oss-fuzz: move linker arg to fix coverage-build
The order of the add_project_link_arguments calls impacts which
arguments are placed between --start-group and --end-group.
OSS-Fuzz coverage builds seem to just add these to CFLAGS:
-fprofile-instr-generate -fcoverage-mapping pthread -Wl,--no-as-needed
-Wl,-ldl -Wl,-lm Wno-unused-command-line-argument
The -Wl,-ldl flag that is enough to shift the fork_fuzz.ld linker-script

other calls to make sure the flag is placed correctly.
