nvme-ns device is registered to a nvme controller device during the
initialization in nvme_register_namespace() in case that 'bus' property
is given which means it's mapped to a single controller.
This patch introduced a new property 'subsys' just like the controller
device instance did to map a namespace to a NVMe subsystem.
If 'subsys' property is given to the nvme-ns device, it will belong to
the specified subsystem and will be attached to all controllers in that
subsystem by enabling shared namespace capability in NMIC(Namespace
Multi-path I/O and Namespace Capabilities) in Identify Namespace.
Usage:
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
-device nvme,serial=bar,id=nvme1,subsys=subsys0
-device nvme,serial=baz,id=nvme2,subsys=subsys0
-device nvme-ns,id=ns1,drive=<drv>,nsid=1,subsys=subsys0 # Shared
-device nvme-ns,id=ns2,drive=<drv>,nsid=2,bus=nvme2 # Non-shared
In the above example, 'ns1' will be shared to 'nvme0' and 'nvme1' in
the same subsystem. On the other hand, 'ns2' will be attached to the
'nvme2' only as a private namespace in that subsystem.
All the namespace with 'subsys' parameter will attach all controllers in
the subsystem to the namespace by default.

We have nvme-subsys and nvme devices mapped together. To support
multi-controller scheme to this setup, controller identifier(id) has to
be managed. Earlier, cntlid(controller id) used to be always 0 because
we didn't have any subsystem scheme that controller id matters.
This patch introduced 'cntlid' attribute to the nvme controller
instance(NvmeCtrl) and make it allocated by the nvme-subsys device
mapped to the controller. If nvme-subsys is not given to the
controller, then it will always be 0 as it was.
Added 'ctrls' array in the nvme-subsys instance to manage attached
controllers to the subsystem with a limit(32). This patch didn't take
list for the controllers to make it seamless with nvme-ns device.

nvme controller(nvme) can be mapped to a NVMe subsystem(nvme-subsys).
This patch maps a controller to a subsystem by adding a parameter
'subsys' to the nvme device.
To map a controller to a subsystem, we need to put nvme-subsys first and
then maps the subsystem to the controller:
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
If 'subsys' property is not given to the nvme controller, then subsystem
NQN will be created with serial (e.g., 'foo' in above example),
Otherwise, it will be based on subsys id (e.g., 'subsys0' in above
example).

[eblake: fix qcow2_do_open() to use ERRP_GUARD, necessary as the only
caller to pass allow_none=true]
Signed-off-by: Eric Blake <eblake@redhat.com>
Supporting '0x20M' looks odd, particularly since we have a 'B' suffix
that is ambiguous for bytes, as well as a less-frequently-used 'E'
suffix for extremely large exibytes. In practice, people using hex
inputs are specifying values in bytes (and would have written
0x2000000, or possibly relied on default_suffix in the case of
qemu_strtosz_MiB), and the use of scaling suffixes makes the most
sense for inputs in decimal (where the user would write 32M). But
rather than outright dropping support for hex-with-suffix, let's
follow our deprecation policy. Sadly, since qemu_strtosz() does not
have an Err** parameter, and plumbing that in would be a much larger
task, we instead go with just directly emitting the deprecation
warning to stderr.

We have multiple clients of qemu_strtosz (qemu-io, the opts visitor,
the keyval visitor), and it gets annoying that edge-case testing is
impacted by implicit rounding to 53 bits of precision due to parsing
with strtod(). As an example posted by Rich Jones:
$ nbdkit memory $(( 2**63 - 2**30 )) --run \
'build/qemu-io -f raw "$uri" -c "w -P 3 $(( 2**63 - 2**30 - 512 )) 512" '
write failed: Input/output error
because 9223372035781033472 got rounded to 0x7fffffffc0000000 which is
out of bounds.
It is also worth noting that our existing parser, by virtue of using
strtod(), accepts decimal AND hex numbers, even though test-cutils
previously lacked any coverage of the latter until the previous patch.
We do have existing clients that expect a hex parse to work (for
example, iotest 33 using qemu-io -c "write -P 0xa 0x200 0x400"), but
strtod() parses "08" as 8 rather than as an invalid octal number, so
we know there are no clients that depend on octal. Our use of
strtod() also means that "0x1.8k" would actually parse as 1536 (the
fraction is 8/16), rather than 1843 (if the fraction were 8/10); but
as this was not covered in the testsuite, I have no qualms forbidding
hex fractions as invalid, so this patch declares that the use of
fractions is only supported with decimal input, and enhances the
testsuite to document that.
Our previous use of strtod() meant that -1 parsed as a negative; now
that we parse with strtoull(), negative values can wrap around modulo
2^64, so we have to explicitly check whether the user passed in a '-';
and make it consistent to also reject '-0'. This has the minor effect
of treating negative values as EINVAL (with no change to endptr)
rather than ERANGE (with endptr advanced to what was parsed), visible
in the updated iotest output.
We also had no testsuite coverage of "1.1e0k", which happened to parse
under strtod() but is unlikely to occur in practice; as long as we are
making things more robust, it is easy enough to reject the use of
exponents in a strtod parse.
The fix is done by breaking the parse into an integer prefix (no loss
in precision), rejecting negative values (since we can no longer rely
on strtod() to do that), determining if a decimal or hexadecimal parse
was intended (with the new restriction that a fractional hex parse is
not allowed), and where appropriate, using a floating point fractional
parse (where we also scan to reject use of exponents in the fraction).
The bulk of the patch is then updates to the testsuite to match our
new precision, as well as adding new cases we reject (whether they
were rejected or inadvertently accepted before).

When querying image extents for raw image, qemu-nbd reports holes as
zero:
$ qemu-nbd -t -r -f raw empty-6g.raw
$ qemu-img map --output json nbd://localhost
[{ "start": 0, "length": 6442450944, "depth": 0, "zero": true, "data": true, "offset": 0}]
$ qemu-img map --output json empty-6g.raw
[{ "start": 0, "length": 6442450944, "depth": 0, "zero": true, "data": false, "offset": 0}]
Turns out that qemu-img map reports a hole based on BDRV_BLOCK_DATA, but
nbd server reports a hole based on BDRV_BLOCK_ALLOCATED.
The NBD protocol says:
NBD_STATE_HOLE (bit 0): if set, the block represents a hole (and
future writes to that area may cause fragmentation or encounter an
NBD_ENOSPC error); if clear, the block is allocated or the server
could not otherwise determine its status.
qemu-img manual says:
whether the sectors contain actual data or not (boolean field data;
if false, the sectors are either unallocated or stored as
optimized all-zero clusters);
To me, data=false looks compatible with NBD_STATE_HOLE. From user point
of view, getting same results from qemu-nbd and qemu-img is more
important than being more correct about allocation status.
Changing nbd server to report holes using BDRV_BLOCK_DATA makes qemu-nbd
results compatible with qemu-img map:
$ qemu-img map --output json nbd://localhost
[{ "start": 0, "length": 6442450944, "depth": 0, "zero": true, "data": false, "offset": 0}]

We've already broken migration compatibility for all the MPS
boards, so we might as well take advantage of this to simplify
the vmstate for the FPGAIO device by folding the counters
subsection into the main vmstate description.

The AN547 puts the combined UART overflow IRQ at 48, not 47 like the
other images. Make this setting board-specific.

Now we have sufficiently parameterised the code, we can add SSE-300
support by adding a new entry to the armsse_variants[] array.
Note that the main watchdog (unlike the s32k watchdog) in the SSE-300
is a different device from the CMSDK watchdog; we don't have a model
of it so we leave it as a TYPE_UNIMPLEMENTED_DEVICE stub.

Support SSE variants like the SSE-300 with an ARMSSE_CPU_PWRCTRL register
block. Because this block is per-CPU and does not clash with any of the
SSE-200 devices, we handle it with a has_cpu_pwrctrl flag like the
existing has_cachectrl, has_cpusectrl and has_cpuid, rather than
trying to add per-CPU-device support to the devinfo array handling code.

The SSE-300 has four timers of type TYPE_SSE_TIMER; add support in
the code for having these in an ARMSSEDeviceInfo array.

The SSE-300 has a system counter device; add support for SSE
variants having this device.
As with the existing devices like the cache control block, CPUID
block, etc, we don't try to make the MMIO addresses configurable. We
can do that if and when we need to model a future SSE variant which
has the counter in a different location.

The SSE-300 has a slightly different set of shared-per-CPU interrupts,
allow the irq_is_common[] array to be different per SSE variant.
