This adds support for multiple namespaces by introducing a new 'nvme-ns'
device model. The nvme device creates a bus named from the device name
('id'). The nvme-ns devices then connect to this and registers
themselves with the nvme device.
This changes how an nvme device is created. Example with two namespaces:
Currently, the device only issues a single block backend request per
NVMe request, but as we move towards supporting metadata (and
discontiguous vector requests supported by OpenChannel 2.0) it will be
required to issue multiple block backend requests per NVMe request.
With this patch the NVMe device is ready for that.

Instead of handling both QSGs and IOVs in multiple places, simply use
QSGs everywhere by assuming that the request does not involve the
controller memory buffer (CMB). If the request is found to involve the
CMB, convert the QSG to an IOV and issue the I/O. The QSG is converted
to an IOV by the dma helpers anyway, so the CMB path is not unfairly
affected by this simplifying change.
As a side-effect, this patch also allows PRPs to be located in the CMB.
The logic ensures that if some of the PRP is in the CMB, all of it must
be located there.

tests:ipmi: Fix IPMI BT tests
The IPMI BT tests had a race condition, if it receive an IPMI command
to enable interrupt, it would write the message to enable interrupts
after it wrote the command response. So the test code could
receive the command response and issue the next command before the
device handled the interrupt enable command, and thus no interrupt.
So send the message to enable interrupt before the command response.
Also add some sleeps to give qemu time to handle responses, there was
no delay before, and it could result in an invalid timeout.

Makefile: Fix in-tree builds when Sphinx is available
In commit 27a296fce9821e we switched the qemu-ga manpage over to
being built from Sphinx. The makefile rules for this were correct
for an out-of-tree build, but break for in-tree builds if Sphinx is
present and we're trying to build the documentation.
Specifically, because Sphinx refuses to build output files into
the same directory as its sources, for an in-tree build we tell
it to build into a subdirectory docs/built, and set up a makefile
variable MANUAL_BUILDDIR indicating where the docs are going.
The makefile rule telling Make how to build qemu-ga.8 correctly
used this variable, but the lines adding qemu-ga.8 to the list
of DOCS to be built and the 'make install' rune did not. The
effect was that for an in-tree build we told Make to build
'docs/interop/qemu-ga.8' but did not provide a specific rule for
doing so, which caused Make to fall back to the old rules.make
rule for building any "%.8" file. Make tried to invoke texi2pod
with a bogus command line, resulting in the error:
GEN docs/interop/qemu-ga.8
No filename or title
make: *** [rules.mak:394: docs/interop/qemu-ga.8]
Fix this by using $(MANUAL_BUILDDIR) when constructing the
list of DOCS files we want to build and also in the source
file name we install for 'make install'.
(Among other things, this broke the Shippable CI builds.)

RISC-V Patches for the 4.2 Soft Freeze, Part 1, v3
This contains quite a few patches that I'd like to target for 4.2.
They're mostly emulation fixes for the sifive_u board, which now much
more closely matches the hardware and can therefor run the same fireware
as what gets loaded onto the board. Additional user-visible
improvements include:
* support for loading initrd files from the command line into Linux, via
/chosen/linux,initrd-{start,end} device tree nodes.
* The conversion of LOG_TRACE to trace events.
* The addition of clock DT nodes for our uart and ethernet.
This also includes some preliminary work for the H extension patches,
but does not include the H extension patches as I haven't had time to
review them yet.
This passes my OE boot test on 32-bit and 64-bit virt machines, as well
as a 64-bit upstream Linux boot on the sifive_u machine. It has been
fixed to actually pass "make check" this time.
Changes since v2 (never made it to the list):
* Sets the sifive_u machine default core count to 2 instead of 5.
Changes since v1 <20190910190513.21160-1-palmer@sifive.com>:
* Sets the sifive_u machine default core count to 5 instead of 1, as

Add a new "hartid-base" property so that hartid number can be
assigned based on the property value.

riscv: hart: Extract hart realize to a separate routine
Currently riscv_harts_realize() creates all harts based on the
same cpu type given in the hart array property. With current
implementation it can only create homogeneous harts. Exact the
hart realize to a separate routine in preparation for supporting
multiple hart arrays.
Note the file header says the RISC-V hart array holds the state
of a heterogeneous array of RISC-V harts, which is not true.
Update the comment to mention homogeneous array of RISC-V harts.

riscv: hw: Remove duplicated "hw/hw.h" inclusion
Commit a27bd6c779ba ("Include hw/qdev-properties.h less") wrongly
added "hw/hw.h" to sifive_prci.c and sifive_test.c.
Another inclusion of "hw/hw.h" was later added via
commit 650d103d3ea9 ("Include hw/hw.h exactly where needed"), that
resulted in duplicated inclusion of "hw/hw.h".

riscv: hmp: Add a command to show virtual memory mappings
This adds 'info mem' command for RISC-V, to show virtual memory
mappings that aids debugging.
Rather than showing every valid PTE, the command compacts the
output by merging all contiguous physical address mappings into
one block and only shows the merged block mapping details.

target/riscv: Create function to test if FP is enabled
Let's create a function that tests if floating point support is
enabled. We can then protect all floating point operations based on if
they are enabled.
This patch so far doesn't change anything, it's just preparing for the
Hypervisor support for floating point operations.
