i386/cpu: Consolidate die-id validity in smp context
The field die_id (default as 0) and has_die_id are introduced to X86CPU.
Following the legacy smp check rules, the die_id validity is added to
the same contexts as leagcy smp variables such as hmp_hotpluggable_cpus(),
machine_set_cpu_numa_node(), cpu_slot_to_string() and pc_cpu_pre_plug().

i386: Add die-level cpu topology to x86CPU on PCMachine
The die-level as the first PC-specific cpu topology is added to the leagcy
cpu topology model, which has one die per package implicitly and only the
numbers of sockets/cores/threads are configurable.
In the new model with die-level support, the total number of logical
processors (including offline) on board will be calculated as:
#cpus = #sockets * #dies * #cores * #threads
and considering compatibility, the default value for #dies would be
initialized to one in x86_cpu_initfn() and pc_machine_initfn().

libvhost-user: implement VHOST_USER_PROTOCOL_F_MQ
Existing vhost-user device backends, including vhost-user-scsi and
vhost-user-blk, support multiqueue but libvhost-user currently does not
advertise this.
VHOST_USER_PROTOCOL_F_MQ enables the VHOST_USER_GET_QUEUE_NUM request
needed for a vhost-user master to query the number of queues. For
example, QEMU's vhost-user-net master depends on
VHOST_USER_PROTOCOL_F_MQ for multiqueue.
If you're wondering how any device backend with more than one virtqueue
functions today, it's because device types with a fixed number of
virtqueues do not require querying the number of queues. Therefore the
vhost-user master for vhost-user-input with 2 virtqueues, for example,
doesn't actually depend on VHOST_USER_PROTOCOL_F_MQ. It just enables
virtqueues 0 and 1 without asking.
Let there be multiqueue!

libvhost-user: support many virtqueues
Currently libvhost-user is hardcoded to at most 8 virtqueues. The
device backend should decide the number of virtqueues, not
libvhost-user. This is important for multiqueue device backends where
the guest driver needs an accurate number of virtqueues.
This change breaks libvhost-user and libvhost-user-glib API stability.
There is no stability guarantee yet, so make this change now and update
all in-tree library users.
This patch touches up vhost-user-blk, vhost-user-gpu, vhost-user-input,
vhost-user-scsi, and vhost-user-bridge. If the device has a fixed
number of queues that exact number is used. Otherwise the previous
default of 8 virtqueues is used.
vu_init() and vug_init() can now fail if malloc() returns NULL. I
considered aborting with an error in libvhost-user but it should be safe
to instantiate new vhost-user instances at runtime without risk of
terminating the process. Therefore callers need to handle the vu_init()
failure now.
vhost-user-blk and vhost-user-scsi duplicate virtqueue index checks that
are already performed by libvhost-user. This code would need to be
modified to use max_queues but remove it completely instead since it's
redundant.

virtio-pci: fix missing device properties
Since commit
a4ee4c8baa37154 ("virtio: Helper for registering virtio
device types"), virtio-gpu-pci, virtio-vga, and virtio-crypto-pci lost
some properties: "ioeventfd" and "vectors". This may cause various
issues, such as failing migration or invalid properties.
Since those VirtioPCI devices do not have a base name, their class are
initialized with virtio_pci_generic_base_class_init(). However, if the
VirtioPCIDeviceTypeInfo provided a class_init which sets dc->props,
the properties were overwritten by virtio_pci_generic_class_init().
Instead, introduce an intermediary base-type to register the generic
properties.

Forward memory device class functions either to the actual device or use

virtio-pmem will only be compiled for selected, supported architectures
(that can deal with virtio/pci devices being memory devices). An

bits of the CPSR/XPSR. The architecture specifies that if the
condition bits are 0b1111 this means "always execute" (like 0b1110),
not "never execute"; we were treating it as "never execute". (See
the ConditionHolds() pseudocode in both the A-profile and M-profile
Arm ARM.)
This is a bit of an obscure corner case, because the only legal
way to get to an 0b1111 set of condbits is to do an exception
return which sets the XPSR/CPSR up that way. An IT instruction
which encodes a condition sequence that would include an 0b1111 is
UNPREDICTABLE, and for v8A the CONSTRAINED UNPREDICTABLE choices
for such an IT insn are to NOP, UNDEF, or treat 0b1111 like 0b1110.
Add a comment noting that we take the latter option.

VirtIO-RNG: Update default entropy source to `/dev/urandom`
When QEMU exposes a VirtIO-RNG device to the guest, that device needs a
source of entropy, and that source needs to be "non-blocking", like
`/dev/urandom`. However, currently QEMU defaults to the problematic
`/dev/random`, which on Linux is "blocking" (as in, it waits until
sufficient entropy is available).
Why prefer `/dev/urandom` over `/dev/random`?
---------------------------------------------
The man pages of urandom(4) and random(4) state:
"The /dev/random device is a legacy interface which dates back to a
time where the cryptographic primitives used in the implementation
of /dev/urandom were not widely trusted. It will return random
bytes only within the estimated number of bits of fresh noise in the
entropy pool, blocking if necessary. /dev/random is suitable for
applications that need high quality randomness, and can afford
indeterminate delays."
Further, the "Usage" section of the said man pages state:
"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead,
because it will block until the entropy pool is initialized.
"If a seed file is saved across reboots as recommended below (all
major Linux distributions have done this since 2000 at least), the
output is cryptographically secure against attackers without local
root access as soon as it is reloaded in the boot sequence, and
perfectly adequate for network encryption session keys. Since reads
from /dev/random may block, users will usually want to open it in
nonblocking mode (or perform a read with timeout), and provide some
sort of user notification if the desired entropy is not immediately
available."
And refer to random(7) for a comparison of `/dev/random` and
`/dev/urandom`.
What about other OSes?
----------------------
`/dev/urandom` exists and works on OS-X, FreeBSD, DragonFlyBSD, NetBSD
and OpenBSD, which cover all the non-Linux platforms we explicitly
support, aside from Windows.
On Windows `/dev/random` doesn't work either so we don't regress.
This is actually another argument in favour of using the newly
proposed 'rng-builtin' backend by default, as that will work on
Windows.
- - -
Given the above, change the entropy source for VirtIO-RNG device to
`/dev/urandom`.

We make a few sub-directories recursively, in particular

For goal "all", we do it the nice way: "all" has a prerequisite

recursively. Behaves nicely with -j and -k.
For other goals such as "clean" and "install", the recipe runs make

prepares the ground by renaming the targets we use for "all" to
include the goal for the sub-make. This will permit reusing them for
goals other than "all".
Targets subdir-T for T in $(TARGET_DIRS) run "make all" in T. Rename
to T/all, and declare phony.
Targets romsubdir-R for R in $(ROMS) run "make" in pc-bios/R. Default
goal is "all" for all R. Rename to pc-bios/R/all, and declare phony.
The remainder are renamed just for consistency.
Target subdir-dtc runs "make libbft/libfdt.a" in dtc. Rename to
dtc/all, and declare phony.
Target subdir-capstone runs make $(BUILD_DIR)/capstone/$(LIBCAPSTONE)
in $(SRC_PATH)/capstone. Rename to capstone/all, and declare phony.
Target subdir-slirp runs "make" in $(SRC_PATH)/slirp. Default goal is
all, which builds $(BUILD_DIR)/libslirp.a. Rename to slirp/all, and
declare phony.

console: fix cell overflow
Linux terminal behavior (coming from vt100 I think) is somewhat strange
when it comes to line wraps: When a character is printed to the last
char cell of a line the cursor does NOT jump to the next line but stays
where it is. The line feed happens when the next character is printed.
So the valid range for the cursor position is not 0 .. width-1 but
0 .. width, where x == width represents the state where the line is
full but the cursor didn't jump to the next line yet.
The code for the 'clear from start of line' control sequence (ESC[1K)
fails to handle this corner case correctly and may call
console_clear_xy() with x == width. That will incorrectly clear the
first char cell of the next line, or in case the cursor happens to be on
the last line overflow the cell buffer by one character (three bytes).
Add a check to the loop to fix that.
Didn't spot any other places with the same problem. But it's easy to
miss that corner case, so also allocate one extra cell as precaution, so
in case we have simliar issues lurking elsewhere it at least wouldn't be
a buffer overflow.
v2: squashed in additional checks suggested by Christophe de Dinechin.

hw/i2c/bitbang_i2c: Use in-place rather than malloc'd bitbang_i2c_interface struct
Currently the bitbang_i2c_init() function allocates a
bitbang_i2c_interface struct which it returns. This is unfortunate
because it means that if the function is used from a DeviceState
init method then the memory will be leaked by an "init then delete"
cycle, as used by the qmp/hmp commands that list device properties.
Since three out of four of the uses of this function are in
device init methods, switch the function to do an in-place
initialization of a struct that can be embedded in the
device state struct of the caller.
This fixes LeakSanitizer leak warnings that have appeared in the
patchew configuration (which only tries to run the sanitizers
for the x86_64-softmmu target) now that we use the bitbang-i2c
code in an x86-64 config.

Here's my next pull request for qemu-4.1. I'm not sure if this will
squeak in just before the soft freeze, or just after. I don't think
it really matters - most of this is bugfixes anyway. There's some
cleanups which aren't stictly bugfixes, but which I think are safe
enough improvements to go in the soft freeze. There's no true feature
work.
Unfortunately, I wasn't able to complete a few of my standard battery
of pre-pull tests, due to some failures that appear to also be in
master. I'm hoping that hasn't missed anything important in here.
Highlights are:
* A number of fixe and cleanups for the XIVE implementation
* Cleanups to the XICS interrupt controller to fit better with the new
XIVE code
* Numerous fixes and improvements to TCG handling of ppc vector
instructions
* Remove a number of unnnecessary #ifdef CONFIG_KVM guards
* Fix some errors in the PCI hotplug paths
* Assorted other fixes
