When handling errp==NULL at object_apply_global_props(), we are
leaving the old error value in `err` after printing a warning.
This makes QEMU crash if two global properties generate warnings:

  $ echo device_add rtl8139 | qemu-system-x86_64 -monitor stdio -global rtl8139.xxx=yyy -global rtl8139.xxx=zzz
  warning: can't apply global rtl8139.xxx=yyy: Property '.xxx' not found
  qemu-system-x86_64: util/error.c:57: error_setv: Assertion `*errp == NULL' failed.
  Aborted (core dumped)

Fix that by making `err` go out of scope immediately after the
warn_report_err() call.

This is the same bug that we fixed in commit 58cfa6c2

Looking at chardev/spice.c code, I realize compilation was broken for
a while with spice-server < 0.12.3. Let's bump required version
to 0.12.5, released May 19 2014, instead of adding more #ifdef.

(this patch combines changes from an early version and some of
Frediano "[PATCH 2/2] spice: Bump required spice-server version to
0.12.6")

According to repology, all the distros that are build target platforms
for QEMU include it:

      RHEL-7: 0.14.0
      Debian (Stretch): 0.12.8
      Debian (Jessie): 0.12.5
      FreeBSD (ports): 0.14.0
      OpenSUSE Leap 15: 0.14.0
      Ubuntu (Xenial): 0.12.6

Note that a previous version of this patch was bumping version to
0.12.6. Unfortunately, Debian Jessie (oldstable) is stuck with spice
server 0.12.5, and QEMU should keep building until after 2y of current
stable (Stretch), which will be around June 17th 2019. Qemu 4.1
should thus be free of bumping to spice-server 0.12.6 during 4.1
development cycle.

Since commit ea9ce893, device_post_init() applies globals directly
from machines and accelerator classes.

There are cases, such as -device scsi-hd,help, where the machine is
setup but there in no accelerator.

Let's skip accelerator globals in this case.

Let's rewrite it properly using ranges. This fixes certain overflows that
are right now possible. E.g.

qemu-system-x86_64 -m 4G,slots=20,maxmem=40G -M pc \
    -object memory-backend-file,id=mem1,share,mem-path=/dev/zero,size=2G
    -device pc-dimm,memdev=mem1,id=dimm1,addr=-0x40000000

Now properly errors out instead of succeeding. (Note that qapi
parsing of huge uint64_t values is broken and fixes are on the way)

Since the last time we sorted things (2988cbea), we've had a
few relapses that were inserted out of order.  Also, we had more
entries that were sorted case-insensitively than not, so let's
document that convention and stick to it.

The Debian Sid repository is not garanteed to be stable, as his
'unstable' name suggest :)

To allow quick testing, Debian maintainers might push packages
various time a day. Sometime package dependencies might break,
which is annoying when using this repository for stable development
(which is not recommended, but Sid provides edge packages we use
for testing).

Debian provides repositories snapshots which are suitable for our
use. Pick a recent date that works. When required, update to newer
releases will be easy.

This fixes current issues with this image:

  $ make docker-image-debian-sid

When the IO size is larger than 2 pages, we move the the pointer one by
one in the pagelist, this is inefficient.

This is a simple benchmark result:

Before:
$ qemu-io -c 'write 0 1G' nvme://0000:00:04.0/1

wrote 1073741824/1073741824 bytes at offset 0
1 GiB, 1 ops; 0:00:02.41 (424.504 MiB/sec and 0.4146 ops/sec)

 $ qemu-io -c 'read 0 1G' nvme://0000:00:04.0/1

read 1073741824/1073741824 bytes at offset 0
1 GiB, 1 ops; 0:00:02.03 (503.055 MiB/sec and 0.4913 ops/sec)

After:
$ qemu-io -c 'write 0 1G' nvme://0000:00:04.0/1

wrote 1073741824/1073741824 bytes at offset 0
1 GiB, 1 ops; 0:00:02.17 (471.517 MiB/sec and 0.4605 ops/sec)

Depending on the interrupt mode of the machine, enable or disable the
XIVE MMIOs.

The 'dual' sPAPR IRQ backend supports both interrupt mode, XIVE
exploitation mode and the legacy compatibility mode (XICS). both modes
are not supported at the same time.

The machine starts with the legacy mode and a new interrupt mode can
then be negotiated by the CAS process. In this case, the new mode is
activated after a reset to take into account the required changes in
the machine. These impact the device tree layout, the interrupt
presenter object and the exposed MMIO regions in the case of XIVE.
