On oss-fuzz, we build twice, to put together a build that is portable to
the runner containers. On gitlab ci, this is wasteful and contributes to
timeouts on the build-oss-fuzz job. Avoid building twice on gitlab, at
the remote cost of potentially missing some cases that break oss-fuzz
builds.

The windows cross builds still take way too long in gitlab CI, so need
more targets to be skipped. We don't want to hurt coverage of other
cross builds more though, so we let jobs fine tune with a new env

We take the set of targets that are considered relatively niche or
very old architectures, and skip approx half of them in win32 builds

Commit 584af1f1d9 ("ui/gtk: add a keyboard fifo to the VTE

chr_accept_input() callback function. The code expects a
chr_accept_input() call whenever qemu_chr_be_can_write() bytes
were written. It turns out this is wrong. Some chardev
frontends only call this callback after can_write was 0.
Change the code to send data until the keyboard fifo is empty
or qemu_chr_be_can_write() returns 0.

The logic before was
if not get_option('gnutls').auto() or have_system
Which is equivalent to
if get_option('gnutls').enabled() or get_option('gnutls').disabled() or have_system
This means that the check for gnutls is performed even if gnutls is
disabled, which means that the build system will insist on having
libtasn1 if gnutls is found, even if gnutls support is disabled.
When gnutls is disabled, the check for gnutls shouldn't be performed,
to ensure that further build system logic (like the check for
libtasn1) doesn't make decisions based on the presence of gnutls,
rather than the gnutls option.
After making this change, I can successfully ./configure --disable-gnutls
on my system with gnutls installed, but not libtasn1.

leading \0 character and fixing address details, but didn't use salen

Not taking "salen" into account may result in incorrect "path" being

This reverts commit 0cf8882fd0.
Which this commit, with aarch64 when using efi PCI devices with IO ports
do not work. The reason is that EFI creates I/O port mappings below
0x1000 (in fact, at 0). However Linux, for legacy reasons, does not
support I/O ports <= 0x1000 on PCI, so the I/O assignment created by EFI
is rejected.
EFI creates the mappings primarily for itself, and up until DSM #5
started to be enforced, all PCI resource allocations that existed at
boot were ignored by Linux and recreated from scratch.
Also, the commit in question looks dubious - it seems unlikely that
Linux would fail to create a resource tree. What does
happen is that BARs get moved around, which may cause trouble in some
cases: for instance, Linux had to add special code to the EFI framebuffer
driver to copy with framebuffer BARs being relocated.
DSM #5 has a long history of debate and misinterpretation.

Commit [1] switched PCI hotplug from native to ACPI one by default.
That however breaks hotplug on following CLI that used to work:

-device pcie-root-port,id=pcie-root-port-1,port=0x1,addr=0x1.0x1,bus=pcie.0,chassis=2
where PCI device is hotplugged to pcie-root-port-1 with error on guest side:
ACPI BIOS Error (bug): Could not resolve symbol [^S0B.PCNT], AE_NOT_FOUND (20201113/psargs-330)
ACPI Error: Aborting method \_SB.PCI0.PCNT due to previous error (AE_NOT_FOUND) (20201113/psparse-531)
ACPI Error: Aborting method \_GPE._E01 due to previous error (AE_NOT_FOUND) (20201113/psparse-531)
ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_E01] (20201113/evgpe-515)
cause is that QEMU's ACPI hotplug never supported functions other then 0
and due to bug it was generating notification entries for not described
functions.
Technically there is no reason not to describe cold-plugged bridges
(root ports) on functions other then 0, as they similarly to bridge
on function 0 are unpluggable.
So since we need to describe multifunction devices iterate over
fuctions as well. But describe only cold-plugged bridges[root ports]
on functions other than 0 as well.

Q35 has now ACPI hotplug enabled by default for PCI(e) devices.
As opposed to native PCIe hotplug, guests like Fedora 34
will not assign IO range to pcie-root-ports not supporting
native hotplug, resulting into a regression.
Reproduce by:
qemu-bin -M q35 -device pcie-root-port,id=p1 -monitor stdio
device_add e1000,bus=p1
In the Guest OS the respective pcie-root-port will have the IO range
disabled.
Fix it by setting the "reserve-io" hint capability of the
pcie-root-ports so the firmware will allocate the IO range instead.
