docs/devel/testing: Dissolve the ci-definitions.rst.inc file
This file was meant for defining the vocabulary for our testing
efforts, but it did not age well: First, the definitions are not
only about the CI part, but also about testing in general, so most
of the information should rather reside in main.rst instead.
Second, some vocabulary has never been really adopted by the QEMU
project, for example we never really use the word "system testing"
since "system" rather means the system emulator binaries in the
QEMU project (and we also don't do any testing with other components
like libvirt and virt-managers here). It also defines that the qtests
are the "functional" tests in QEMU, which is not really up to date
anymore after the "tests/functional" framework has been introduced
a couple of months ago (FWIW, the qtests could rather be seen as a
mix between unit testing and functional testing).
To solve this problem, move the useful parts of this file into
main.rst and directly into ci.rst, and drop the ones (like "system
testing") that we don't really need anymore.

Since we don't run the Avocado jobs in the CI anymore, rename
these variables to QEMU_JOB_FUNCTIONAL and QEMU_CI_FUNCTIONAL.
Also, there was a mismatch between the documentation and the
implementation of QEMU_CI_AVOCADO_TESTING: While the documentation
said that you had to "Set this variable to have the tests using the
Avocado framework run automatically", you indeed needed to set it
to make the pipelines appear in your dashboard - but they were never
run automatically in forks and had to be triggered manually. Let's
improve this now: No need to hide these pipelines from the users
by default anymore (the functional tests should be stable enough
nowadays), and rather allow the users to run the pipelines auto-
matically with this switch now instead, as was documented.

tests/functional: Convert the SMMU test to the functional framework
This test was using cloudinit and a "dnf install" command in the guest
to exercise the NIC with SMMU enabled. Since we don't have the cloudinit
stuff in the functional framework and we should not rely on having access
to external networks (once our ASSETs have been cached), we rather boot
into the initrd first, manually mount the root disk and then use the
check_http_download() function from the functional framework here instead
for testing whether the network works as expected.
Unfortunately, there seems to be a small race when using the files
from Fedora 33: To enter the initrd shell, we have to send a "return"
once. But it does not seem to work if we send it too early. Using a
sleep(0.2) makes it work reliably for me, but to make it even more
unlikely to trigger this situation, let's better limit the Fedora 33
tests to only run with KVM.
Finally, while we're at it, we also add some lines for testing writes
to the hard disk, as we already do it in the test_intel_iommu test.

particular because type array declared with such macro

target/i386: tcg: use cout to commonize add/adc/sub/sbb cases
Use the carry-out vector as the basis to compute AF, CF and OF. The cost
is pretty much the same, because the carry-out is just four boolean
operations, and the code is much smaller because add/adc/sub/sbb now
share most of it.
A similar algorithm to what is used in target/i386/emulate can also be
used for APX, in order to build the result of CCMP/CTEST with a new CC_OP_*.
CCMP needs to place into the flags from either a subtraction or a constant
value; CTEST likewise place into the flags either an AND or a constant
value. The new CC_OP for CCMP and CTEST would store for a successful
predcate:
- in DST and SRC2, the result of the operation;
- in SRC, a carry-out vector for CCMP or zero for CTEST;
If the default flag value is used, DST/SRC/SRC2 can be filled with
constants:
- in DST the negated ZF;
- in SRC's top 2 bits, a value that results in the desired OF and CF;
- in SRC2 a suitable value (any of 0/1/~0/~1) that can be used
instead of DST to compute the desired SF and PF.

target/i386: Reset parked vCPUs together with the online ones
Commit 3f2a05b31ee9 ("target/i386: Reset TSCs of parked vCPUs too on VM
reset") introduced a way to reset TSCs of parked vCPUs during VM reset to
prevent them getting desynchronized with the online vCPUs and therefore
causing the KVM PV clock to lose PVCLOCK_TSC_STABLE_BIT.
The way this was done was by registering a parked vCPU-specific QEMU reset
callback via qemu_register_reset().
However, it turns out that on particularly device-rich VMs QEMU reset
callbacks can take a long time to execute (which isn't surprising,
considering that they involve resetting all of VM devices).
In particular, their total runtime can exceed the 1-second TSC
synchronization window introduced in KVM commit 5d3cb0f6a8e3 ("KVM:
Improve TSC offset matching").
Since the TSCs of online vCPUs are only reset from "synchronize_post_reset"
AccelOps handler (which runs after all qemu_register_reset() handlers) this
essentially makes that fix ineffective on these VMs.
The easiest way to guarantee that these parked vCPUs are reset at the same
time as the online ones (regardless how long it takes for VM devices to
reset) is to piggyback on post-reset vCPU synchronization handler for one
of online vCPUs - as there is no generic post-reset AccelOps handler that
isn't per-vCPU.
The first online vCPU was selected for that since it is easily available
under "first_cpu" define.
This does not create an ordering issue since the order of vCPU TSC resets
does not matter.

target/i386: Fix model number of Zhaoxin YongFeng vCPU template
The model number was mistakenly set to 0x0b (11) in commit ff04bc1ac4.
The correct value is 0x5b. This mistake occurred because the extended
model bits in cpuid[eax=0x1].eax were overlooked, and only the base
model was used.
Using the wrong model number can affect guest behavior. One known issue
is that vPMU (which relies on the model number) may fail to operate
correctly.
This patch corrects the model field by introducing a new vCPU version.

system/main: transfer replay mutex ownership from main thread to main loop thread
On MacOS, UI event loop has to be ran in the main thread of a process.
Because of that restriction, on this platform, qemu main event loop is
ran on another thread [1].
This breaks record/replay feature, which expects thread running qemu_init
to initialize hold this lock, breaking associated functional tests on
MacOS.
Thus, as a generalization, and similar to how BQL is handled, we release
it after init, and reacquire the lock before entering main event loop,
avoiding a special case if a separate thread is used.
