While invalid values need to be ignored when presenting VPD data to the
user, it would be good to attempt to parse a valid portion of the VPD
instead of marking it invalid as a whole.
Based on a mailing list discussion, the set of accepted characters is
extended to the set of printable ASCII characters.
https://listman.redhat.com/archives/libvir-list/2021-October/msg01043.html
The particular example encountered on real hardware was multi-faceted:
* "N/A" strings present in read-only fields. This would not be a useful
valid value for a field (especially if a unique serial number is
expected), however, it was decided to delegate handling of those kinds
of values to higher-level software;
* "4W/1W PCIeG2x4" - looks like some vendors use even more printable
characters in the ASCII range than we currently allow. Since the
PCI/PCIe VPD specs mention alphanumeric characters without specifying
the full character set, it looks like this is ambiguous for vendors
and they tend to use printable ASCII characters;
* 0xFF bytes present in VPD-W field values. Those bytes do not map to
printable ASCII code points and were probably used by the vendor as
placeholders. Ignoring the whole VPD because of that would be too
strict.

* RV and RW fields must be at the last position in their respective
section (per the conditions in the spec). Therefore, the parser now
stops iterating over fields as soon as it encounters one of those
fields and checks whether the end of the resource has been reached;
* The lack of the RW field is not treated as a parsing error since we
can still extract valid data even though this is a PCI/PCIe VPD spec
violation;
* Individual fields must have a valid length - the parser needs to check
for invalid length values that violate boundary conditions of the
resource.
* A zero-length field may be the last one in the resource, however, the
boundary check is currently too strict to allow that.

It may happen that qemuProcessStop() is called from "qemu-event"
thread. But this thread doesn't have any virIdentity set
(virIdentity being thread local) and therefore it may be unable
to open connection to secondary drivers. It is unable to do so
in split daemon scenario, because in there opening a connection
is coupled with copying current thread identity onto the
connection. Code-wise, virIdentityGetCurrent() returns NULL which
in turn makes virGetConnectGeneric() fail. This problem does not
occur in monolithic daemon scenario, because no identity copying
is done there.
Long story short, inability to open secondary driver connection
can lead to unwanted results. Therefore, do what

This reverts commit 58ba0f6a3d.
Conflict:
* src/qemu/qemu_capabilities.[ch]
Because other new cap flags had been added since the original
commit, reformatting was necessary to follow the "groups of
five" pattern.
* tests.qemucapabilitiesdata/caps_6.2.0.x86_64.xml
This file was added after the original commit that we
are reverting, so had to be manually edited to remove
the two capabilities.

Conflicts:
tests/qemuxml2argvdata/q35-acpi-hotplug-bridge-disable.args
* this file had been renamed from its original, then renamed back,
which understandably confused git. It's being completely removed
here anyway, so the contents don't matter.
