xenParsePCI() does a lot of stuff and, in order to make things cleaner,

- xenParsePCI(): it's a new function that keeps the old name. It's
responsible for the whole per-PCI logic from the old xenParsePCI();
- xenParsePCIList(): it's basically the old xenParsePCI(), but now it
just iterates over the list of PCIs, calling xenParsePCI() per each PCI.
This patch is basically preparing the ground for the future when

For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe. From the differences I only extracted the reply to the new
QMP command and discarded the rest. For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.
In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability. Then removed that one property.
After that I used test/qemucapsfixreplies to fix the reply IDs.

TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy. This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG. The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments. Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here. Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.
