Exercise some basic functionality of the new
xc_{get,set}_paging_mempool_size() hypercalls.
This passes on x86, but fails currently on ARM. ARM will be fixed up in
future patches.
This is part of XSA-409 / CVE-2022-33747.

CONFIG_HAS_PCI is not defined for the tools build, and as a result the
vpci harness would never get build. Fix this by building it
unconditionally, there's nothing arch specific in it.

The python unit tests were dropped in Xen 4.12 due to being obsolete, but the
scripts to run the tests were missed. Clean up .gitignore as well.
Also drop the libxenctrl {C,LD}FLAGS adjustments in the Makefile. This logic
isn't used, and isn't appropriate even in principle, as there are tests in
here which don't want to use libxenctrl.

This functionality is going to reside in vpci.c (and the corresponding
vpci.h header), and should be arch-agnostic. The handlers introduced
in this patch setup the basic functionality required in order to trap
accesses to the PCI config space, and allow decoding the address and
finding the corresponding handler that should handle the access
(although no handlers are implemented).
Note that the traps to the PCI IO ports registers (0xcf8/0xcfc) are
setup inside of a x86 HVM file, since that's not shared with other
arches.
A new XEN_X86_EMU_VPCI x86 domain flag is added in order to signal Xen
whether a domain should use the newly introduced vPCI handlers, this
is only enabled for PVH Dom0 at the moment.
A very simple user-space test is also provided, so that the basic
functionality of the vPCI traps can be asserted. This has been proven
quite helpful during development, since the logic to handle partial
accesses or accesses that expand across multiple registers is not
trivial.
The handlers for the registers are added to a linked list that's keep
sorted at all times. Both the read and write handlers support accesses
that expand across multiple emulated registers and contain gaps not
emulated.

Running "make uninstall" does not remove all installed files, a
situation which might cause link related issues if xen is re-installed
in a different location.
In order to make uninstall correctly remove the files it is best
the process should be done recursively by mirroring each "install"
target with an "uninstall" who removes the installed files.
An exception to this rule is uninstalling the files produced by
"qemu-xen-dir-remote" and "qemu-xen-traditional-dir", which are external
to the project. These projects do not implement an "uninstall" target so
the files have to be removed manually.

Add tools/tests/xenstore for a framework to do tests of xenstore.
The aim is to test for correctness and performance.
Add a test program containing some tests meant to be run against any
xenstore implementation (xenstored, oxenstored, xenstore-stubdom).
It is using libxenstore for access to xenstore and supports multiple
tests to be either selected all or individually. All tests are using
/local/domain/<own-domid>/xenstore-test/<pid> as base for doing the
tests. This allows multiple instances of the program to run in
parallel.
