The commit that added support for retrieving the APIC IDs from the APs
introduced several usages of cpuid() with NULL parameters, which is not
handled by the underlying implementation. For GCC I expect this results in
writes to the physical address at 0, however when using Clang 19.1.2 the
generated code in smp.o for the whole file is:
tools/firmware/hvmloader/smp.o: file format elf32-i386
Disassembly of section .text:
00000000 <smp_initialise>:
0: 55 pushl %ebp
1: 89 e5 movl %esp, %ebp
3: 53 pushl %ebx
4: 31 c0 xorl %eax, %eax
6: 31 c9 xorl %ecx, %ecx
8: 0f a2 cpuid
Showing the usage of a NULL pointer results in undefined behavior, and
Clang refusing to generate further code after it.
Fix by using a temporary variable in cpuid_count() in place for any NULL
parameter.

A PCI device's irq field is an 8-bit number. A value of 0xff indicates
that the device IRQ is not connected. Additionally, the Linux ACPI code
can convert these 0xff values to IRQ_NOTCONNECTED(0x80000000) because
"0x80000000 is guaranteed to be outside the available range of
interrupts and easy to distinguish from other possible incorrect
values." When the hypercall to assign that IRQ fails, device
passthrough as a whole fails.
Add checking for a valid IRQ and skip the IRQ handling for PCI devices
outside that range. This allows for passthrough of devices without
legacy IRQs.

There are use cases (for example using the PV driver) in Dom0less
setup that require Dom0less DomUs start immediately with Dom0, but
initialize XenStore later after Dom0's successful boot and call to
the init-dom0less application.
An error message can seen from the init-dom0less application on
1:1 direct-mapped domains:
```
Allocating magic pages
memory.c:238:d0v0 mfn 0x39000 doesn't belong to d1
Error on alloc magic pages
```
The "magic page" is a terminology used in the toolstack as reserved
pages for the VM to have access to virtual platform capabilities.
Currently the magic pages for Dom0less DomUs are populated by the
init-dom0less app through populate_physmap(), and populate_physmap()
automatically assumes gfn == mfn for 1:1 direct mapped domains. This
cannot be true for the magic pages that are allocated later from the
init-dom0less application executed in Dom0. For domain using statically
allocated memory but not 1:1 direct-mapped, similar error "failed to
retrieve a reserved page" can be seen as the reserved memory list is
empty at that time.
Since for init-dom0less, the magic page region is only for XenStore.
To solve above issue, this commit allocates the XenStore page for
Dom0less DomUs at the domain construction time. The PFN will be
noted and communicated to the init-dom0less application executed
from Dom0. To keep the XenStore late init protocol, set the connection
status to XENSTORE_RECONNECT.
Since the guest magic region allocation from init-dom0less is for
XenStore, and the XenStore page is now allocated from the hypervisor,
instead of hardcoding the guest magic pages region, use
xc_hvm_param_get() to get the XenStore page PFN. Rename alloc_xs_page()
to get_xs_page() to reflect the changes.
With this change, some existing code is not needed anymore, including:
(1) The definition of the XenStore page offset.
(2) Call to xc_domain_setmaxmem() and xc_clear_domain_page() as we
don't need to set the max mem and clear the page anymore.
(3) Foreign mapping of the XenStore page, setting of XenStore interface
status and HVM_PARAM_STORE_PFN from init-dom0less, as they are set
by the hypervisor.
Take the opportunity to do some coding style improvements when possible.
