ext2fs: Fix old out-of-bounds access.

Overrunning buffer pointed to by (caddr_t)&oip->i_db[0] of 48 bytes by
passing it to a function which accesses it at byte offset 59 using
argument 60UL.

The issue was inherited from an older FFS implementation and
fixed there with by merging UFS2 in r98542. We follow the
FFS fix.

xen: create a new PCI bus override

When running as a Xen PVH Dom0 we need to add custom buses that override
some of the functionality present in the ACPI PCI Bus and the PCI Bus. We
currently override the ACPI PCI Bus, but not the PCI Bus, so add a new
override for the PCI Bus and share the generic functions between them.

conf/files.amd64:
 - Add the new files.

x86/xen/xen_pci_bus.c:
 - Generic file that contains the PCI overrides so they can be used by the
   several PCI specific buses.

xen/xen_pci.h:
 - Prototypes for the generic overried functions.

dev/xen/pci/xen_pci.c:
 - Xen specific override for the PCI bus.

dev/xen/pci/xen_acpi_pci.c:
 - Xen specific override for the ACPI PCI bus.
-u and -U are supposed to affect existing files too.

Fix the watchdog timeout calculation to prevent wrap.  The RPi hardware
can't do a timeout bigger than 15 seconds.  The code wasn't checking for
this and because bitmasking was involved the requested timeout was
basically adjusted modulo-16.  That led to things like a 128 second
timeout actually being a 9 second timeout, which accidentally worked fine
until watchdogd was changed to only pet the dog once every 10 seconds.
In r268924 __fflush was modified so that when write(2) was not successful,
_p and _w are adjusted to account for the partial write (if any).

However, _p and _w should not be unconditionally adjusted and should only
be changed when we actually wrote some bytes, or the accumulated accounting
error will eventually result in a heap buffer overflow.

xen: mask event channels while binding them to a vCPU

Mask the event channel source before trying to bind it to a CPU, this
prevents stray interrupts from firing while assigning them and hitting the
KASSERT in xen_intr_handle_upcall.
