Since seabios-dir is cloned during build we need to check that it exists before
recursing into it for clean, following the pattern used for qemu-*-dir etc.
Also remove usage of "buildmakevars2shellvars" except when used to poopulate
the environment for qemu-xen-traditional's xen-setup script, which is the only
user.

This solves a long-standing issue in which the pages backing these rings were
pages belonging to dom0 user-space processes. Thus, if the process would die
unexpectedly, Xen would keep posting events to a page now belonging to some
other process.
We update all API-consumers in tree (xenpaging and xen-access).
This is an API/ABI change, so please speak up if it breaks your accumptions.
The patch touches tools, hypervisor x86/hvm bits, and hypervisor x86/mm bits.

Don't use the superfluous shared page, return the event channel directly as
part of the domctl struct, instead.
In-tree consumers (xenpaging, xen-access) updated. This is an ABI/API change,
so please voice any concerns.
Known pending issues:
- pager could die and its ring page could be used by some other process, yet
Xen retains the mapping to it.
- use a saner interface for the paging_load buffer.
This change also affects the x86/mm bits in the hypervisor that process the
mem_event setup domctl.

`xenpvnetboot' supports getting boot images from following locations:
- http://host/path
- https://host/path
- ftp://host/path
- file:///path
- tftp://host/path
- nfs:host:/path
- /path
- /path/file.iso
- /path/filesystem.img
- /dev/sda1
- nfs+iso:host:/path/file.iso
- nfs+iso:host:/path/filesystem.img
To use it, make `xenpvnetboot' as bootloader for PV guest::
bootloader = '/usr/bin/xenpvnetboot'
To get boot images from various locations, set the right bootloader
arguments, e.g.:
bootloarder_args = ['--location=http://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=ftp://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=file:///fedora/x86_64']
bootloarder_args = ['--location=tftp://192.168.0.1/fedora/x86_64']
bootloarder_args = ['--location=/fedora/x86_64']
bootloarder_args = ['--location=/fedora/Fedora-16-x86_64-DVD.iso']
bootloarder_args = ['--location=nfs:192.168.0.1:/fedora/x86_64']
bootloarder_args = ['--location=nfs+iso:192.168.0.1:/fedora/Fedora-16-x86_64-DVD.iso']
You can use `kernel' and `ramdisk' to specify the relative path of
boot kernel and ramdisk. `xenpvnetboot' will join them with the
location to find the boot kernel and ramdisk, e.g.:
kernel = 'images/pxeboot/vmlinuz'
ramdisk = 'images/pxeboot/initrd.img'
bootloarder_args = ['--location=http://192.168.0.1/fedora/x86_64']
kernel = 'fedora/x86_64/images/pxeboot/vmlinuz'
ramdisk = 'fedora/x86_64/images/pxeboot/initrd.img'
bootloarder_args = ['--location=http://192.168.0.1/']
You can also omit the `--location' option and specify the full URL for
`kernel' and `ramdisk' directly, e.g.:
kernel = 'http://192.168.0.1/fedora/x86_64/images/pxeboot/vmlinuz'
ramdisk = 'http://192.168.0.1/fedora/x86_64/images/pxeboot/initrd.img'
If only `--location' is specified and `kernel' and `ramdisk' are not
specified, `xenpvnetboot' will search the following places for boot
images from the location::
('images/xen/vmlinuz', 'images/xen/initrd.img'), # Fedora <= 10 and OL = 5
('boot/i386/vmlinuz-xen', 'boot/i386/initrd-xen'), # openSUSE >= 10.2 and SLES >= 10
('boot/x86_64/vmlinuz-xen', 'boot/x86_64/initrd-xen'), # openSUSE >= 10.2 and SLES >= 10
('current/images/netboot/xen/vmlinuz', 'current/images/netboot/xen/initrd.gz'), # Debian
('images/pxeboot/vmlinuz', 'images/pxeboot/initrd.img'), # Fedora >=10 and OL >= 6
('isolinux/vmlinuz', 'isolinux/initrd.img'), # Fedora >= 10 and OL >= 6
`xenpvnetboot' requires python module `urlgrabber'

If user specifies a libdir it is used, if no libdir is specified
configure checks if $exec_prefix/lib64 is a directory and uses that,
if not lib is used.
$prefix is set by passing the command line option or by default when
calling AC_OUTPUT, but since AC_OUTPUT is called at the end, this is
not really helpful, so we have to set $exec_prefix manually to the
correct value, either $prefix if different than NONE or
$ac_default_prefix.

With changeset 24364:0964341efd65 an event channel based notification of
new responses in the ringbuffer is implemented. This makes the memevent
interface obsolete. Currently a call to p2m_mem_paging_resume() is
triggered twice by xenpaging, once per memevent and once per even
channel. In practice this double call does not lead to issues because
p2m_mem_paging_resume() processes only available events.
xenpaging used the event channel notification since the beginning, but
it was a no-op until changeset mentioned above. This change removes the
unneeded XENMEM_paging_op_resume functionality. Pagers are notified via
an event channel of new requests, and now they are required to notify
the hypervisor about their responses also with an event channel.

Add a parameter for the MMIO hole size when building a HVM domain.
This is useful for specifying a larger than normal MMIO hole to ensure
that no PCIe device's MMIO region overlaps with RAM in a guest's
physical address space. This is needed on certain systems with PCIe
switches with a broken ACS capability. On these systems, if a device
downstream of the switch attempts a DMA to a guest physical address
that overlaps with the MMIO region of another downstream device, then
the switch routes the transfer directly to the device and the read or
write never hits RAM.
