Now the init script is called xencommons and, as the name suggests, it
is a common script between xl and xend because it is used to start
xenconsoled, xenstored and xenbackendd and the initialization of these
three daemons has been removed from xend. The global
xen_toolstack=xl/xend variable has been removed. Regarding the
network setup, I made the vif scripts follow the same pattern as the
other scripts in xen-backend: a new script called vif-setup is
executed unconditionally. vif-setup is going to do the right thing
depending on the value of the environmental variable "script" (same
technique used before), defaulting to vif-bridge. In the common
scenario the toolstack doesn't need to set the variable "script"
because vif-bridge is going to be called anyway. There is no global
network script to setup the network bridges with xl, so if you are
using xl without xend, you need to manually configure the bridges
using your distro network setup, or, if you are lazy, you can just add
something like:
/etc/xen/scripts/network-bridge start
to your rc.local.

xl help 'command' should give the help of the 'command',
but current it does not, it just gives a full list of xl
supported commands. This patch fix it.

this patch adds an init script for xl, so that it can be used without
xend installed on the system. In cases in which both toolstacks are
present, only one init script will be run, dependening on the value of
xen_toolstack in /etc/sysconfig/xen_toolstack. Please note that a
correct value of xen_toolstack (either xl or xend), is required now.
The network script and the vif script to be used with xl can be
specified in /etc/sysconfig/xenlightdaemons. Xl sets the vif script
to xl-vif-script by default, that reads /etc/sysconfig/xenlightdaemons
and calls the vif script set there. A port to a debian system should
be straightforward, just replacing /etc/sysconfig with /etc/default
everywhere.

* Provide a way to adjust the flags after logger setup
* Use these to disable progress output from the migration receiver, as

We now require callers to provide a xentoollog_logger* for
libxl_ctx_init, and use that for all our own logging and also for
xc_interface_open.
Corresponding change to xl.c.

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.

When parsing BDFs for pci-attach/detach, check the return of scanf

The parsing of PCI resources has two problems:
1. it assumes devices are 32-bits, whereas the fields in the
"resources" file can have full 64-bit values
2. it only parses the first resource because the format string is
missing a \n
Fix both of these up, which allows my Intel 82574L to work with MSI-X.
However, this should probably be using a PCI access library rather
than rummaging around in /sys/bus/pci...

At present, find_domain() will exit(2) if you specify a domain by
number, but that domain doesn't have a corresponding name. However,
nothing seem to critically depend on common_domname being set, and the
test prevents dom0 or other nameless domains from being named. So
just remove the check.

* Some of the library functions such as fscanf, system, and asprintf
are declared with warn_unused_result (ubuntu server 9.10), causing
compilation errors in libxl.
* When using asprintf, the caller is responsible for freeing the
memory.
* memset takes wrong size argument in one of the places (caught by
a builtin gcc check).
