Print an error and exit if backend!=0 is used in conjunction with
run_hotplug_scripts. Currently libxl can only execute hotplug scripts
from the toolstack domain (the same domain xl is running from).
Added a description and workaround of this issue on
xl-network-configuration.

This prevents the udev scripts from operating on other tap devices (e.g.
openvpn etc)
Correct the documentation for the "vifname" option which suggested it applied
to HVM tap devices only, which is not the case.
Reported by Michael Young.
Also fix the use of vifname with emulated devices. This is slightly complex.
The current hotplug scripts rely on being able to parse the "tapX.Y" (now
"vifX.Y-emu") name in order to locate the xenstore backend dir relating to the
corresponding vif. This is because we cannot inject our own environment vars
into the tap hotplug events. However this means that if the tap is initially
named with a user specified name (which will not match the expected scheme) we
fail to do anything useful with the device. So now we create the initial tap
device with the standard "vifX.Y-emu" name and the hotplug script will handle
the rename to the desired name. This is also how PV vif devices work -- they
are always created by netback with the name vifX.Y and renamed in the script.
Lastly also move libxl__device_* to a better place in the header, otherwise the
comment about evgen stuff isn't next to the associated functions (noticed jsut
because I was going to add nic_devname near to the setdefault functions)

The `rate` keyword specifies the rate at which the outgoing traffic
will be limited to. The default if this keyword is not specified
is unlimited.
The `rate` keyword supports an optional replenishment interval
parameter for specifying the granularity of credit replenishment.
It determines the frequency at which the vif transmission credit
is replenished. The default interval is 50ms.
For example:
'rate=10Mb/s'
'rate=250KB/s'
'rate=1MB/s@20ms'

I have confirmed that the relevant pages have been transitioned.
What remains is pages which have not yet been moved over:
$ rgrep xenwiki *
tools/libxen/README:http://wiki.xensource.com/xenwiki/XenApi
tools/xenballoon/xenballoond.README:http://wiki.xensource.com/xenwiki/Open_Topics_For_Discussion?action=AttachFile&do=get&target=Memory+Overcommit.pdf
Note that "PythonInXlConfig" never existed in the old wiki and does not exist
in the new. This reference was introduced by 22735:cb94dbe20f97 and was
supposed to have been written prior to the 4.1 release. I have transitioned it
anyway but it's not clear how valuable the message actually is. Perhaps we
should just remove that aspect of it?
