This patch introduces user configurable parameters to specify RDM
resource and according policies,
Global RDM parameter:
rdm = "strategy=host,policy=strict/relaxed"
Per-device RDM parameter:
pci = [ 'sbdf, rdm_policy=strict/relaxed' ]
Global RDM parameter, "strategy", allows user to specify reserved regions
explicitly, Currently, using 'host' to include all reserved regions reported
on this platform which is good to handle hotplug scenario. In the future
this parameter may be further extended to allow specifying random regions,
e.g. even those belonging to another platform as a preparation for live
migration with passthrough devices. By default this isn't set so we don't
check all rdms. Instead, we just check rdm specific to a given device if
you're assigning this kind of device. Note this option is not recommended
unless you can make sure any conflict does exist.
'strict/relaxed' policy decides how to handle conflict when reserving RDM
regions in pfn space. If conflict exists, 'strict' means an immediate error
so VM can't keep running, while 'relaxed' allows moving forward with a
warning message thrown out.
Default per-device RDM policy is same as default global RDM policy as being
'relaxed'. And the per-device policy would override the global policy like
others.

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?
