blktap & parallax reorganize

at the moment blktap directory is a little bit messy: blktap and parallax code are mixed. this patch makes a new directory named parallax under blktap and put parallax code into it. (lets consider that parallax is an "application" or blktap, and we might have more in the future). it also makes some cleanups and little fixes to Makefiles. Andrew, please apply.

this patch is a little bit big, so i gzip it and attach .gz file here (btw, what is the recommend size limit of attachment for this list?)

I'll step back to Xen stable, because of my network probs with Xen unstable. So I configured and compiled Xen 2.0.6, but I came to the following error after starting Xend:

Exception starting xend: 'module' object has no attribute 'VIRQ_DOM_EXC' Traceback (most recent call last):
File "/usr/lib/python/xen/xend/server/SrvDaemon.py", line 302, in run
self.createFactories()
File "/usr/lib/python/xen/xend/server/SrvDaemon.py", line 317, in
createFactories
self.channelF = channel.channelFactory()
File "/usr/lib/python/xen/xend/server/channel.py", line 217, in
channelFactory
inst = ChannelFactory()
File "/usr/lib/python/xen/xend/server/channel.py", line 65, in __init__
self.bind_virq(xen.lowlevel.xc.VIRQ_DOM_EXC)
AttributeError: 'module' object has no attribute 'VIRQ_DOM_EXC'

Can't find anything about it, and Xen did boot actually, with Xen unstable, so Python should be allright.

rm -rf /usr/lib/python/xen

Then reinstall the tools.

Worked for me :-)
