Backport ZFS Support for pygrub to Xen 3.3.1 providing via http://gitco.de

Gitco is providing http://www.gitco.de/repo/src/xen-3.3.1-0.src.rpm for free download. It gives an immediate option to back port Pygrub ZFS support from Xen 3.4-testing mercurial tree. Raw content of CSs 19322,19323 is supposed to be placed into patch files under /usr/src/redhat/SOURCES.
File /usr/src/redhat/SPECS/xen-3.3.1.spec gets updated to process two more patches added to SOURCES. The last step is to run rpmbuild to create RPMS with patches to be installed instead of original ones from http://gitco.de. Details follow bellow:-

# yum -y install transfig texi2html tetex-latex gtk2-devel libaio-devel gnutls-devel
# yum update ecryptfs-utils
