[libvirt] [PATCH 06/32] Convert 'int i' to 'size_t i' in src/{xen, xenapi, xenxs} files



From: "Daniel P. Berrange" <berrange redhat com>

Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

Signed-off-by: Daniel P. Berrange <berrange redhat com>
