Alejandro Vallejo 4af349a404 tools: Make some callers of xc_domain_getinfo() use xc_domain_getinfolist()
xc_domain_getinfo() is slow and prone to races because N hypercalls are
needed to find information about N domains. xc_domain_getinfolist() finds
the same information in a single hypercall as long as a big enough buffer
is provided. Plus, xc_domain_getinfo() is disappearing on a future patch
so migrate the callers interested in more than 1 domain to the the *list()
version.
