Upgrade to ICU 59.1

Also regenerated all patches using make icu.genpatch (hence the .1
suffix that indicates the path level) as some hunks did not apply anyway
and all now have the correct offset. Using genpatch may have the future
benefit to yield smaller diffs between different versions of patches.
Also prefixed all patch names with icu4c- for a cleaner listing.
New patches introduced are prefixed with icu4c-59-...
