introducing the disk formats for _RuneLocale and friends. The disk formats do not have (useless) pointers and have 32-bit quantities instead of rune_t and long. (htonl(3) only works with 32-bit quantities, so there's no loss). Bootstrap mklocale(1) when necessary. (Bootstrapping from 4.x would be trivial (verified), but we no longer provide pre-5.3 source upgrades and this is the first commit to actually break it.)
