2021-05-18tests/docker: add "fetch" sub-commandAlex Bennée1-0/+17

2021-05-18tests/docker: allow "update" to add the current userAlex Bennée1-1/+11

At the same time, convert to pointers, split out parts$N_round_to_int_normal, define a macro for parts_round_to_int using QEMU_GENERIC. This necessarily meant some rearrangement to the rount_to_{,u}int_and_pack routines, so go ahead and convert to parts_round_to_int_normal, which in turn allows cleaning up of the raised exception handling.
