The current code dumps the memory between arg_start and arg_end,
which contains the argv pointers. This results in the

While QEMU coding style prefers lowercase hexadecimals in constants, the
NVMe subsystem uses the format from the NVMe specifications in comments,
i.e. 'h' suffix instead of '0x' prefix.
Fix this up across the code base.

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.
