We only had code to understand unit suffixes such as g/m/k (as in
2g/400m/8k) in the configuration parser but not in the command line
option parser. "git pack-objects" worked it around by having a
custom extension to the parse-options API; make it available to
other callers.
The new macro is not called OPT_ULONG() but OPT_HUM_ULONG(), as it
would be bizzarre to have ULONG that understands human friendly
units while INTEGER that does not. It is not named with a shorter
"OPT_HULONG", primarily to avoid having to name a future parallel
for parsing human friendly integer "OPT_HINT".
