[PATCH 5/6] ref-filter: avoid using `unsigned long` for catch-all data type

[Johannes Schindelin <johannes.schindelin@xxxxxx>]

In its `atom_value` struct, the ref-filter source code wants to store
different values in a field called `ul` (for `unsigned long`), e.g.
timestamps.

However, as we are about to switch the data type of timestamps away from
`unsigned long` (because it may be 32-bit even when `time_t` is 64-bit),
that data type is not large enough.

Simply use `uintmax_t` instead.

Unfortunately, this patch is larger than that because the field's name
was tied to its data type.
