Johannes Schindelin d0a081d1cb pack-objects: widen delta-cache accounting to size_t
These three are a single accounting tuple (the globals tracking
cumulative cached-delta bytes, plus the helper that compares them
against an incoming delta size) and are latently 32-bit on Windows where
`unsigned long` != `size_t`: a pack with many large cached deltas could
wrap silently.

The widening is internally consistent on its own: the additions and
subtractions against delta_cache_size already come from `size_t` sources
(`DELTA_SIZE()` returns `size_t`), and `delta_cacheable()`'s sole caller
in `try_delta()` still passes `unsigned long`, which promotes.

Prerequisite for dropping `try_delta()`'s `cast_size_t_to_ulong()`
shims, which becomes possible once 1create_delta()` and `diff_delta()`
are widened in a later commit.

Note: since `max_delta_cache_size` changes data type to `size_t`, a pair
of new helpers is introduced to parse config values of that type, too.
