    Fix HTTP-requests for files >= 2GB in size

    An int is 32-bits on all supported platforms, so this has always been broken. The actual file size/request-length sent would depend on fun 2's complement math (a 32GB file was being truncated to 433MB).

    Also fixed some wrong uses of PRIuOFF: off_t is a signed integer, so technically the maximum file size you can request now is 2^63 bytes, which is "big enough".

    Log Message:
    Perform a JS garbage collection for each new request in a reused session

    A reused HTTP session would never (apparently) perform garbage collection.
    The evidence of this was the collection of concurrent user.dat file opens
    that would never close until the HTTP sessions were closed. Hundreds or
    even thousands of open user.dat's have been seen. After this change,
    active web server (webv4 UI) users have not caused these spikes in open user.dat files, at least in my testing.

    If no garbage collection was being performed, then likely a lot of JS
    heap was being needlessly wasted, which could eventually result in a JS
    "out of memory" error. But that's just a theory.

    Investigation is needed into why the js_CommonOperationCallback()'s calls to JS_MaybeGC() were not sufficient to actually perform garbage collection
    in this case.
