[29/43] jiffy commit: updated refs/heads/upstream to 446e284

[kx...@apache.org]

Avoid uint64 for 32bit compatibility

Rather than worry about truncation casting from a possibly 64bit value
down to a possibly 32bit size_t we just limit the total bytes per
invocation to 4G using an unsigned integer.

Thanks to @seriyps for the report.

Fixes #61
