Fix gzip byte counts with 32-bit integers
If zlib is without our local change in lib/libz/zlib.h r1.7, then
s->z_stream.total_in and s->z_stream.total_out might overflow on
architectures where uLong has 32 bits. After overflow, the total
would be 4G below the correct total.
Calculate our own 64-bit totals. When decompressing, take
(uLong)s->z_stream.total_in as a total modulo ULONG_MAX + 1.
