By combining --linearize with --compress-streams=n, we ensure that no
new compressed data will appear in linearized output, which makes the
output independent of zlib's output. There are other tests to ensure
that linearization works correctly with compression. This commit
involves changing some test outputs and test code as well just
updating test suites.
With QPDF allowing integers to contain 64-bit quantities, this change
is necessary to be able to linearize files whose sizes might be larger
than 10 digits.
