Test that data compressed by a compressor that does not obey block sizes is uncompressed properly.

Returns true iff we have hit the end of the input without an error.

Advances to the next nonempty `iovec` and updates related variables.

In a perfect world we'd always have the full buffer to compress when the time came, and we could just call Compress(). Alas, we want to do chunked co

Initialization method to be called if we hit an error while compressing. On hitting an error, call this method before returning the error.

Called at the end of the decompress. We ask the allocator write all blocks to the sink.

We flush only at the end, because the writer wants random access to the blocks and once we hand the block over to the sink, we can't access it anymore

Functions to do unaligned loads and stores in little-endian order.

According to the zlib manual, when you Compress, the destination buffer must have size at least src + .1%*src + 12. This function helps you calculate

Return the number of bytes actually uncompressed so far
