To retain backwards compatibility with some QNetworkReply usage, namely connecting solely to finished-signal and allocating a buffer to read into, but without storing the entire decompressed file in memory until read, we may decompress the file twice. With this patch users can now avoid this double decompression if the amount of buffered data stays below 10 MiB. This means any file smaller than 10 MiB will never need to be decompressed twice to know the size of it. On top of that, if the data is handled as it arrives (e.g. in readyRead) and the buffer is kept below 10 MiB it won't need to decompress twice either. This is active as long as "countDecompressed" is true, though it currently always is in QNetworkAccessManger, with a future goal to make it possible to control with public API. Since it requires the user to potentially adapt their usage of QNetworkReply. In this patch we also stop tracking the amount of unhandled uncompressed bytes (uncompressedBytes) in favor of tracking the total amount of bytes which has been read() by the user of QDecompressHelper (totalBytesRead), since we can more intuitively work out the total amount of unread bytes using this value.
