Change subject: IMPALA-7979: Enhance decoders to support value-skipping ...................................................................... IMPALA-7979: Enhance decoders to support value-skipping This commit adds value-skipping functionality to the decoders. Value-skipping is useful when we know that we won't need the following N values, so instead of decoding and dropping them, we can just "jump" through them. This feature is a prerequisite for Parquet page skipping (IMPALA-5843). I added backend tests for all the decoders. Backed tests related to bitpacking are moved to the newly created bit-stream-utils-test.
