Subject [GitHub] thrift pull request #1462: Add seek function to TCompactInputProtocol

    Add seek function to TCompactInputProtocol

    When Thrift is used in encoding which combine manual and Thrift serialization, such as
Apache Parquet then it is required to be able to position within a file manually.
    As TCompactInputProtocol owns value of transport, it is not possible to access it outside
of TCompactInputProtocol and perform seek operation.
    This patch implements Seek trait for transports which support it.

    This closes #1462

    Added "seek" implementation to transports
    In complex applications, such as Apache Parquet, reading data consist of mixture of manualy
seeking offset and deserailizing object at given offset. As protocol owns transport value,
it is impossible to access transport to call seek() function.
    This patch adds io::Seek trait implementation to thrift's TCompactInputProtocol protocols.
