Summary: The patch introduces a helper method in `util/compression.h` called `UncompressData` that dispatches calls to the correct uncompression method based on type, and changes `UncompressBlockContentsForCompressionType` and `Benchmark::Uncompress` in `db_bench` so they are implemented in terms of the new method. This eliminates some code duplication. (`Benchmark::Compress` is also updated to use the previously introduced `CompressData` helper.) In addition, the patch brings the implementation of `Snappy_Uncompress` into sync with the other uncompression methods by making the method compute the buffer size and allocate the buffer itself. Finally, the patch eliminates some potentially risky back-and-forth conversions between various unsigned and signed integer types by exposing the size of the allocated buffer as a `size_t` instead of an `int`.

This directory contains interfaces and implementations that isolate the rest of the package from platform details. Code in the rest of the package includes "port.h" from this directory. "port.h" in turn includes a platform specific "port_<platform>.h" file that provides the platform specific implementation. See port_posix.h for an example of what must be provided in a platform specific header file.
