Summary: So I took a look and I used a pointer to TableBuilder. Changed it to a unique_ptr. I think this should work, but I cannot run valgrind correctly on my local machine to test it.
Test Plan: Run valgrind, but it's not working locally. It says I'm executing an unrecognized instruction.

Summary: In "sst_dump --show_compression_sizes", a reference of CompressionOptions is kept in TableBuilderOptions, which is destroyed later, causing a memory issue.
Test Plan: Run valgrind against SSTDumpToolTest.CompressedSizes and make sure it is fixed

Summary:
sst_dump_tool contains two instances of `fprintf`s where the `format` argument is not
a string literal. This prevents the code from compiling with some compilers/compiler
options because of the potential security risks associated with printing non-literals.

Summary:
Added a new feature to sst_dump_tool.cc to allow a user to see the sizes of the different compression algorithms on an .sst file.
Usage:
./sst_dump --file=<filename> --show_compression_sizes
./sst_dump --file=<filename> --show_compression_sizes --set_block_size=<block_size>
Note: If you do not set a block size, it will default to 16kb
Test Plan: manual test and the write a unit test

Summary: We want to keep Env a think layer for better portability. Less platform dependent codes should be moved out of Env. In this patch, I create a wrapper of file readers and writers, and put rate limiting, write buffering, as well as most perf context instrumentation and random kill out of Env. It will make it easier to maintain multiple Env in the future.
Test Plan: Run all existing unit tests.

Based on feedback from D37083.
Are all of these correct? In some spaces it seems like we're doing SetMaxPossibleForUserKey() although we want the smallest possible internal key for user key.

Summary:
BlockBasedTable pre-fetches the filter and index blocks on Open call.
This is an optimistic optimization targeted for runtime scenario. The
optimization is unnecessary for sst_dump_tool
- Added a provision to disable pre-fetching of index and filter blocks
in BlockBasedTable
- Disabled pre-fetching for the sst_dump tool

The test doesn't pass tough. It seg fault quickly. But I took a look and it doesn't seem to be related to lite version. Likely to be a bug inside RocksDB.
