Summary: It looks like ASAN with gcc 4.9 works better than 4.8.1. It detected this possibility of heap buffer overflow. This was in our codebase for a year :)

With new compilers I succeeded to run thread sanitizer, too. I'll post output (doesn't look good) and fix some things in separate diffs.

This patch remove the unnecessary Compaction::ReleaseInputs().
Compaction::ReleaseInputs() tries to unref its input_version
and column_family. However, such unref is always done in
~Compaction(), and all current ReleaseInputs() calls are
right before the destructor.

While running cross-functional tests for weak iterators, I

tries to use it after doing a Seek. Fixing it by storing the key locally
so that it is still visible after the Seek.

Summary:
This diff adds BlockBasedTable format_version = 2. New format version brings better compressed block format for these compressions:
1) Zlib -- encode decompressed size in compressed block header
2) BZip2 -- encode decompressed size in compressed block header
3) LZ4 and LZ4HC -- instead of doing memcpy of size_t encode size as varint32. memcpy is very bad because the DB is not portable accross big/little endian machines or even platforms where size_t might be 8 or 4 bytes.
It does not affect format for snappy.
If you write a new database with format_version = 2, it will not be readable by RocksDB versions before 3.10. DB::Open() will return corruption in that case.
Test Plan:
Added a new test in db_test.
I will also run db_bench and verify VSIZE when block_cache == 1GB
