Yoshinori Matsunobu 18ba58a943 Upgrading jemalloc from 3.6.0 to the latest for fbcode+gcc 4.8.1 
Summary:
MyRocks is using jemalloc latest version, not 3.6.0.
Combining multiple versions (3.6.0 in RocksDB and latest in MyRocks)
broke some features -- for example, getting SIGSEGV when heap profiling
was enabled.
This diff switches to use jemalloc latest, if
env variable ROCKSDB_FBCODE_BUILD_WITH_481=1 was set.
My understanding is this env was used by MyRocks only so it would be
safe to change.

Test Plan: building MyRocks then verified jemalloc heap profiling worked

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Build Status

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
