Summary:
CircleCI is stably running. Need to add a gadget.
Also since Circle builds some Windows and Linux, rename Travis and Appveyor builds to their names.

Summary:
As discussed with thatsafunnyname [here](https://discuss.lgtm.com/t/c-c-lang-missing-for-facebook-rocksdb/1079): this configuration enables C/C++ analysis for RocksDB on LGTM.com.
The initial commit will contain a build command (simple `make`) that previously resulted in a build error. The build log will then be available on LGTM.com for you to investigate (if you like). I'll immediately add a second commit to this PR to correct the build command to `make static_lib`, which worked when I tested it earlier today.
If you like you can also enable automatic code review in pull requests. This will alert you to any new code issues before they actually get merged into `master`. Here's an example of how that works for the AMPHTML project: https://github.com/ampproject/amphtml/pull/13060. You can enable it yourself here: https://lgtm.com/projects/g/facebook/rocksdb/ci/.
I'll also add a badge to your README.md in a separate commit — feel free to remove that from this PR if you don't like it.
(Full disclosure: I'm part of the LGTM.com team 🙂. Ping samlanning)

Summary:
From #3417 and after talking to both GitHub and our open source legal team, the recommended approach was to explicitly state the dual-license in the readme.
Changing the license files to accommodate the auto-detection is too much of a pain, would involve editing every code file header.

Summary:
This diff is addressing multiple things with a single goal -- to make RocksDB easier to use:
* Add some functions to Options that make RocksDB easier to tune.
* Add example code for both simple RocksDB and RocksDB with Column Families.
* Rewrite our README.md
Regarding Options, I took a stab at something we talked about for a long time:
* https://www.facebook.com/groups/rocksdb.dev/permalink/563169950448190/
I added functions:
* IncreaseParallelism() -- easy, increases the thread pool and max_background_compactions
* OptimizeLevelStyleCompaction(memtable_memory_budget) -- the easiest way to optimize rocksdb for less stalls with level style compaction. This is very likely not ideal configuration. Feel free to suggest improvements. I used some of Mark's suggestions from here: https://github.com/facebook/rocksdb/issues/54
* OptimizeUniversalStyleCompaction(memtable_memory_budget) -- optimize for universal compaction.
Test Plan: compiled rocksdb. ran examples.
