Summary:
Change the license of the source code from BSD + PATENTS to MIT.
Change `checkCopyright` to reflect the new license and learn some new file
types.
Generated with:
```
git grep BSD | xargs -n 1 ./scripts/checkCopyright -i

Summary: To simplify things, have a separate set of simple trace->event elements. Currently this is not used for reporting, in preparation for another diff.

For now: just moving this list behind an abstract type.
Next: changing the internal representation.

fbshipit-source-id: 5b959b0
Summary:
`IList.map_changed` relies on `take_append`.
The existing code was a `take_rev_append` instead.
Fixed it.
Tests are still passing, we might want to look at callsites and consider a `map_changed_unordered`.

fbshipit-source-id: 05a1b38
Summary:
Preparing for the future change, we won't see instructions as lists but as an abstract type.
This change may be a very minor perf regression: does a few more (but bounded by a constant) instructions traversals only for the nodes involving a Printf-like function call, only for the PrintfArgs checker...

Summary:
We never really need the list of nodes/succs/preds, we only need to fold over them.
This will reduce garbage for computed lists like in the Exceptional CFG or the OneInstrPerNode CFG.

Summary: In preparation to change the underlying module structure so as to allow three-point traces (call-site, intermediate call-site and endpoint), rename modules to better reflect function plus use records vs pairs of pairs :P

fbshipit-source-id: ed3e4ac
Summary:
There can be multiple reports per line, especially when calling in a method which has itself multiple reports.
When reporting at the callsite, report only the issue with the highest severity (picked manually per type of event).
Deadlocks are not de-duplicated, as they are relatively rare and the info in mupltiple reports may be important.

The main motivation is preparing for a future change.
This also reduces lifetime of potential garbage.

Rely on the underlying CFG preds:
- perf: no need to append lists
- correctness: the underlying CFG may be removing duplicates

fbshipit-source-id: bc14a2c
Summary:
Moving away from C++ include-based models means that we cannot reliably detect
anymore whether a file includes <iostream> or not. In order not to be too
spammy, let's always assume standard streams are initialized for now when the
include models are off.
Recent versions of libstdc++ make these models redundant so there is hope that in a
bright future the analysis of std streams initialisation will work correctly without infer
having to have its own models anyway.

Summary:
The reported location was always the start of the enclosing procedure, which is wrong in many ways.
A nice side-effect is that some code can then be eliminated and Ondemand.analyze used, avoiding getting the procdescs in the process.

Summary: The type of array element is not preserved correctly in the translation from SIL to HIL. When array element is passed by a reference, i.e. `f(&(array[0]))`, the type of array element gets the type of a pointer of array element.
