Summary:
Given two analysis results, it's now possible to compare them with the following command:
infer --diff --report-current reportA.json --report-previous reportB.json --file-renamings file_renamings.json
this command will then generate 3 files in `infer-out/differential/{introduced, fixed, preexisting}.json`, whose meaning is the following:
- `introduced.json` has all issues in `current` that are not in `previous`
- `fixed.json` has all issues in `previous` that are not in `current`
- `preexisting.json` has all issues that are in both `current` and `previous`
The json files generated can then be used to categorise results coming from incremental analyses of a codebase.

Summary:
In order to be able to report races like
```
synchronized write() {
this.f = ...
}
read() {
return this.f;
}
```
, we need to track writes that happen inside of synchronization as well as writes that happen outside of synchronization.
This diff takes a step toward making that possible by defining an "AccessDomain" mapping a precondition for the safety of a write ( {Safe, SafeIf i, Unsafe} =~ {true, owned(i), false} ) to a set of writes that are safe if the precondition will hold.
We're not actually tracking safe writes yet, but this domain will make it easy to do so.
This also lets us kill the conditional writes/unconditional writes combo, which was a bit clumsy

* Makes running Android example simpler - APG 2.2.0 automatically downloads dependencies so long as the user has previously accepted the Android SDK License.
* APG 2.2.0 requires Gradle 2.14 or newer, so updated to latest.
* Added `buildOptions.abortOnError false` so the build doesn't report any lint issues - the sample is designed to show Infer working, not Android lint.

Summary:
This is helpful to make sure tests are up to date wrt the models.
Also made the Java deps depend on the models.jar instead of the model sources
as that's what the tests will be using. In particular, updating the sources of
the models will not update the results of a test unless someone rebuilds
models.jar, so rerunning the tests when the models haven't been rebuilt is
useless.

Summary:
With the ondemand analysis framework, the concept of timestamp was only being use to check if a procedure has already been analyzed. There was already a concept of "active" procedure for the procedure that were already being analyzed. This revision removes the concept of timestamp and merge it with the concept of analysis status.
This can be simplified further once the analysis always goes through `Ondemand.analyze`.
