libraries conflict with dependencies bundled in dagger-compiler.jar

[gfx]

dagger-compiler bundles lots of libraries, not as maven dependencies. This causes problems when another annotation processing library uses a newer version of libraries that are used in dagger-compiler.

For example, there is an annotation processor that uses JavaPoet 1.6 feature (e.g. CodeBlock.of()), does not work with Dagger 2.2 because JavaPoet 1.5.1, bundled in dagger-compiler, is loaded.

I think dagger-compiler should not bundle any libraries because users can't control their versions.

Environment

• JDK 1.8.0_77
• Dagger 2.2

Partly a dupe of #228, but JavaPoet is new in Dagger 2.2, and the issue here is that maven-shade-plugin is lacking a relocation rule for com.squareup.

OK, then I think we can just close this as a dupe of #228 and update that to include javapoet as well.
