Windows, JNI: move around sources

Move the Java JNI sources to a separate package:
c.g.devtools.build.lib.windows.jni and
c.g.devtools.build.lib.windows.runfiles.
Make the native method declarations private,
create public wrapper methods for them that ensure
that the JNI library is loaded.

Split the C++ JNI source processes.cc into two
parts (processes-jni.cc and file-jni.cc), extract
common functionality to jni-util.{h,cc}.

This change preparse the code for Android rule
support on Windows, specifically it lets the
Android BusyBox use the file JNI library so it can
create junctions on Windows to work around long
path issues when calling external tools.

Bazel (Beta)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
