Move bin_dir/genfiles_dir to RuleContext

This is so that the repository name can be included in the root.

To avoid breaking Bazel's CI which tests the HEAD code against the latest
release, none of the Skylark rules in Bazel can be updated to use
ctx.{bin,genfiles}_dir yet, we will have to wait for the 0.3.2 release to
actually update the call sites.  However, this change is to effectively
deprecate ctx.configuration.{bin,genfiles}_dir: it undocuments them and I will
announce the change on the list.

RELNOTES[INC]: bin_dir and genfiles_dir are now properties of ctx, not
configuration. That is, to access the bin or genfiles directory from a
Skylark rule, use ctx.bin_dir or ctx.genfiles_dir (not
ctx.configuration.{bin,genfiles}_dir).  At the moment, you can access
{bin,genfiles}_dir from either, but the ctx.configuration version will
stop working in a future release.

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.
