VFS: implement a Windows-specific Path subclass The new subclass WindowsFileSystem.WindowsPath is aware of Windows drives. This change: - introduces a new factory for Path objects so FileSystems can return a custom implementation that instantiates filesystem-specific Paths - implements the WindowsPath subclass of Path that is aware of Windows drives - introduces the bazel.windows_unix_root JVM argument that defines the MSYS root, which defines the absolute Windows path that is the root of all Unix paths that Bazel creates (e.g. "/usr/lib" -> "C:/tools/msys64/usr/lib") except if the path is of the form "/c/foo" which is treated as "C:/foo" - removes all Windows-specific logic from Path PathFragment is still aware of drive letters and it has to remain so because it is unaware of file systems. WindowsPath restricts the allowed path strings to absolute Unix paths where the first segment, if any, is a volume specifier. From now on if Bazel attempts to create a WindowsPath from an absolute Unix path, Bazel will make it relative to WindowsPath.UNIX_ROOT, unless the first component is a single-letter name (e.g. "/c/foo" which is "C:/foo"). Subclassing Path is necessary because a Unix-style absolute path doesn't sufficiently define a full Windows path, as it may be relative to any drive.

{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.
