Removed null-checks since not expecting null. RootedPath's hashCode is called
enough that it's worth optimizing.

Context implementations are currently empty, just doing the plumbing in this
change. Once this is in we can start passing along the ObjectCodecRegistry, which
will allow runtime codec resolution for classes not known at compile time.
We'll also inevitably add some memoization helpers, allowing us to optimize the
serialization process further.

Path and PathFragment have been replaced with String-based implementations. They are pretty similar, but each method is dissimilar enough that I did not feel sharing code was appropriate.
A summary of changes:
PATH
====
* Subsumes LocalPath (deleted, its tests repurposed)
* Use a simple string to back Path
* Path instances are no longer interned; Reference equality will no longer work
* Always normalized (same as before)
* Some operations will now be slower, like instance compares (which were previously just a reference check)
* Multiple identical paths will now consume more memory since they are not interned
PATH FRAGMENT
=============
* Use a simple string to back PathFragment
* No more segment arrays with interned strings
* Always normalized
* Remove isNormalized
* Replace some isNormalizied uses with containsUpLevelReferences() to check if path fragments try to escape their scope
* To check if user input is normalized, supply static methods on PathFragment to validate the string before constructing a PathFragment
* Because PathFragments are always normalized, we have to replace checks for literal "." from PathFragment#getPathString to PathFragment#getSafePathString. The latter returns "." for the empty string.
* The previous implementation supported efficient segment semantics (segment count, iterating over segments). This is now expensive since we do longer have a segment array.
ARTIFACT
========
* Remove Path instance. It is instead dynamically constructed on request. This is necessary to avoid this CL becoming a memory regression.

This makes it clearer that the path fragments in question are relative *to the root*. Confusingly, when the root is absolute, the root relative fragment is also absolute. This makes it a tiny bit clearer that the path fragment may be absolute.

An absolute root accepts any absolute path fragments and simply returns it.
This concept replaces the FileSystem root directory concept.

This class represents a root (such as a package path or an output root) used for file lookups and artifacts. It is meant to be as opaque as possible in order to hide the user's environment from sky keys and sky functions.
Roots are used by RootedPaths and ArtifactRoots.
This CL attempts to make the minimum number of modifications necessary to change RootedPath and ArtifactRoot to use these fields. Deprecated methods and invasive accessors are permitted to minimise the risk of any observable changes.

Blaze had its own class to avoid GC from varargs array creation for the precondition happy path. Guava now (mostly) implements these, making it unnecessary to maintain our own.
This change was almost entirely automated by search-and-replace. A few BUILD files needed fixing up since I removed an export of preconditions from lib:util, which was all done by add_deps. There was one incorrect usage of Preconditions that was caught by error prone (which checks Guava's version of Preconditions) that I had to change manually.

This change rolls forward commit e0d7a540e3c615c628f63fcaaaba0c47fca2cb25 and
commit 8bb4299b28de14eed9d3b57bcaeb9350c81c7db3, and adds a bugfix:
- FileSystem.PathFactory got a new translatePath
method that WindowsFileSystem.PathFactory
overrides to translate absolute Unix paths to
MSYS-relative paths
- Path.getCachedChildPath calls this translatePath
method so the child path is registered with the
correct (translated) parent and under the
correct name (e.g. "C:" instead of say "c")
Below is the rest of the original change
description:
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.

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.
