WalkDir is like Walk but can use ReadDir to read directories,
instead of Readdirnames + Lstat on every entry,
which is usually a significant performance improvement.
(The Lstat can still happen if the walk function calls d.Info.)

Revert CL 137055, which changed Clean("\\somepath\dir\") to return
"\\somepath\dir" on Windows. It's not entirely clear this is correct,
as this path is really "\\server\share\", and as such the trailing
slash may be the path on that share, much like "C:\". In any case, the
change broke existing code, so roll it back for now and rethink for 1.13.

Before this change, if Walk encounters an unreadable directory,
it will call walkFn with this directory twice. Argument err in
the first call is nil, and the second is the permission error.
This change removes the former call and makes Walk call walkFn
with permission error.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.

stripping volume names, emit the original paths so as to make those of

original.

behavioral change that might cause programs to work differently
in Go ≤1.4 vs Go ≥1.5, document what SkipDir on a non-directory
has always meant. If code doesn't want this meaning, it is easy
enough not to return SkipDir on non-directories.

Unless the first element is a Universal Naming Convention (UNC)[0]
path, Join shouldn't create a UNC path on Windows.
For example, Join inadvertently creates a UNC path on Windows when
told to join at least three non-empty path elements, where the first
element is `\` or `/`.
This CL prevents creation of a UNC path prefix when the first path
element isn't a UNC path.
Since this introduces some amount of Windows-specific logic, Join is
moved to a per GOOS implementation.
