Member predicate NormalizableFilepath::getNormalizedPath

Gets the normalized filepath for this string.

Normalizes .. paths, . paths, and multiple /s as much as possible, but does not normalize case, resolve symlinks, or make relative paths absolute.

The normalized path will be absolute (begin with /) if and only if the original path is.

The normalized path will not have a trailing /.

Only / is treated as a path separator.
