qt_normalizePathSegments()

bool qt_normalizePathSegments	(	QString *	path,
		QDirPrivate::PathNormalizations	flags )

Updates path with redundant directory separators removed, and "."s and ".."s resolved (as far as possible). It returns false if there were ".." segments left over, attempt to go up past the root (only applies to absolute paths), or true otherwise.

This method is shared with QUrl, so it doesn't deal with QDir::separator(), nor does it remove the trailing slash, if any.

When dealing with URLs, we are following the "Remove dot segments" algorithm from https://www.ietf.org/rfc/rfc3986.html#section-5.2.4 URL mode differs from local path mode in these ways: 1) it can set *path to empty ("." becomes "") 2) directory path outputs end in / ("a/.." becomes "a/" instead of "a") 3) a sequence of "//" is treated as multiple path levels ("a/b//.." becomes "a/b/" and "a/b//../.." becomes "a/"), which matches the behavior observed in web browsers.

As a Qt extension, for local URLs we treat multiple slashes as one slash.
