* path = absolute path
* buf = buffer of at least max(2, strlen(path)+1) bytes
* It is okay if buf == path, but they should not overlap otherwise.
* It is okay if dst == src, but they should not overlap otherwise.
*
* Performs the following normalizations on path, storing the result in buf:
* - Removes trailing slashes.
* - Removes empty components.
* Performs the following normalizations on src, storing the result in dst:
* - Ensures that components are separated by '/' (Windows only)
* - Squashes sequences of '/'.
* - Removes "." components.
* - Removes ".." components, and the components the precede them.
* "" and paths that contain only slashes are normalized to "/".
* Returns the length of the output.
* Returns failure (non-zero) if a ".." component appears as first path
* component anytime during the normalization. Otherwise, returns success (0).
*
* Note that this function is purely textual. It does not follow symlinks,
* verify the existence of the path, or make any system calls.
