Bjørn Erik Pedersen a5d6946387 Return nil in CopyOnWriteFs.MkdirAll when directory exists

Bjørn Erik Pedersen 5e9f8ecaa4 Return os.ErrExist from CopyOnWriteFs.Mkdir/MkdirAll 
Before this commit, `CopyOnWriteFs` would return `syscall.EEXIST` in `Mkdir` and `MkdirAll` when a directory already exists.

The main problem with this is that `os.IsExist` returns `false` for that error on Windows.

These methods now return `os.ErrExist`, which is in line with how the other file systems behave.

Fixes #189

Add an optional Lstater interface 
The interface has one method returning the `FileInfo` and a flag telling if `Lstat` was called or not.

```go
type Lstater interface {
    LstatIfPossible(name string) (os.FileInfo, bool, error)
}
```

`Lstat` is currently only supported by the `OsFs`, but since that `Fs` can be used in others, they will also support it by proxy.

But not always, so hence this optional interface.

The interface is in this commit implemented for:

* BasePathFs
* OsFs
* CopyOnWriteFs
* ReadOnlyFs

Fixes #75

Martin Bertschler 8404a5e8bf don't return error in CopyOnWriteFs OpenFile if it is a not exist error

Tatsushi Demachi 3bf3fe3a71 Fix CopyOnWriteFs Stat to handle *os.PathError 
CopyOnWriteFs Stat function only checks its base file system's file or
directory when its layer file system returns Stat error but if the layer
file system type is OsFs, it returns *os.PathError not syscall.ENOENT so
in this case, the base file system's file or directory is never checked.

This fixes the behavior above by expanding *os.PathError and repacking
the error code if the error type is *os.PathError.
