Enumerate Alternative Streams

[Maxhy]

Alternative Streams are supported on Dokan but not their enumeration.
This is originally reported on https://code.google.com/p/dokan/issues/detail?id=290 and https://code.google.com/p/dokan/issues/detail?id=56

We should create a new routine on DokanOperations to pass the request to user FS and handle it properly.

I just added it with a new EnumerateNamedStreams callback on DokanOperations (because of that next Dokan release will be 0.8.0).

mirror.c sample was updated to implement this callback as an example.
You can easily try with mirror.c using the following DOS commands on your volume:

echo test1>>myfile.txt:stream1
echo test2>>myfile.txt:stream2
dir /r
type myfile.txt:stream2

Do not forget to set DOKAN_OPTION_ALT_STREAM on DokanOptions to enable alternative stream on your FS.

Hi.

I'll see the changes, when the next release will be launched!
