Introduce new option 'raw' in file_info functions

[nox]

This option allows the caller not to go through the file server for information about files guaranteed to be local.

This fails under windows platforms. As we removed it from the builds I do not have a log for you at this time.
If you are unable to test this yourself I can supply you with log prints at a later time.

(found something related)
This log below might or might not be old:
Test case: file_SUITE:file_info_basic_directory/1

• CT Error Notification 2014-07-15 00:29:24.970 * file_SUITE:test_directory failed on line 1285 Reason: {badmatch,{ok,{file_info,0,directory,read_write, ...}

Weird, will look into it, though I have no Window box. Please supply logs next time.

@garazdawi is looking into this.
Looks like its a problem on the windows side of things. So you can let it go, we will probably merge it and then fix the problem.

According to the msdn docs, GetFileInformationByHandle can return partial values in the BY_HANDLE_FILE_INFORMATION struct. This seems to be the case for nNumberOfLinks on a number of our test machines.

I've fixed the problem by making sure the struct is initialized to 1 for nNumberOfLinks. See https://github.com/garazdawi/otp/tree/lukas/erts/win32-read_file_info-links for the implementation.

Putting this patch back into nightly builds together with my fix.
