Add ability to retrieve, set file permissions

Add ability to retrieve and set file and permissions.

A demonstration of usefulness would be to add a check to Boost's inspect tool that reports files of known-to-be-not-executable types with the execute permission set.

This looks like something that would be interesting to work on.

Do you already have a design in place or at least an interface you want to expose for this functionality? I find myself often needing this information as well quite often in applications. It should be noted that it should be able to work on directories.

The permissions() function has been added. The functionality is limited, but creating a full permissions and access control abstraction that would cover both Windows and POSIX systems just isn't happening.

If anyone can come up with such an abstraction, with implementation and test cases, I'd be very happy to add it to Boost.Filesystem.

Thanks,
