Title: More newrt file io work

A quick rundown:

- added `file::{readdir, stat, mkdir, rmdir}`
- Added access-constrained versions of `FileStream`; `FileReader` and `FileWriter` respectively
- big rework in `uv::file` .. most actions are by-val-self methods on `FsRequest`; `FileDescriptor` has gone the way of the dinosaurs
- playing nice w/ homing IO (I just copied @ecr's work, hehe), etc
- added `FileInfo` trait, with an impl for `Path`
- wrapper for file-specific actions, with the file path always implied by self's value
- has the means to create `FileReader` & `FileWriter` (this isn't exposed in the top-level free function API)
- has "safe" wrappers for `stat()` that won't throw in the event of non-existence/error (in this case, I mean `is_file` and `exists`)
- actions should fail if done on non-regular-files, as appropriate
- added `DirectoryInfo` trait, with an impl for `Path`
- pretty much ditto above, but for directories
- added `readdir` (!!) to iterate over entries in a dir as a `~[Path]` (this was *brutal* to get working)

...and lots of other stuff. Do your worst!
