You can now use GetStatData to get all of the stat data for a file (its timestamps, size, read-only state, and type (file or directory)) in a single file-system request. Depending on the platform, this can be much more efficient than making multiple requests.
This change also adds alternate directory iteration functions (IterateDirectoryStat and IterateDirectoryStatRecursive) for when you need the stat data along with the files/directories on disk. For platforms that provide this stat data as part of the low-level directory iteration (such as Windows), this can yield much better performance than making two separate file-system requests. Platforms that do not provide this information as part of the directory iteration will just perform a stat request while iterating.

Remove async read/write path for now - the server never supported really supported full duplex so the extra complexity is probably not worth it. Need to rethink how async path should work.
