add getFileSize, which can get the real size of a large file on Windows Avoid using fileSize which maxes out at just 2 gb on Windows. Instead, use hFileSize, which doesn't have a bounded size. Fixes support for files > 2 gb on Windows. Note that the InodeCache code only needs to compare a file size, so it doesn't matter it the file size wraps. So it has been left as-is. This was necessary both to avoid invalidating existing inode caches, and because the code passed FileStatus around and would have become more expensive if it called getFileSize.

explict export lists Eliminated some dead code. In other cases, exported a currently unused function, since it was a logical part of the API. Of course this improves the API documentation. It may also sometimes let ghc optimize code better, since it can know a function is internal to a module. 364 modules still to go, according to git grep -E 'module [A-Za-z.]+ where'

finish fixing removeLink on windows 9cb250f7be21a8f5b15454df4fb67bfd1811e39d got the ones in RawFilePath, but there were others that used the one from unix-compat, which fails at runtime on windows.

use RawFilePath getFileStatus for speed Only done on those calls to getFileStatus that had a RawFilePath, not a FilePath. The others would probably be just as fast if converted to use it with toRawFilePath, but I'm not 100% sure. Note that genInodeCache' uses fromRawFilePath, but that value only gets used on Windows, so on unix the thunk will never be evaluated.
