  Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).
