primop: add readFileType, optimize readDir Allows checking directory entry type of a single file/directory. This was added to optimize the use of `builtins.readDir` on some filesystems and operating systems which cannot detect this information using POSIX's `readdir`. Previously `builtins.readDir` would eagerly use system calls to lookup these filetypes using other interfaces; this change makes these operations lazy in the attribute values for each file with application of `builtins.readFileType`. 2023-01-22 19:45:02 +00:00			`{`
