breaking change to std.io API * Merge io.InStream and io.OutStream into io.File * Introduce io.OutStream and io.InStream interfaces - io.File implements both of these * Move mem.IncrementingAllocator to heap.IncrementingAllocator Instead of: ``` %return std.io.stderr.printf("hello\n"); ``` now do: ``` std.debug.warn("hello\n"); ``` To print to stdout, see `io.getStdOut()`. * Rename std.ArrayList.resizeDown to std.ArrayList.shrink. 2017-10-31 16:47:55 +08:00			`const std = @import("std");`
