Quite a lot of churn on style, but lots of good work refactoring complicated functions and lots more unit-tests. Thanks mostly to rillig at NetBSD Some interesting entries from ChangeLog o .MAKE.{UID,GID} represent uid and gid running make. o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable checks in InitObjdir. Explicit .OBJDIR target always allows read-only directory. o add more unit tests for META MODE Merge commit '8e11a9b4250be3c3379c45fa820bff78d99d5946' into main Change-Id: I464fd4c013067f0915671c1ccc96d2d8090b2b9c
