[PATCH 00/41] Add and use error_errno() and warning_errno()

This is a spinoff from my worktree-move topic. This series adds die_errno() companions, error_errno() and warning_errno(), and use them where applicable to reduce the amount of typing (in future). Changes are split by file (which explains the huge number of patches). I leave builtin/apply.c and refs/files-backend.c untouched because they are currently hot zones.
