Adds the general-purpose -o flag to address ninja-build#746, with options for verbosity (ninja-build#480) and control sequence stripping (ninja-build#581, ninja-build#672, ninja-build#916). Also provides the ability to enable both verbose and raw output as a workaround for ninja-build#1214 without changing the existing verbose behavior. -o verbose show all command lines while building -o quiet hide command lines and outputs while building -o raw never strip control sequences from output -o strip always strip control sequences from output -o color strip most control sequences from output, but retain color codes This patch does not affect Ninja's defaults of normal verbosity and smart terminal detection for escape sequence stripping. "-o color" is particularly useful for utilities like `head` and `less -R` that interpret color codes from stdin and pass this colored output to stdout. Any valid ANSI color code, of the form: `'ESC' '[' [ colors ] 'm'` where `colors` is a semicolon-delimited list of optional integers: `[ n ] [ ';' colors ]` is retained in its entirety when using "-o color" (any other CSI escape sequences besides ANSI color codes are still stripped for non-smart terminals).
