// Returns the absolute path to the output directory where log files and other
// test artifacts should be put. The output directory is generally a directory
// named "out" at the project root. This root is assumed to be two levels above
// where the test binary is located; this is because tests execute in a dir
// out/Whatever relative to the project root. This convention is also followed
// in Chromium.
//
// The exception is Android where we use /sdcard/ instead.
//
// If symbolic links occur in the path they will be resolved and the actual
// directory will be returned.
//
// Returns the path WITH a trailing path delimiter. If the project root is not
// found, the current working directory ("./") is returned as a fallback.

//    name - Name of the resource file. If a plain filename (no directory path)

//           hierarchy reflecting that path is assumed to be present.
//    extension - File extension, without the dot, i.e. "bmp" or "yuv".
