Subject: Issue #1319 - Remove stderr_to_file.

This local-debug function is only useful for Android to work around
issues with logspewing and should never be in production builds anyway.

-// Call this if you want a copy of stderr logging sent to a file. This is
-// useful to get around logcat overflow problems on android devices, which use
-// a circular logcat buffer and can intermittently drop messages if there's too
-// much spew.
-//
-// This is intended for local debugging only, DO NOT USE IN PRODUCTION CODE.
-// (This is ifndef RELEASE_OR_BETA to catch uses of it that accidentally get
-// checked in). Using this will also prevent the profiler from getting a copy of
-// the stderr messages which it uses for various visualization features.
-//
-// This function can be called from any thread, but if it is called multiple
-// times all invocations must be on the same thread. Invocations after the
-// first one are ignored, so you can safely put it inside a loop, for example.
-// Once this is called there is no way to turn it off; all stderr output from
-// that point forward will go to the file. Note that the output is subject to
-// buffering so make sure you have enough output to flush the messages you care
-// about before you terminate the process.
-//
-// The file passed in should be writable, so on Android devices a path like
-// "/data/local/tmp/blah" is a good one to use as it is world-writable and will
-// work even in B2G child processes which have reduced privileges. Note that the
-// actual file created will have the PID appended to the path you pass in, so
-// that on B2G the output from each process goes to a separate file.
