Colin Cross 098c09334f Remove unnecessary locking in fs ... osFs.acquire and osFs.release are surprisingly expensive, using a combined 345.7s of runtime in an AOSP aosp_cf_x86_64_phone-userdebug build. They are used to ensure we don't use too many simultaneous open files, but many of the functions they are called from don't actually open a file. Remove them from all the stat-based functions (Exists, IsDir, IsSymlink, Lstat, Stat), and from ReadLink. After this change the time spent in acquire and release is effectively zero.
