Use mmap for redacted ranges Previously, a zeroized buffer was allocated for each redacted range. This CL explicitly sets the max read size in FuseDaemon to 128kB, mmap's a zeroized memory region of that size once and reuses this memory for all redacted ranges, Test: adb pull <photo with location data> # location data was redacted Fixes: 140799126 Change-Id: I3f8e8eb747e838967e4603d87bb4ba34e7bf20cb
