Shallow copy of ringbuffer is stored inside the hal. The maximum ringbuffer size is configured by the framework. overrides IBase::debug to: 1. write ringbuffers in memory to flash (wifi tombstones) 2. write wifi tombstones to lshal debug fd in archived format Bug: 70171481 Test: compile, run on device Test: run "lshal debug android.hardware.wifi@1.2::IWifi >> archive.cpio" and compared archived files with originals using diff command Change-Id: I33c30e37f245cfa36e005ba8cdc46e91f6de9237
