AP_Logger: make block logger conform to mavlink expectations of numbering
add support for log time to block logger refactor rotation into backed. Don't start logs when erasing correct log start logic separate read and write points so that requesting log information does not corrupt the current log when starting a new log stop logging first clear the write buffer when starting a new log insert utc time when requesting info for the current log stop logging and request formats again when starting a new log cope with erase happening while we are logging keep pushing out startup messages even when format messages are done don't log to the gcs in the io thread don't start new logs in the io thread don't validate logs while erasing flush logs when stopping logging account for page header when calculating logs sizes don't return data when asked for more data than in the log optimize locking and use separate semaphore to mediate ring buffer access stop logging when the chip is full and send a notification calculate logs sizes correctly even when they wrap read log data correctly even when it wraps add stats support to block logger reset dropped when starting a new log fail logging when the chip is full refactor critical bufferspace checks increase messagewriter budget to 250us and to 300us for FMT
