Add devcoredump APIs to hci core so that drivers only have to provide the dump skbs instead of managing the synchronization and timeouts. The devcoredump APIs should be used in the following manner: - hci_devcoredump_init is called to allocate the dump. - hci_devcoredump_append is called to append any skbs with dump data OR hci_devcoredump_append_pattern is called to insert a pattern. - hci_devcoredump_complete is called when all dump packets have been sent OR hci_devcoredump_abort is called to indicate an error and cancel an ongoing dump collection. The high level APIs just prepare some skbs with the appropriate data and queue it for the dump to process. Packets part of the crashdump can be intercepted in the driver in interrupt context and forwarded directly to the devcoredump APIs. Internally, there are 5 states for the dump: idle, active, complete, abort and timeout. A devcoredump will only be in active state after it has been initialized. Once active, it accepts data to be appended, patterns to be inserted (i.e. memset) and a completion event or an abort event to generate a devcoredump. The timeout is initialized at the same time the dump is initialized (defaulting to 10s) and will be cleared either when the timeout occurs or the dump is complete or aborted.
