Change from v5:
- change config name to the proper one, CONFIG_BINDER_TRANSACTION_LATENCY_TRACKING.
- change tracepoint name to more descriptive one, trace_binder_txn_latency_(alloc|info|free)
- enhance some lock protection.

Change from v4:
- split up into patch series.

Change from v3:
- use tracepoints for binder_update_info and print_binder_transaction_ext,
instead of custom registration functions.

Change from v2:
- create transaction latency module to monitor slow transaction.

Change from v1:
- first patchset.
