the Tracepoint's struct. BPF programs can read task information via task
struct pointer. Exposing these pointers explicitly gives BPF programs an
easy and reliable way of using the Tracepoint.

This commit updates function signature of the bpf_perf_event_output and
bpf_perf_event_read helpers to match their implementation. Also updates
their documentation in the header files.
