This patch implements the interleaving between allowlist scan and
no-filter scan. It'll be used to save power when at least one monitor is
registered and at least one pending connection or one device to be
scanned for.

We show the streams separately. They are divided into different sections.
1. "Matched hot streams"
2. "Hot streams in old perf data only"
3. "Hot streams in new perf data only".
For each stream, we report the cycles and hot percent (hits%).
For example,
cycles: 2, hits: 4.08%

Sometimes, a small change in a hot function reducing the cycles of

We have used callchain_node->hit to measure the hot level of one
