libprefetch: library to prefetch data using tracing.
1: This supports "mem" tracing only.
2: Replay option is modified to use "pread" instead
of readahead.
A simple utility binary "prefetch" is built which links to the library.
The binary allows record, replay and verifying the generated
metadata.
Bug: 362507272
Test: cargo test passes all unit tests.
Verify record, replay and dump options:
./prefetch record --duration 10 --path /data/test/trace-test
./prefetch replay --path /data/test/trace-test
./prefetch dump /data/test/trace-test --format csv
