Pull request description:

  Add fuzzing harnesses for `CAutoFile`, `CBufferedFile`, `LoadExternalBlockFile` and other `FILE*` consumers:
  * Add `FuzzedFileProvider` which provides a `FILE*` interface to `FuzzedDataProvider` using `fopencookie`
  * Add `FuzzedAutoFileProvider` which provides a `CAutoFile` interface to `FuzzedDataProvider`
  * Add serialization/deserialization fuzzing helpers `WriteToStream(…)`/`ReadFromStream(…)`
  * Add fuzzing harness for `CAutoFile` (`streams.h`)
  * Add fuzzing harness for `CBufferedFile` (`streams.h`)
  * Add fuzzing harness for `LoadExternalBlockFile(...)` (`validation.h`)
  * Add fuzzing harness for `CBlockPolicyEstimator::Read` and `CBlockPolicyEstimator::Write` (`policy/fees.h`)

  See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).

  Happy fuzzing :)
