* Emulate gas price calculation

* Make clippy happy

* Use Saturating impl for emulating gas price calculation offchain

* Fmt

* Add offchain gas_price test

* Make clippy happy

* Support quickcheck tests

Quickcheck runs multiple tests in one thread, whereas the
testing environment expects one test per thread, since the
offchain env is `thread_local!`.

This commit adds the possibility to have each test run
with an explicitly uninitialized env.

* Introduce ink-fuzz feature

Computationally expensive fuzzing tests should have
to be run explicitly with `--features ink-fuzz`.

These tests must be marked `#[cfg(feature = "ink-fuzz")]`.

* Add quickcheck property testing for HashMap

* Make ink-fuzz imply std feature

* Support quickcheck tests

By adding the ability to reset the offchain environment explicitly.
