1149: fix(bin) Remove a warning for unreachable code. r=MarkMcCaskey a=Hywan
The `panic!` statement is indeed unreachable for regular usages, but
not for wrong feature configurations. Allowing `unreachable_code` to
avoid a warning.

1133: feat(runtime-c-api) Implement `wasmer_trap` r=Hywan a=Hywan
Idea is to provide an API to get fallible host function by calling `wasmer_trap` to run the Wasmer trapping API.
This is probably the easiest solution to not break the existing API, and not add a lot of complexity in the code.

1147: Update logging to use `log`, add command line flag to toggle it r=MarkMcCaskey a=MarkMcCaskey
This PR:
- ports our logging to the [`log`](https://crates.io/crates/log) crate which is the de-facto standard way to do logging in Rust (it defines a trait which logging backends can implement (we can also implement our own at a later date using these traits)). Another benefit of using the standard logging utilities is that we can now allow users of our libraries to filter and display log messages from Wasmer in a more natural way.
- adds a command line flag to enable/disable logging
- updates the `debug` and `trace` features to pass the correct static toggles to the `log` crate; judging by the `log` documentation these features need to only be set once
- copies and slightly modifies our `fern` configuration from wapm
- updates the makefile so that `make release` compiles out all log statements
- TODO: update CI to not print with color (may not be necessary actually)
