Instead of supplying an extern fn, a simpler native rust fn is supplied and the BlockArguments trait is used to get an extern fn that wraps it.
Previous code was just assigning to an uninitialzed field, so the compiler was dropping it; by changing this to a ptr::write the existing value is no longer dropped.
The old behavior can be replicated by creating a custom closure with a context and function.
Platforms beside OSX and iOS will link to libBlocksRuntime.
It isn't necessary now that travis-ci/apt-package-safelist#2949 is fixed.
When updating to current Rust, there is a warning for a change in the output due to the change in Markdown implementations.
The `gcc` crate has been replaced with `cc`. Additionally, the `gcc:Config` was renamed to `gcc::Build`. This updates both of those. Commit taken from SSheldon/rust-block#8
This also adds A: EncodeArguments and R: Encode bounds on blocks, which is a good idea to require given that the types are being sent to and from Objective-C!
It's also actually nicer to have examples that use the current crate!

I wasn't sure previously whether I wanted to do this in #1, but after seeing that I really want to add
Encodestuff in it, it seemed like a good idea. This PR also adds those bounds and implementations, which fixes theobjc_foundation/blockfeature!(There had already been work on this in a
dev_encodebranch)This also includes the fix for SSheldon/rust-block#8.
