Offchain-worker APIs stubs (#2615)

Browse Source 
* WiP: HTTP Apis.

* Working on the API.

* Add docs, clean up the API.

* Expose ext_ stuff as well.

* Implement HTTP helpers for offchain sr-io.

* Remove HTTP stuff.

* Revert "Remove HTTP stuff."

This reverts commit 7cca029d6ae93c5849b50edfcc6d2c313ba3e5bf.

* HTTP apis.

* Additional offchain methods.

* Make it compile.

* Implement wasm-ext boundary of offchain methods.

* Add stubs for offchain stuff to prevent panics.

* Fix tests.

* Addres some more issues.

* Introduce typedef, use unsafe from_utf8

* Bump runtime version.

* Introduce error to distinguish deadline and io errors.

* Add local_storage_cas

* Some tests for offchain stuff.

* Address more grumbles.

* Fix tests compilation.

* Fix borked merge.

* Improve docs for expected return values from ext functions.

* Adding new sign/enrypt/decrypt APIs.
