* Remove artificial sleep

* Tweak proposer waiting time

* Revert sleep removal

The reason why it was there is because when mine_loop returns, it means an error
happened. In that case, we'd better sleep for a moment before trying again,
because immediately trying would most likely just fail.

* Pass sync oracle to mining

So that it does not mine when major syncing

* Expose build time as a parameter

Instead of hardcode it as previously 100ms.

* Update lock file

* Fix compile

* Support skipping check_inherents for ancient blocks

For PoW, older blocks are secured by the work, and can mostly be considered to
be finalized. Thus we can save both code complexity and validation time by
skipping checking inherents for them.

* Move difficulty fetch function out of loop

To make things faster

* Remove seed from mining

Each engine can use its own Rng source.

“easy” means that there are no major changes required.

* Fix build and bump paste dependency to 0.1.6

* Remove dead code

* Re-add = dependency for futures-preview

* Add missing std features for runtime-io

* Remove git dependencies

as updated versions have been published to crates.io

* try to debug bug

* For sr-io, "std" should imply "no_oom" and "no_panic_handler".

Otherwise, rustc complains (correctly) about duplicate lang items.

* Add missing "runtime-io/std" features

* Fix compilation errors

* Prevent duplicate lang items

Rust does not allow duplicate lang items.  When compiled without the
`std` feature, `sr-io` defines two lang items.  Therefore, `sr-io`
compiled without `feature = "std"` must not be linked with `std`.

However, `pwasm-utils` and `wasmi-validation` both bring in `std` unless
compiled with `default-features = "false"`.  This caused a duplicate
lang item error.  Building both with `default-features = "false"`
prevents this error.  When building with `feature = "std"`, they should
both be built with the `std` feature, so this feature needs to be
explicitly depended on.

* Bump `impl_version`

* Make tests pass

Three tests used 1 less gas than they had previously.

* Don’t try to send a body with a GET request

without adding a Transfer-Encoding or Content-Length header.

So, instead of:
`type ALL_MODULES = (Module1, Module2, Module3)`;
Generate it like this:
`type ALL_MODULES = ((Module1, Module2), Module3,);`

This should make `construct_runtime!` support an "unlimited" number of
modules.

* srml/authority-discovery: Abstract session key type

Previously `srml/authority-discovery` dependet on the `srml/im-online`
session key type directly. With this patch `srml/authority-discovery` is
generic over the session key type it is going to use, as long as it
implements the RuntimeAppPublic trait.

With this patch one can use the `srml/authority-discovery` module
without the `srml/im-online` module.

Next to the above, this patch configures `node/runtime` to use the babe
session keys for the authority discovery module.
