* Make host functions return TrapReason

This avoids the need to manually store any trap reasons
to the `Runtime` from the host function. This adds the following
benefits:

* It properly composes with the upcoming chain extensions
* Missing to set a trap value is now a compile error

* review: Remove superflous .into()

This fixes the handling of base-path when using `key insert`. Before
the base-path wasn't setup correctly, as done when starting a node. This
resulted in putting the keys into the wrong directory. This pr fixes
this by creating the correct base-path/config dir for the keystore.
Besides that it also removes the insert command from `subkey` as it
doesn't make that much sense. If requested, we could bring it back later.

Fix testing for number of slashing spans.

* add a `current_epoch` to BabeApi

* add current_epoch_start back again

* fix node-runtime

* bump spec version

* rename system Config to system Trait.

command used:
```
find frame/ bin/ test-utils/ utils/ -name *.rs -exec sed -i 's/system::Trait>::/system::Config>::/g' {} \;
find frame/ bin/ test-utils/ utils/ -name *.rs -exec sed -i 's/impl frame_system::Trait for /impl frame_system::Config for /g' {} \;
find frame/ bin/ test-utils/ utils/ -name *.rs -exec sed -i 's/impl system::Trait for /impl system::Config for /g' {} \;
```
plus some manual ones especially for frame-support tests and frame-system

* make construct_runtime handle Pallet and Module

pallets can now be implemented on struct named Pallet or Module, both
definition are valid.
This is because next macro will generate only Pallet placeholder.

* introduce pallet attribute macro

currently just with tests, frame_system and other example hasn't been
upgraded

* allow to print some upgrade helper from decl_storage

* Improved error msg, typo.

`type Module<..> = Pallet<..>` to be used by construct_runtime

* Switch to Value as return type

* Make it possible to calculate the storage as often as you want

So, until now each Substrate based blockchain has calculated the storage
root once, at the end of the block. Now there is Frontier that wants to
calculate some intermediate storage root. However this failed on block
import. The problem with that was the extrinsics root. When building the
block we stored `Default::default()` as extrinsics root, because yeah,
we don't know the extrinsics root before finishing the block. At the end
this extrinsics root was then calculated. But on block import we passed
the already known extrinsics root. This was no problem, as we removed
this value at the end of the block. However when you all the storage
root in between, that changes the storage root between block building
and block import.

This pr changes this behavior. It removes the `ExtrinsicsRoot` storage
entry and also doesn't pass it anymore to `System::initialize`. By doing
it, we remove the difference in the storage and fix the storage root mismatch.

* Update common block in sync after importing blocks of a peer

This updates the sync code to update the common block of a peer, after
we have imported blocks from this peer. This fixes a bug for when we are
connected to one or more nodes that are doing a full sync as our node.
Nodes in full sync will not announce new blocks, as we don't send import
notifications on full sync. The problem as now that we were connected to
some peer that reported some low number as its best and we tried to sync
these blocks. But, as we did not update the common block of this peer,
we would sync these blocks over and over again. Being captured in some
time warp.
The solution to this problem is that we increase the common number as we
import blocks from this peer.
