* Improve VM executor stack size estimation rules

* typo: docs add "(Debug build)" comment

* Fix an off by one typo and set minimal stack size

This avoids the case if `depth_threshold == max_depth`. Usually setting stack size to zero will just rebound it to
platform minimal stack size, but we set it here just in case.

* Bump master to 1.12

* Bump crates to 1.12

* Bump mac installer version to 1.12

* Update Gitlab scripts

* Update wasmi to 0.2

New wasmi supports 32bit platforms and no longer requires a special feature to build for such platforms.

* Update pwasm-utils to 0.1.5

* Return error if RLP size of transaction exceeds the limit

* Review comments fixed

* RLP check moved to verifier, corresponding pool test added

* format on millis {:.2} -> {}

* remove unused dependency bigint in

* remove bigint in rpc_cli

* Directly return None if tracing is disabled

* Address gumbles: release read locks as fast as possible

* getting started with replacing HardwareWalletManager

* trezor and ledger impls the new trait with some drawbacks

* Everything move to the new trait

* It required lifetime annotations in the trait because [u8] in unsized
* Lets now start moving entry point from HardwareWalletManager

* rename trait to Wallet

* move thread management to the actual wallets

* Moved thread management to each respective Wallet
* Cleaned up pub items that is needed to be pub
* Wallet trait more or less finished
* Cleaned up docs

* fix tests

* omit removed docs

* fix spelling, naming och remove old comments

* ledger test is broken, add correct logging format

* So locally on my machine Linux Ubuntu 17.10 the test doesn't panic but on the CI server libusb::Context::new()
fails which I don't understand because it has worked before
* Additionally the ledger test is optional so I lean toward ignoring it the CI Server

* ignore hardware tests by default

* more verbose checking in ledger test

* Pass on storage keys even if it is not modified

* typo: account and storage query

`to_pod_diff` builds both `touched_addresses` merge and storage keys merge.

* Fix tests

* Use state query directly because of suicided accounts

* Fix a RefCell borrow issue

* Address grumbles

* typo: remove unwanted empty line

* ensure_cached compiles with the original signature

* Don't panic in import_block if invalid rlp

* Remove redundant type annotation

* Replace RLP header view usage with safe decoding

Using the view will panic with invalid RLP. Here we use Rlp decoding directly which will return a `Result<_, DecoderError>`. While this path currently should not have any invalid RLP - it makes it safer if ever called with invalid RLP from other code paths.

* Remove expect and propagate rlp::DecoderErrors as TrieErrors

* Add SHL, SHR, SAR opcodes

* Add have_bitwise_shifting schedule flag

* Add all EIP tests for SHL

* Add SHR implementation and tests

* Implement SAR and add tests

* Add eip145transition config param

* Change map_or to map_or_else when possible

* Consolidate crypto functionality in `ethcore-crypto`.

- Move `ecdh`/`ecies` modules to `ethkey`.
- Refactor `ethcore-crypto` to use file per module.
- Replace `subtle` with `ethcore_crypto::is_equal`.
- Add `aes_gcm` module to `ethcore-crypto`.

* Rename `aes::{encrypt,decrypt,decrypt_cbc}` ...

... to `aes::{encrypt_128_ctr,decrypt_128_ctr,decrypt_128_cbc}`.
