Before, we've assumed that if call has no expression arguments, then
it's a 'returns()' call.
Now we check that we've resolved to overload of 'returns' from
ContractsDsl with zero parameters.
- Introduce ContractParsingDiagnosticsCollector
It allows us to make sure that we return 'null'-contract iff there's
some error. Note that it differs from previous behavior in two major
points:
a) if contract was unparsed, but no error were reported for
some reason, then generic error will be reported (previously we were
swallowing incorrect contract silently)
b) if there were some errors during parsing, return only 'null'
(previously, we could return some contract. It was unusable due to
errors in code, but we want to be extra-safe here)
- Introduce ContractCallContext to not pass a bunch of random arguments
around
- Make message of Error.CONTRACT_NOT_ALLOWED more flexible
'parseContract' is called only from
'ContractParsingServices.checkContractAndRecordIfPresent', and here we
already have checked that this call is indeed a contract call.
- Mark @ContractsDsl as @Experimental
- Move Contracts DSL out from 'internal' package
- Change visibility of ContractsDsl from 'internal' to 'public'

Avoid name clashes in cases such as
inline class Login(val login: String)
inline class Password(val password: String)
fun validate(login: Login) { ... }
fun validate(password: Password) { ... }
- Calling suspend functions is allowed
- Presence of suspend function type still makes declaration
unusable unless it belongs to a value parameter as a top-level type
containing less then three parameters
Still, warning should be emitted because they will become unsupported in 1.4
#KT-25683 In Progress
This commit effectively reverts
d386712903.
The reason is that when using a release language version, you can only
"see" the subset of a pre-release library which consists of released and
supported features, so reporting an error is not helpful there. Also, it
presents a problem currently when using kotlinc 1.3 (which is
pre-release) with language version 1.2 (stable) against the bundled
stdlib of version 1.3 (pre-release)
