Make Gate.open and Gate.close EventCallable to allow users to call it in tests

Improve type validation for derived stores in fork
Add missed runtime validation for allSettled calls with derived units. This case was labeled as a type error, but was forgotten in runtime.

Support arbitary callbacks in scopeBind. Allows library developers to create better APIs in a way that is Fork API - compatible. https://github.com/effector/effector/pull/1016
Remove deprecated types for already removed $store.map overload. https://github.com/effector/effector/pull/1029

Skip enumerable prototype-inherited properties in useUnit(shape). Some badly-written polyfills might add such properties to built-ins like Array. https://github.com/effector/effector/pull/1023
Add missing depreaction tag to the one of useEvent overloads. https://github.com/effector/effector/pull/1030
Add useProvidedScope low level API for library developers. https://github.com/effector/effector/pull/1033

Improvements

Introduce EventCallable, StoreWritable and UnitTargetable types to allow users to express and understand what could be updated or called directly and what could not. Now createStore returns StoreWritable which can be passed to sample target and combine returns Store which will show type and runtime error (PR #966)
Improve error messages: now it includes unit names and locations so it will be useful to find errors in raw server logs or bundles with disabled source maps. To enable locations in errors use addLoc: true in babel-plugin. Usually the one wanted to enable this in development only so addLoc plugin option is disabled by default (PR #1015)
Add batch option to createWatch (PR #850)
Add @withease/factories to babel-plugin defaults (PR #995)
Add all patronum modules to babel-plugin defaults (PR #996)
Rename greedy to batch in sample. greedy: true becomes batch: false which is a better mental model for what this option do (PR #972)
Unify programmatic sid insertion in merge and restore (PR #969)
Allow domain to be used in attach without parent effect (PR #895)

Fix nullable type of .reinit, now it exists in StoreWritable and not exists in Store (PR #966)
Fix serialization of ignored stores (PR #903)
Fix race condition in parallel effect calls (PR #849)
Fix scope reading its initial values from current (not initial) store value (PR #909)
Fix duplicated combine calls (PR #916)
Fix reading stale value in attach (PR #1011)

Deprecate undefined as magical value to skip store updates, use skipVoid: true option in combine and map to enable old behavior. Getting rid of that edge case will allow to introduce lazy computations (issue #920)
Deprecate forward and guard in favor of sample (PR #913)
Deprecate reactSsr option in babel-plugin (PR #910)
Deprecate onlyChanges option in serialize (PR #907)
Deprecate raw object {[fx.sid]: Function} in fork handlers (PR #973)
Deprecate .watch with second argument in favor of sample (PR #906)
Deprecate .getType() - relic from ancient times which exists for redux compatibility (PR #899)
Deprecate effector/babel-plugin-react (PR #948)
Deprecate fork(domain) and hydrate(domain) - this api existed for traking units in scopes when Fork API was introduced, but starting from 22 version this is done automatically and domain is no longer required for that (PR #950)

Throw error when unit called from a pure function (PR #905)
Throw error when derived event is called (PR #905)
Throw error when fn in $store.map(fn) returns undefined in the initialization (issue #828)

Remove flow typings. In the beginning, the effector was written in flow, but now only types remained and they were extremely outdated due to lack of expertise in the technology. The flow community maintains bindings in a separate repository. (PR #912)
Remove deprecated effector/fork module (PR #842)
Remove deprecated createStoreObject alias for combine (PR #908)
Remove deprecated .thru method (PR #843)
Remove deprecated second argument with state from $store.map (PR #846)
Remove deprecated restore($store) support. This was an obscure feature when store is passed to method and returned without changes as is (PR #1018)
