Summary:
A bunch of different things was changed, but the most important (and need) change is that `UIManager` is now passed in the function as a regular reference, not as a `shared_ptr`. Besides that fact that passing this as `shared_ptr` is simply incorrect (because there is no ownership sharing/transferring here), we need this change because we cannot construct `shared_ptr` from `this` inside `UIManager` class (especially in the constructor).
Besides that:
* `const &` everything (correctness, explicit intention, performance);
* Names were unified with the rest of the code;
* `auto` everything;
* All JSI stuff is now explicitly prefixed with `jsi::`;
* `using` instead of `typedef` (modern C++ syntax);
* Lamdas instead of std::bind (same perfromance, much more clear and flexible);

Summary:
The spec says that `bridge_transfer` indicates that we "transfer ownership of the pointer" to ARC which implies that as soon this part of the code does not need the object, it will be deallocated. However, that's not what we want here. This object is actually already owned by another ARC-powered code somewhere else and the pointer to it was transferred as a raw pointer through the C++ world.
So, we want to keep the ownership of the object on the other side but still imply the lifetime of the object. So how can we do that? Simple, we have to use `bridge`.
Why? ARC is not magical, it's just automatic ref counting. And I think the only difference between `bridge` and `bridge_transfer` is how many refcounter's bumps will be added to the generated code. In the case of `bridge_transfer` it is zero, in the case of `bridge` it is one. So, initializing a new Objective-C variable that points to the shared resource we have to bump the counter once, so we have to use `bridge`.

Summary:
I realized that instead of using shared_ptr's type-erasure feature, we can make the EventHandler's destructor virtual and this itself will allow safe deallocation by a pointer to a base class.
We cannot use the same technic for EventTarget thought because having a weak_ptr to this is another feature of shared_ptr that we need.

Summary:
As we did in the previous diff, here we implemented `EventEmitter`'s ownership model as a `shared_ptr`. This change fixes problem with leaking `WeakObject`s which happens on hot-reload.
So, in short:
* `EventTargetWrapper` object owns `jsi::WeakObject` that can be converted to actual `jsi::Object` that represent event target in JavaScript realm;
* `EventTargetWrapper` and `jsi::WeakObject` objects must be deallocated as soon as native part does not need them anymore;
* `EventEmitter` objects retain `EventTarget` objects;
* `EventEmitter` can loose event target object in case if assosiated `ShadowNode` got unmounted (not deallocated); in this case `EventEmitter` is loosing possibility to dispatch event even if some mounting-layer code is still retaining it.

Summary:
Previously, we used special JSI bindings method to release an event handler (`JSIReleaseFabricEventHandler`). Now we expose this ownership model as a regular `std::shared_ptr`, so when the owner got deallocated, the event handler will be released automatically.
Why not use `unique_ptr`? `unique_ptr` is faster (and simpler) indeed, but it does not provide `type erasure` functionality that we need; to use `unique_ptr` we would have to make JSI an explicit Fabric dependency (we will probably end up with it eventually, but I this particular case is not a good reason for that).
All interactions with `eventHandler_` are done in a non-owning manner, so it's as performant as unique_ptr anyway.
(Please ignore all changes in JSCFabricUIManager.h/cpp files, we will delete them soon.)

Summary:
While these were intentionally used in the open, and never were abused, it has become a distraction whenever they are flagged.
We'll have to move this functionality to a service outside of Circle CI, as we cannot securely pass secrets to forks and PRs in Circle CI. By necessity, these PR analysis scripts must run alongside PRs.
The The controller you requested could not be found. token has already been revoked. The The controller you requested could not be found. token is not under our control, and is still valid as of this writing. The eslint token has public_repo scope, with no access to any private repos. It's no different than having a random account commenting on any public repo.
Unfortunately, revoking the The controller you requested could not be found. token affects React's use of this bot account as well.
---
Q: What does the React team need this token for?
A: It's used to analyze how a PR will impact the build size for React.
Q: What does the React Native team need this token for?
A: We do lightweight automated PR code reviews with it (eslint, flagging large PRs, etc)
Q: What can someone do with the access token?
A: The token was for the The controller you requested could not be found. GitHub account. The account has no privileged access to any organization, so in effect it's like having the token to a random GitHub account. The token has public_repo access scope, which allows it to interact with any public repository on GitHub. The attacker can leave comments on any issue, pull request, or commit, on any public open source repository on GitHub. They could spam or leave arbitrary messages. It's no different than using any random newly created GitHub account to do this, but the bot is named "React Linter", so people could have used it to make React look bad.
Q: Why didn't we just remove the token from the open source repositories? CircleCI allows you to use environment variables to keep secrets out of the repo.
A: We have configured CircleCI to hide environment variables from Circle CI jobs triggered by non-Facebook org forks and pull requests (otherwise, anyone could add a file to their fork that echoes $SUPER_SECRET and then read it from the Circle CI logs). This allows us to do things like publish to npm only on commits that actually land on the main repo, without letting random people do the same on their forks.
Q: Why can't we run these scripts on Circle CI jobs that do have access to secret environment variables?
A: It's by necessity. These scripts are meant to run on pull requests and forks. They're used to lint pull requests, after all.
Q: Why can't we run these scripts on internal Facebook infrastructure?
A: Automatic importing of arbitrary code from external sources into internal Facebook systems without a FB engineer's involvement is disallowed. We're happy to let Circle CI run unvetted code in this manner.
Q: What do other projects do in similar situations?
A: A common solution for open source projects that need to run scripts with access to GitHub without exposing the access token on CI is to use a private cloud server (i.e. a droplet in Digital Ocean, an instance on AWS...).
Q: Why don't we use the same infra used by react-native-bot to run react-linter?
A: React-Native-Bot runs once an hour or so, querying for recent issues and PRs. It does not use webhooks, and instead performs the same kind of search queries you'd use on GitHub, therefore it's not great for picking up when a PR has been updated. Circle CI is great for running scripts whenever a PR is created or updated, as Circle outages aside, we can be fairly certain a script will run any time a PR is updated. If you want to track build sizes, you really want to make sure any new commit added to a PR will trigger a re-run.
