* Update Flow to 0.84
* Fix violations
* Use inexact object syntax in files from fbsource
* Fix warning extraction to use a modern parser
* Codemod inexact objects to new syntax
* Tighten types that can be exact
* Revert unintentional formatting changes from codemod
* Replace all warning/lowPriWarning with console calls
* Replace console.warn/error with a custom wrapper at build time
* Fail the build for console.error/warn() where we can't read the stack
* prep for codemod
* prep warnings
* rename lint rules
* codemod for ifs
* shim www functions
* Handle more cases in the transform
* Thanks De Morgan
* Run the codemod
* Delete the transform
* Fix up confusing conditions manually
* Fix up www shims to match expected API
* Also check for low-pri warning in the lint rule
* Rename lowPriorityWarning to lowPriorityWarningWithoutStack
This maintains parity with the other warning-like functions.
* Duplicate the toWarnDev tests to test toLowPriorityWarnDev
* Make a lowPriorityWarning version of warning.js
* Extract both variants in print-warning
Avoids parsing lowPriorityWarning.js itself as the way it forwards the
call to lowPriorityWarningWithoutStack is not analyzable.
Upgraded from Babel 6 to Babel 7.
The only significant change seems to be the way `@babel/plugin-transform-classes` handles classes differently from `babel-plugin-transform-es2015-classes`. In regular mode, the former injects a `_createClass` function that increases the bundle size, and in the latter it removes the safeguard checks. However, this is okay because we don't all classes in new features, and we want to deprecate class usage in the future in the react repo.

- redoes #15431 from scratch, taking on the feedback there
- unifies the messaging between "deprecated" and UNSAFE_ lifecycle messages. It reorganizes ReactStrictModeWarnings.js to capture and flush all the lifecycle warnings in one procedure each.
- matches the warning from ReactPartialRenderer to match the above change
- passes all the tests
- this also turns on `warnAboutDeprecatedLifecycles` for the test renderer. I think we missed doing so it previously. In a future PR, I'll remove the feature flag altogether.
- this DOES NOT do the same treatment for context warnings, I'll do that in another PR too
* Use relative paths in packages/react
* Use relative paths in packages/react-art
* Use relative paths in packages/react-cs
* Use relative paths in other packages
* Fix as many issues as I can
This uncovered an interesting problem where ./b from package/src/a would resolve to a different instantiation of package/src/b in Jest.
Either this is a showstopper or we can solve it by completely fobbidding remaining /src/.
* Fix all tests
It seems we can't use relative requires in tests anymore. Otherwise Jest becomes confused between real file and symlink.
https://github.com/facebook/jest/issues/3830
This seems bad... Except that we already *don't* want people to create tests that import individual source files.
All existing cases of us doing so are actually TODOs waiting to be fixed.
So perhaps this requirement isn't too bad because it makes bad code looks bad.
Of course, if we go with this, we'll have to lint against relative requires in tests.
It also makes moving things more painful.

* Add back caught error and other checks to 'lowPriorityWarning'
**what is the change?:**
This change makes 'lowPriorityWarning' an exact copy of 'warning.js' from
e66ba20ad5/packages/fbjs/src/__forks__/warning.js
where before we had skipped some checks from that module.
- Adds an error which we catch, in order to let people find the error and resulting stack trace when using devtools with 'pause on caught errors' checked.
- Adds check that 'format' argument is passed
**why make this change?:**
- To maintain a closer fork to 'warning.js'
- To allow easier debugging using 'pause on caught errors'
- To validate inputs to 'lowPriorityWarning'
**test plan:**
`yarn test`
**issue:**
* Update 'print-warnings' script to include 'lowPriorityWarning' output
**what is the change?:**
We print the logs from 'lowPriorityWarning' as well as 'warning' from the 'print-warnings' script.
NOTE: This PR is branching off of https://github.com/facebook/react/pull/9754
**why make this change?:**
We want to use the same process of white/blacklisting warnings with 'lowPriorityWarning' that we do with 'warning'.
**test plan:**
This is not super easy to test unless we are doing a sync with FB afaik. I plan on running a sync in the next few days, or next week at latest, for the sake of not landing big things on a Friday. That will be the actual test of this.
**issue:**
