caba1cb2e1 Fix crash when calling substring() on a string containing emoji. (#23609)
Summary:
Fixes #23459. It is not legal to write the character array of a std::string, and can result in undefined behavior.

[General] [Fixed] - Crash when substring intersects with emoji

78be6efda9 JSI: Minor tweaks for building on MSVC (#23367)
Summary:
This pull request makes two minor changes to `jsi.h`:

 * Tweak the `JSI_EXPORT` macro to automatically set itself to an empty value if `_MSC_VER` is defined - like how was done by acoates-ms [here](8beb4bb58a/ReactCommon/cxxreact/JSBigString.h (L15-L21)).
 * Tweak the call to constructor `Pointer(Runtime::PointerValue* ptr)` in the constructor for `PropNameID`. I am not sure why MSVC wasn't working with the original version, but it compiles after I tweak that.

bdb084e8a8 Check for thread consistency in JSCRuntime
Summary:
In the version of JSC on iOS 11, creating a JSContext on one
thread and using it on another can trigger subtle and nearly
impossible to debug reentrancy-related crashes in the VM (see
https://bugs.webkit.org/show_bug.cgi?id=186827).  In !NDEBUG builds,
check for this case and throw an exception, so it can be detected
early.

bf2500e38e Switch to synchronous strategy for unprotect
Summary:
Older versions of JSC (ios 11 and before) have a bug which I
believe the ProtectionQueue mechanism tickles:
https://bugs.webkit.org/show_bug.cgi?id=186827

This removes the ProtectionQueue and replaces it with an atomic flag
to avoid calling unprotect after VM shutdown.

This also fixes a race condition in shutdown.

6370b86c1f Get RNTester to compile and run
Summary:
This diff includes a few changes:
1. Move the headers inside `jsiexecutor` into `jsiexecutor/jsireact`. As far as I'm aware, the Android ndk build system isn't flexible enough to support header namespaces, so we can't just expose the headers inside the `jsiexecutor` directory under the `jsireact` namespace. Therefore, I moved the headers to `jsiexecutor/jsireact`, and added `jsiexecutor` to the header search path.  This was the easiest way to simulate `jsireact` namespace.
2. Setup the Android.mk files to get RNTester compiling and running.
3. Introduce a `jscexecutor` module to make `JSCExecutor.java` execute without throwing.

**Note:** Moving the header files inside `jsiexecutor` probably breaks the iOS builds and internal builds. I'll fix those in subsequent diffs on this stack.
