Remove unused PInvokes #2828

Open edwardneal opened 1 month ago

This is the first step of a process to merge PInvokes between the .NET and .NET Framework projects. I've started by removing most of the unused PInvokes from both projects. There shouldn't be any surprises in CI.

I've also changed SqlUtil's SocketDidNotThrow method to throw an Exception rather than an InternalException. This was the only reference to InternalException which for the .NET 8.0 target, so this change means that when .NET 6.0 support is dropped, everything in the netcore/src/Common/src/System folder except for NotImplemented.cs can be removed.

The next step of the PInvoke merge process will be more involved. What's the coding standard for this? dotnet/runtime uses one folder per OS, one subfolder per DLL, one file per method, and there are quite a few files which fit this pattern. Other parts of the .NET project have a single file containing every PInvoke for a single DLL (the SNI DLL.)

Step 2 will be to merge the OS PInvokes which are needed for .NET Framework and .NET 8.0, and step 3 is currently to address the native SNI PInvokes. At the point of step 3, I'd also like to change the .NET Framework project to refer to Microsoft.Data.SqlClient.SNI.runtime, so it matches the .NET project. This might depend on #2671.
