Kernel32 Threading API

• CreateThread, CreateRemoteThread, CreateRemoteThreadEx
• CreateThreadFlags enum
• Tests
• FriendlyFlags.NativeInt flag applicable to IntPtr and UIntPtr types that are used as a proxy for Win32 SIZE_T type.
  • A future update will add code-gen for generating appropriate overloads leverage C# 9's nint/nuint.
    • We need an issue for this.
  • We probably also need an issue to inventory methods that have parameters or return-types that logically map to Wn32 SIZE_T and tag them with FriendlyFlag.NativeInt.

Fixes #428

Thanks for contributing!

Addressed comments so far. Outstanding at this time:

• Should we keep using CreateProcessFlags or create a new CreateThreadFlags enum
• Add FriendlyFlags.NativeInt for future use.
  • Bring back SIZE_T if possible to write one reliably.

I couldn't tag void* parameters with FriendlyFlags.Optional or FriendlyFlags.Bidirectional. I'm assuming that this is normal/expected?

True, void* has no non-pointer alternative, so friendly attributes don't work on them.

Create a new one.

Add FriendlyFlags.NativeInt for future use. Bring back SIZE_T if possible to write one reliably.

Future use option sounds good. The SIZE_T struct doesn't sound enticing given @jkotas' warning.

Just one question about that test delegate
