Netbeans LSP Client (preview)

This is an fork of the embedded Netbeans LSP client which allows the usage of any Language Server Protocol implementation.

Our motivation was driven by the idea of C# support for Netbeans. Unfortunately the current LSP client doesn't work with Omnisharp which is the reference LSP server for C#. Furthermore the plan is, to make our LSP client implementation stable and give it back to the apache Netbeans community.

current changes are

• upgrade eclipse LSP4j libraries which supports the latest LSP spec (LSP 3.16.0)
• fix "document not locked" exception in HyperlinkProvider
• implement missing code because of LSP upgrade
  • alternative MarkOccurrences based on references if highlighting provider is not available
  • implement Hover client endpoint (prototyp)
  • implement CodeLens client endpoint (prototyp)
  • implement Signature client endpoint (prototyp)
• make it work with Omnisharp
  • set PID
  • send initialized msg
• LSP Server logging UI
