Support Custom Link Matchers in Terminal via API

[mdrichardson]

I would like to be able to register custom link matchers in the terminal when authoring VS Code extensions.

For example, the Bot Framework Emulator uses a custom URI Protocol, bfemulator://. I would like the ability to register a custom link matcher so that when bfemulator://** is displayed in the terminal, a user can ctrl+click it to open.

Similar Issues:

• Allow custom link matchers to be registered in terminal API #18454 - Closed as out-of-scope, although I'm not sure why. There was some talk about this maybe being supported in Tasks, but I haven't found a way to implement it.
• expose registerLinkMatcher api in terminal render #70411 - @Tyriar mentioned he doesn't want expose the registerLinkMatcher API, but didn't really explain why. This was closed as a duplicate, but I'm also not sure why.
• Support terminal link matchers in tasks v2 #21928 - This one is still open, but hasn't been updated since Dec 2017.

No plans to add this, the reason #70411 was closed as the underlying registerLinkMatcher API will likely change, so naturally I don't want to propagate it into the VS Code API until that is worked out (depends on what happens in xtermjs/xterm.js#583).

Thanks for creating this issue! We figured it's covering the same as another one we already have. Thus, we closed this one as a duplicate. You can search for existing issues here. See also our issue reporting guidelines.
