This fixes issues where subsequent calls to vim.lsp.codelens.refresh()
would have no effect due to the buffer not getting cleared from the
active_refresh table.
Examples of how such scenarios would occur are:
- A textDocument/codeLens result yielded an error.
- The 'textDocument/codeLens' handler was overriden in such a way that
it no longer called vim.lsp.codelens.on_codelens().
(cherry picked from commit 94eb72cc44)
Refactors how required capabilities are detected and validated, and make
sure requests are only sent to clients that support it (and only fail if
no clients support the provided method).
The validation happens at the buf_request level, because we assume that
if someone is sending the request directly through the client, they know
what they're doing. Also, let unknown methods go through.
This is extracted from #12518 and closes#12755.
