* Add lsp signature help
* Do not move signature help popup on multiple triggers
* Highlight current parameter in signature help
* Auto close signature help
* Position signature help above to not block completion
* Update signature help on backspace/insert mode delete
* Add lsp.auto-signature-help config option
* Add serde default annotation for LspConfig
* Show LSP inactive message only if signature help is invoked manually
* Do not assume valid signature help response from LSP
Malformed LSP responses are common, and these should not crash the
editor.
* Check signature help capability before sending request
* Reuse Open enum for PositionBias in popup
* Close signature popup and exit insert mode on escape
* Add config to control signature help docs display
* Use new Margin api in signature help
* Invoke signature help on changing to insert mode
We should not depend on jsonrpc-core anymore:
* The project just announced it's no longer actively maintained[^1],
preferring their new implementation in `jsonrpsee`.
* The types are too strict: we would benefit from removing some
`#[serde(deny_unknown_fields)]` annotations to allow language
servers that disrespect the spec[^2].
* We don't use much of the project. Just the types out of core.
These are easy to embed directly into the `helix-lsp` crate.

* allows passing extra formatting options to LSPs
- adds optional field 'format' to [[language]] sections in 'languages.toml'
- passes specified options the LSPs via FormattingOptions
* cleaner conversion of formatting properties
* move formatting options inside lsp::Client
* cleans up formatting properties merge
* Send active diagnostics to LSP when requesting code actions.
This allows for e.g. clangd to properly send the quickfix code actions
corresponding to those diagnostics as options.
The LSP spec v3.16.0 introduced an opaque `data` member that would allow
the server to persist arbitrary data between the diagnostic and the code
actions request, but this is not supported yet by this commit.
* Reuse existing range_to_lsp_range functionality
* Added option to provide a custom config file to the lsp.
* Simplified lsp loading routine with anyhow
* Moved config to language.toml
* Fixed test case
* Cargo fmt
* Revert now-useless changes
* Renamed custom_config to config
