Sam McCall b536a2a5ba [clangd] Expose offset <-> LSP position functions, and fix bugs
Summary:
- Moved these functions to SourceCode.h
- added unit tests
- fix off by one in positionToOffset: Offset - 1 in final calculation was wrong
- fixed formatOnType which had an equal and opposite off-by-one
- positionToOffset and offsetToPosition both consistently clamp to beginning/end
  of file when input is out of range
- gave variables more descriptive names
- removed windows line ending fixmes where there is nothing to fix
- elaborated on UTF-8 fixmes

This will conflict with Eric's D41281, but in a pretty easy-to-resolve way.

Sam McCall 8111d3b89c [clangd] Emit ranges for clangd diagnostics, and fix off-by-one positions
Summary:
 - when the diagnostic has an explicit range, we prefer that
 - if the diagnostic has a fixit, its RemoveRange is our next choice
 - otherwise we try to expand the diagnostic location into a whole token.
   (inspired by VSCode, which does this client-side when given an empty range)
 - if all else fails, we return the zero-width range as now.
   (clients react in different ways to this, highlighting a token or a char)
 - this includes the off-by-one fix from D40860, and borrows heavily from it

Summary:
 - JSON<->Obj interface is now ADL functions, so they play nicely with enums
 - recursive vector/map parsing and ObjectMapper moved to JSONExpr and tested
 - renamed (un)parse to (de)serialize, since text -> JSON is called parse

Sam McCall ec109029b1 [clangd] Switch from YAMLParser to JSONExpr
Summary:
 - Converted Protocol.h parse() functions to take JSON::Expr.
   These no longer detect and log unknown fields, as this is not that
   useful and no longer free.
   I haven't changed the error handling too much: fields that were
   treated as optional before are still optional, even when it's wrong.
   Exception: object properties with the wrong type are now ignored.
 - Made JSONRPCDispatcher parse using json::parse
 - The bug where 'method' must come before 'params' in the stream is
 fixed as a side-effect. (And the same bug in executeCommand).
 - Some parser crashers fixed as a side effect.
   e.g. https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3890
 - The debug stream now prettyprints the input messages with --pretty.
 - Request params are attached to traces when tracing is enabled.
 - Fixed some bugs in tests (errors tolerated by YAMLParser, and
 off-by-ones in Content-Length that our null-termination was masking)
 - Fixed a random double-escape bug in ClangdLSPServer (it was our last
 use of YAMLParser!)

Sam McCall a40371bcb6 [clangd] Support returning a limited number of completion results.
Summary:
All results are scored, we only process CodeCompletionStrings for the winners.
We now return CompletionList rather than CompletionItem[] (both are valid).
sortText is now based on CodeCompletionResult::orderedName (mostly the same).

This is the first clangd-only completion option, so plumbing changed.
It requires a small clangd patch (exposing CodeCompletionResult::orderedName).

Sam McCall dd0566bb2c Adds a json::Expr type to represent intermediate JSON expressions.
Summary:
This form can be created with a nice clang-format-friendly literal syntax,
and gets escaping right. It knows how to call unparse() on our Protocol types.
All the places where we pass around JSON internally now use this type.

Object properties are sorted (stored as std::map) and so serialization is
canonicalized, with optional prettyprinting (triggered by a -pretty flag).
This makes the lit tests much nicer to read and somewhat nicer to debug.
(Unfortunately the completion tests use CHECK-DAG, which only has
line-granularity, so pretty-printing is disabled there. In future we
could make completion ordering deterministic, or switch to unittests).

Compared to the current approach, it has some efficiencies like avoiding copies
of string literals used as object keys, but is probably slower overall.
I think the code/test quality benefits are worth it.

This patch doesn't attempt to do anything about JSON *parsing*.
It takes direction from the proposal in this doc[1], but is limited in scope
and visibility, for now.
I am of half a mind just to use Expr as the target of a parser, and maybe do a
little string deduplication, but not bother with clever memory allocation.
That would be simple, and fast enough for clangd...

Marc-Andre Laperle e7ec16aaa6 [clangd] Handle clangd.applyFix server-side
Summary:
When the user selects a fix-it (or any code action with commands), it is
possible to let the client forward the selected command to the server.
When the clangd.applyFix command is handled on the server, it can send a
workspace/applyEdit request to the client. This has the advantage that
the client doesn't explicitly have to know how to handle
clangd.applyFix. Therefore, the code to handle clangd.applyFix in the VS
Code extension (and any other Clangd client) is not required anymore.

Ilya Biryukov 0d9b8a3ee8 [clangd] Handle exit notification (proper shutdown)
Summary:
This changes the onShutdown handler to do essentially nothing (for now), and
instead exits the runloop when we receive the exit notification from the client.

Some clients may wait on the reply from the shutdown request before sending an
exit notification. If we exit the runloop already in the shutdown request, a
client might block forever.

This also gives us the opportunity to do any global cleanups and/or
serializations of PCH preambles to disk, but I've left that out for now.

See the LSP protocol documentation for details.

Summary:
Make the ProtocolHandlers glue between JSONRPCDispatcher and
ClangdLSPServer generic.
Eliminate small differences between methods, de-emphasize the unimportant
distinction between notifications and methods.

ClangdLSPServer is no longer responsible for producing a complete
JSON-RPC response, just the JSON of the result object. (In future, we
should move that JSON serialization out, too).
Handler methods now take a context object that we may hang more
functionality off in the future.

Marc-Andre Laperle bf11424b7f [clangd] Handle workspace/didChangeWatchedFiles
Summary:
The client can send notifications when it detects watched files have
changed. This patch adds the protocol handling for this type of notification.
For now, the notification will be passed down to the ClangdServer, but it will
not be acted upon. However, this will become useful for the indexer to react
to file changes.
The events could also potentially be used to invalidate other caches
(compilation database, etc).

This change also updates the VSCode extension so that it sends the events.
