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.
Added documentation to ProtocolHandlers.

This reverts commit r315242 and restores r315214.
To fix original failure, replaced non-portable `diff -Z` with portable
alternative: `diff -b`.

Summary:
They are now used in ClangdScheduler instead of deferred std::async
computations.
The results of `std::async` are much less effective and do not provide
a good abstraction for similar purposes, i.e. for storing additional callbacks
to clangd async tasks. The actual callback API will follow a bit later.

Summary:
ClangdServer now provides async code completion API.
It is still used synchronously by ClangdLSPServer, more work is needed
to allow processing other requests in parallel while completion (or
any other request) is running.

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.

There doesn't seem to be any real separation between the current three objects.
Feel free to reject this if you find the current style valuable, though.

Summary:
Completion results look much nicer without them.
Informative qualifiers are stored for every method from a base class, even when
calling those methods does not require any qualifiers. For example,
struct Foo { int foo(); };
struct Bar : Foo { };
void test() { Bar(). // Completion item label was 'Foo::foo' before,
// but inserted text was simply 'foo'.
// We now simply show 'foo' in completion item label.
They effectively cluttered the completion list without providing much value.

Summary:
Small extension to LSP to allow clients to use clangd to switch between C header files and source files.
Final version will use the completed clangd indexer to use the index of symbols to be able to switch from header to source file when the file names don't match.
