Summary:
This returns incremental highlights as a set of edits against the
previous highlights.
Server-side, we compute the full set of highlights, this just saves
wire-format size.
For now, the diff used is trivial: everything from the first change to
the last change is sent as a single edit.
The wire format is grungy - the replacement offset/length refer to
positions in the encoded array instead of the logical list of tokens.
We use token-oriented structs and translating to LSP forms when serializing.
This departs from LSP (but is consistent with semanticTokens today).
Tested in VSCode insiders (with a patched client to enable experimental
features).

Summary:
This ties to an LSP feature (diagnostic versioning) but really a lot
of the value is in being able to log what's happening with file versions
and queues more descriptively and clearly.
As such it's fairly invasive, for a logging patch :-\
Key decisions:
- at the LSP layer, we don't reqire the client to provide versions (LSP
makes it mandatory but we never enforced it). If not provided,
versions start at 0 and increment. DraftStore handles this.
- don't propagate magically using contexts, but rather manually:
addDocument -> ParseInputs -> (ParsedAST, Preamble, various callbacks)
Context-propagation would hide the versions from ClangdServer, which
would make producing good log messages hard
- within ClangdServer, treat versions as opaque and unordered.
std::string is a convenient type for this, and allows richer versions
for embedders. They're "mandatory" but "null" is a reasonable default.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
It simply shows the completed/total items on the background queue, e.g.
indexing: 233/1000
The denominator is reset to zero every time the queue goes idle.
The protocol is fairly complicated here (requires creating a remote "progress"
resource before sending updates). We implement the full protocol, but I've added
an extension allowing it to be skipped to reduce the burden on clients - in
particular the lit test takes this shortcut.
The addition of background index progress to DiagnosticConsumer seems ridiculous
at first glance, but I believe that interface is trending in the direction of
"ClangdServer callbacks" anyway. It's due for a rename, but otherwise actually
fits.

Summary:
The code tweaks are an implementation of mini-refactorings exposed
via the LSP code actions. They run in two stages:
- Stage 1. Decides whether the action is available to the user and
collects all the information required to finish the action.
Should be cheap, since this will run over all the actions known to
clangd on each textDocument/codeAction request from the client.
- Stage 2. Uses information from stage 1 to produce the actual edits
that the code action should perform. This stage can be expensive and
will only run if the user chooses to perform the specified action in
the UI.
One unfortunate consequence of this change is increased latency of
processing the textDocument/codeAction requests, which now wait for an
AST. However, we cannot avoid this with what we have available in the LSP
today.

Essentially, all code in the project is now made available by the LLVM

Standardize on the most common namespace setup in our *.cpp files:
using namespace llvm;
namespace clang {
namespace clangd {
void foo(StringRef) { ... }
And remove redundant llvm:: qualifiers. (Except for cases like
make_unique where this causes problems with std:: and ADL).
This choice is pretty arbitrary, but some broad consistency is nice.
This is going to conflict with everything. Sorry :-/
Squash the other configurations:
A)
using namespace llvm;
using namespace clang;
using namespace clangd;
void clangd::foo(StringRef);
This is in some of the older files. (It prevents accidentally defining a
new function instead of one in the header file, for what that's worth).
B)
namespace clang {
namespace clangd {
void foo(llvm::StringRef) { ... }
This is fine, but in practice the using directive often gets added over time.
C)
namespace clang {
namespace clangd {
using namespace llvm; // inside the namespace
This was pretty common, but is a bit misleading: name lookup preferrs
clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using
directive is).

improvements could be done in the future.
The index model doesn't contain quite enough symbols for this to cover

Summary:
This patch adds support for incremental document syncing, as described
in the LSP spec. The protocol specifies ranges in terms of Position (a
line and a character), and our drafts are stored as plain strings. So I
see two things that may not be super efficient for very large files:
- Converting a Position to an offset (the positionToOffset function)
requires searching for end of lines until we reach the desired line.
- When we update a range, we construct a new string, which implies
copying the whole document.
However, for the typical size of a C++ document and the frequency of
update (at which a user types), it may not be an issue. This patch aims
at getting the basic feature in, and we can always improve it later if
we find it's too slow.

Summary: Implemention of textDocument/hover as described in LSP definition.
This patch adds a basic Hover implementation. When hovering a variable,
function, method or namespace, clangd will return a text containing the
declaration's scope, as well as the declaration of the hovered entity.
For example, for a variable:
Declared in class Foo::Bar
int hello = 2
For macros, the macro definition is returned.
This patch doesn't include:
- markdown support (the client I use doesn't support it yet)
- range support (optional in the Hover response)
- comments associated to variables/functions/classes
They are kept as future work to keep this patch simpler.
I added tests in XRefsTests.cpp. hover.test contains one simple
smoketest to make sure the feature works from a black box perspective.

Summary:
o Collect suitable #include paths for index symbols. This also does smart mapping
for STL symbols and IWYU pragma (code borrowed from include-fixer).
o For global code completion, add a command for inserting new #include in each code
completion item.

Summary:
The assertion will point directly to misbehaving code, so that
debugging related problems (like the one fixed by r325029) is easier.

Summary:
Instead of passing Context explicitly around, we now have a thread-local
Context object `Context::current()` which is an implicit argument to
every function.
Most manipulation of this should use the WithContextValue helper, which
augments the current Context to add a single KV pair, and restores the
old context on destruction.
Advantages are:
- less boilerplate in functions that just propagate contexts
- reading most code doesn't require understanding context at all, and
using context as values in fewer places still
- fewer options to pass the "wrong" context when it changes within a
scope (e.g. when using Span)
- contexts pass through interfaces we can't modify, such as VFS
- propagating contexts across threads was slightly tricky (e.g.
copy vs move, no move-init in lambdas), and is now encapsulated in
the threadpool
Disadvantages are all the usual TLS stuff - hidden magic, and
potential for higher memory usage on threads that don't use the
context. (In practice, it's just one pointer)

Summary:
o Replace the existing clangd::URI with a wrapper of FileURI which also
carries a resolved file path.
o s/FileURI/URI/
o Get rid of the URI hack in vscode extension.

Summary:
This adds checks that our diagnostics emit correct ranges in a bunch of cases,
as promised in D41118.
The diagnostics-preamble test is also converted and extended to be a little more
precise.
diagnostics.test stays around as the smoke test for this feature.

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
- Protocol.cpp gets a bit shorter
Sorry for the giant patch, it's prety mechanical though

Summary:
This makes the parse() functions about as short as they can be given the
current signature, and moves all array-traversal etc code to a
central location.
We keep the ability to distinguish between optional and required fields:
and we don't propagate parse errors for optional fields.
I've made most fields required per the LSP spec - the looseness we had
here was mostly a historical accident I think.
