part of check-clang-tools.
Summary:
Motivation:
- this layout is a pain to work with
- without a common root, it's painful to express things like "disable clangd" (D61122)
- CMake/lit configs are a maintenance hazard, and the more the one-off hacks
for various tools are entangled, the more we see apathy and non-ownership.
This attempts to use the bare-minimum configuration needed (while still
supporting the difficult cases: windows, standalone clang build, dynamic libs).
In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in.
The logic in these files is now minimal.
(Much of clang-tools-extra's lit configs can probably be cleaned up by reusing
lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of
LDPATH mangling. I haven't attempted to fix any of those).
Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.

Summary:
An AST-based approach is used to retrieve the document symbols rather than an
in-memory index query. The index is not an ideal fit to achieve this because of
the file-centric query being done here whereas the index is suited for
project-wide queries. Document symbols also includes more symbols and need to
keep the order as seen in the file.

Summary:
This is a basic implementation of the "workspace/symbol" request which is
used to find symbols by a string query. Since this is similar to code completion
in terms of result, this implementation reuses the "fuzzyFind" in order to get
matches. For now, the scoring algorithm is the same as code completion and
improvements could be done in the future.
The index model doesn't contain quite enough symbols for this to cover
common symbols like methods, enum class enumerators, functions in unamed
namespaces, etc. The index model will be augmented separately to achieve this.

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:
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.

Summary:
Make clangd handle "textDocument/rename" request. The rename
functionality comes from the "local-rename" sub-tool of clang-refactor.
Currently clangd only supports local rename (only symbol occurrences in
the main file will be renamed).

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...

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.

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.
