Create a `ThreadsafeFS` in the `DraftStore` that overlays the dirty file contents over another `ThreadsafeFS`.
This provides a nice thread-safe interface for using dirty file contents throughout the codebase, for example cross file refactoring.
Creating a Filesystem view will overlay a snapshot of the current contents, so if the draft store is updated while the view is being used, it will contain stale contents.

This was causing TSan failures due to a race on vptr during destruction,
see
https://lab.llvm.org/buildbot/#/builders/131/builds/6579/steps/6/logs/FAIL__Clangd_Unit_Tests__LSPTest_FeatureModulesThr.
The story is, during the execution of a destructor all the virtual
dispatches should resolve to implementations in the class being
destroyed, not the derived ones. And LSPTests will log some stuff during
destruction (we send shutdown/exit requests, which are logged), which is
a virtual dispatch when LSPTest is derived from clang::clangd::Logger.
It is a benign race in our case, as gtests that derive from LSPTest
doesn't override the `log` method. But still during destruction, we
might try to update vtable ptr (due to being done with destruction of
test and starting destruction of LSPTest) and read from it to dispatch a
log message at the same time.
This patch fixes that race by moving `log` out of the vtable of
`LSPTest`.

As pointed out in D96244, "Module" is already pretty overloaded to refer

FeatureModule is a bit of a mouthful but it's pretty self-descriptive.

Clangd uses codecompletion limit as the limit for workspacesymbols, so
in theory this should only be an order of magnitude slower than a
codecompletion request with empty identifier (as code completion limits
the available symbols).
This is also what LSP suggests "Clients may send an empty string here to request all symbols.".
Clangd doesn't really fulfill the "all" part of that statement, but we

ClangdServer already gets notified of every change, so it makes sense for it to

This is a step towards having ClangdServer expose a FS that includes dirty
buffers: D94554

- version is now optional for ClangdServer, to preserve our existing fuzziness
in this area (missing version ==> autoincrement)
- ClangdServer::format{File,Range} are now more regular ClangdServer functions
that don't need the code passed in. While here, combine into one function.
- incremental content update logic is moved from DraftStore to
ClangdLSPServer, with most of the implementation in SourceCode.cpp.

Browsing macro-generated symbols is confusing.
On the one hand, it seems very *useful* to be able to see the summary of
symbols that were generated.
On the other hand, some macros spew a lot of confusing symbols into the
namespace and when used repeatedly (ABSL_FLAG) can create a lot of spam
that's hard to navigate.
Design constraints:
- the macro expansion tree need not align with the AST, though it often
does in practice.
We address this by defining the nesting based on the *primary*
location of decls, rather than their ranges.
- DocumentSymbol.children[*].range should nest within DocumentSymbol.range
(This constraint is not in LSP "breadcrumbs" breaks without it)
We adjust macro ranges so they cover their "children", rather than
just the macro expansion
- LSP does not have a "macro expansion" symbolkind, nor does it allow a
symbol to have no kind. I've arbitrarily picked "null" as this is
unlikely to conflict with anything useful.
This patch makes all macros and children visible for simplicity+consistency,
though in some cases it may be better to elide the macro node.
We may consider adding heuristics for this in future (e.g. when it expands
to one decl only?) but it doesn't seem clear-cut to me.

Currently our strategy for getting header compile flags is something like:
A) look for flags for the header in compile_commands.json
This basically never works, build systems don't generate this info.
B) try to match to an impl file in compile_commands.json and use its flags
This only (mostly) works if the headers are in the same project.
C) give up and use fallback flags
This kind of works for stdlib in the default configuration, and
otherwise doesn't.
Obviously there are big gaps here.
This patch inserts a new attempt between A and B: if the header is
transitively included by any open file (whether same project or not),
then we use its compile command.
This doesn't make any attempt to solve some related problems:
- parsing non-self-contained header files in context (importing PP state)

Current indexes merge logic skip data from the static index if the file is in the dynamic index, but sometimes the dynamic index does not contain references (e.g. preamble (dynamic) index vs background (static) index).

This is a step towards allowing CDB behavior to being configurable.
Previously ClangdServer itself created the configs and installed them into
contexts. This was natural as it knows how to deal with resulting diagnostics.
However this prevents config being used in CDB, which must be created before
ClangdServer. So we extract the context provider (config loader) as a separate
object, which publishes diagnostics to a ClangdServer::Callbacks itself.
Now initialization looks like:
- First create the config::Provider
- Then create the ClangdLSPServer, passing config provider
- Next, create the context provider, passing config provider + diagnostic callbacks
- now create the CDB, passing context provider
- finally create ClangdServer, passing CDB, context provider, and diagnostic callbacks

This is on the critical path (it blocks getting the compile command for

It's not trivially fast: it involves processing all filenames in the CDB

a compilation error. With this fix, we pick a point after such
definition in translation unit.
This is not a perfect solution. For example, it still doesn't handle
"using namespace" directives. It is, however, a significant improvement.

Seeing an implicit this in the AST is pretty confusing I think.
While here, also mention when `this` is const.

This was confusing, as testRoot on windows results in C:\\clangd-test
and testPath generated with posix explicitly still contained backslashes.
This patch ensures not only the relative part, but the whole final result
respects passed in Style.

An index implementation that can dispatch to a variety of indexes
depending on the file path. Enables clangd to work with multiple indexes in the
same instance, configured via config files.
Depends on D90749, D90746

Compilation logic for External blocks. A few of the high level points:
- Requires exactly one-of File/Server at a time:
- Server is ignored in case of both, with a warning.
- Having none is an error, would render ExternalBlock void.
- Ensures mountpoint is an absolute path:
- Interprets it as relative to FragmentDirectory.
- Defaults to FragmentDirectory when empty.
- Marks Background as Skip.
Depends on D90748.

Enable configuration of remote and static indexes through config files
in addition to command line arguments.

First step of implementing clang-tidy configuration into clangd config.
This is just adding support for reading and verifying the clang tidy options from the config fragments.
No support is added for actually using the options within clang-tidy yet.
That will be added in a follow up as its a little more involved.

This is a mass-market version of the "dump AST" tweak we have behind
-hidden-features.
I think in this friendlier form it'll be useful for people outside clang
developers, which would justify making it a real feature.
It could be useful as a step towards lightweight clang-AST tooling in clangd
itself (like matcher-based search).
Advantages over the tweak:
- simplified information makes it more accessible, likely somewhat useful
without learning too much clang internals
- can be shown in a tree view
- structured information gives some options for presentation (e.g.
icon + two text colors + tooltip in vscode)
- clickable nodes jump to the corresponding code
Disadvantages:
- a bunch of code to handle different node types
- likely missing some important info vs dump-ast due to brevity/oversight
- may end up chasing/maintaining support for the long tail of nodes

If there is a "-verify" flag in the compile command, clangd will crash
(hit the assertion) inside the `~VerifyDiagnosticConsumer` (Looks like our
compiler invocation doesn't setup correctly?).
This patch disables the verify mode as it is rarely useful in clangd.

Address Sanitizer crashes on large allocations:
