Summary:
Implementation of DidChangeConfiguration notification handling in
clangd. This currently only supports changing one setting: the path of
the compilation database to be used for the current project. In other
words, it is no longer necessary to restart clangd with a different
command line argument in order to change the compilation database.

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:
- GlobalCompilationDatabase now returns a single command (that's all we use)
- fallback flags are now part of the GlobalCompilationDatabase.
There's a default implementation that they can optionally customize.
- this allows us to avoid invoking the fallback logic on two separate codepaths
- race on extra flags fixed by locking the mutex
- made GCD const-correct (DBGCD does have mutating methods)

Summary: Adds compileCommands command line argument to specify an absolute path directly to the requested compile_commands.json for flags.

Summary:
This patch adds the ability to specify user-defined extra flags per opened file
through the LSP layer. This is a non-standard extension to the protocol.
I've already created a feature request about it for upstream lsp:
https://github.com/Microsoft/language-server-protocol/issues/255
The particular use-case is ycmd, which has a python script for figuring out
extra flags per file:

Summary:
This commit restores r303067(reverted by r303094) and fixes the 'formatting.test'
failure.
The failure is due to destructors of `ClangdLSPServer`'s fields(`FixItsMap` and
`FixItsMutex`) being called before destructor of `Server`. It led to the worker
thread calling `consumeDiagnostics` after `FixItsMutex` and `FixItsMap`
destructors were called.
Also, clangd is now run with '-run-synchronously' flag in 'formatting.test'.
