Summary:
This paves the way for alternative transports (mac XPC, maybe messagepack?),
and also generally improves layering: testing ClangdLSPServer becomes less of
a pipe dream, we split up the JSONOutput monolith, etc.
This isn't a final state, much of what remains in JSONRPCDispatcher can go away,
handlers can call reply() on the transport directly, JSONOutput can be renamed
to StreamLogger and removed, etc. But this patch is sprawling already.
The main observable change (see tests) is that hitting EOF on input is now an
error: the client should send the 'exit' notification.
This is defensible: the protocol doesn't spell this case out. Reproducing the
current behavior for all combinations of shutdown/exit/EOF clutters interfaces.
We can iterate on this if desired.

Summary:
Instead of content-length, we delimit messages with ---.
This also removes the need for (most) dos-formatted test files.

Summary:
The goal here is again to make it easier to read and write the tests.
I've extracted `parseTextMarker` from CodeCompleteTests into an `Annotations`
class, adding features to it:
- as well as points `^s` it allows ranges `[[...]]`
- multiple points and ranges are supported
- points and ranges may be named: `$name^` and `$name[[...]]`
These features are used for the xrefs tests. This also paves the way for
replacing the lit diagnostics.test with more readable unit tests, using named
ranges.
Alternative considered: `TestSelectionRange` in clang-refactor/TestSupport
Main problems were:
- delimiting the end of ranges is awkward, requiring counting
- comment syntax is long and at least as cryptic for most cases
- no separate syntax for point vs range, which keeps xrefs tests concise
- Still need to convert to Position everywhere
- Still need helpers for common case of expecting exactly one point/range
(I'll probably promote the extra `PrintTo`s from some of the core Protocol types
into `operator<<` in `Protocol.h` itself in a separate, prior patch...)
