Summary:
Clangd currently doesn't cache any indexing failures, which results in
retrying those failed files even if their contents haven't changed.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Currently, there's no way of knowing about header files
using compilation database, since it doesn't contain header files as entries.
Using this information, restoring from cache using compile commands becomes
possible instead of doing directory traversal. Also, we can issue indexing
actions for out-of-date headers even if source files depending on them haven't
changed.

Summary:
Instead of passing around a list of supported URI schemes in clangd, we
expose an interface to convert a path to URI using any compatible scheme
that has been registered. It favors customized schemes and falls
back to "file" when no other scheme works.
Changes in this patch are:
- URI::create(AbsPath, URISchemes) -> URI::create(AbsPath). The new API finds a
compatible scheme from the registry.
- Remove URISchemes option everywhere (ClangdServer, SymbolCollecter, FileIndex etc).
- Unit tests will use "unittest" by default.
- Move "test" scheme from ClangdLSPServer to ClangdMain.cpp, and only
register the test scheme when lit-test or enable-lit-scheme is set.
(The new flag is added to make lit protocol.test work; I wonder if there
is alternative here.)

Summary:
Puts the digest of the source file that generated the index into
serialized index and stores them back on load, if exists.

Summary:
It's slow, and the open-source reduce implementation doesn't scale properly.
While here, tidy up some dead headers and comments.

Summary: Soon we can drop support for MR-via-YAML.
I need to modify some out-of-tree versions to use the library, first.

Summary:
Interface is in one file, implementation in two as they have little in common.
A couple of ad-hoc YAML functions left exposed:
- symbol -> YAML I expect to keep for tools like dexp
- YAML -> symbol is used for the MR-style indexer, I think we can eliminate
this (merge-on-the-fly, else use a different serialization)

Summary:
This is intended to replace the current YAML format for general use.
It's ~10x more compact than YAML, and ~40% more compact than gzipped YAML:
llvmidx.riff = 20M, llvmidx.yaml = 272M, llvmidx.yaml.gz = 32M
It's also simpler/faster to read and write.
The format is a RIFF container (chunks of (type, size, data)) with:
- a compressed string table
- simple binary encoding of symbols (with varints for compactness)
It can be extended to include occurrences, Dex posting lists, etc.
There's no rich backwards-compatibility scheme, but a version number is included
so we can detect incompatible files and do ad-hoc back-compat.
Alternatives considered:
- compressed YAML or JSON: bulky and slow to load
- llvm bitstream: confusing model and libraries are hard to use. My attempt
produced slightly larger files, and the code was longer and slower.
- protobuf or similar: would be really nice (esp for back-compat) but the
dependency is a big hassle
- ad-hoc binary format without a container: it seems clear we're going
to add posting lists and occurrences here, and that they will benefit
from sharing a string table. The container makes it easy to debug
these pieces in isolation, and make them optional.
