sccache 0.17.0

Summary

sccache 0.17.0 is a significant release: it introduces a new client-side architecture.

Until now, every compilation was handed off to the long-lived sccache server, which did the cache
lookup and ran the compiler. In client-side mode, the client process does that work itself - the
server is only consulted for the shared state it owns (compiler info, dist client, stats). This
removes a round-trip and the server-side bottleneck, and gives noticeably better results on
developer workstations.

Client-side mode is opt-in for now: enable it with the SCCACHE_CLIENT_SIDE environment variable
(or the client_side_mode config key). See docs/Architecture.md
for the details.

Other highlights:

• Response files: gcc/clang builds using quoted @response files are now cached and
  distributed correctly (#​2755, #​2772), and Rust @argfile arguments are supported (#​2782).
• Distributed compilation: compile tasks and their subprocesses are now aborted when a client
  disconnects, instead of running to completion on the build server (#​2761, #​2774). The
  ToolchainPackager cfg gate was fixed so the dist code builds on ppc64le and s390x (#​2749).
• S3 SSE-KMS: server-side encryption with KMS keys is now supported (#​2770).
• Diagnostics: gcc color diagnostics now behave the same way as rustc's (#​2758).
• Preprocessor correctness: -ivfsoverlay is treated as a preprocessor-only argument (#​2767).
