This mainly avoids protoc from 3.7.0 which has a dependency on libatomic. Most
of our systems have libatomic, so it mostly works, but the interop docker
container does not, so building fails. Version 3.7.1 was rebuilt to avoid
needing the libatomic shared library.
This has the added benefit that Bazel is now on the same version as Gradle, as
3.7.1 included fixes for Bazel.
For Bazel, we upgrade to protobuf 3.6.1.2 and javalite HEAD to fix
incompatibilities in newer Bazel releases.
compiler/Dockerfile is unused, so it was removed instead of being updated.
protoc no longer includes codegen for nano, so we remain on the older protoc
any time nano is used.
Protobuf now requires C++11 when compiling, so windows was swapped to
VC 14.
We always want to use a consistent version of protobuf; avoid the need
for the caller (which may be a person running the script) to specify the
version.
It doesn't appear that OS X is saving its cache yet, so this may not be
needed in the future, but for now we need OS X to avoid attempting to
use the Linux binaries.
The previous download link only worked for the most recent version. The
new form only works for old versions. That will encourage us not to use
the latest version, but for tests that's probably not a big deal.
We haven't noticed the breakage sooner because the build results are
cached.
