buf

• Fix: use -c on git parent command instead of --config on git fetch.
• Add ruby_package to managed mode.

• Add buf export. buf export will export the files from the specified input (default ".") to the given directory in a manner that is buildable by protoc without any -I flags. It also has options --exclude-imports, which excludes imports (and won't result in a buildable set of files), and --path, which filters to the specific paths.

• Rewrite the git cloner to use git init && git fetch rather than git clone. git clone is limited to local branches on the remote, whereas git fetch we can fetch any references on the remote including remote branches.
• Add php_namespace managed mode handling.
• Add java_string_check_utf8 managed mode handling.

• Add buf login and buf logout to login and logout from the Buf Schema Registry.
• Fix cache, configuration, and data environment variables for Windows. Note that while Windows is still not officially supported, buf largely works on Windows.

• Revert default configuration file location back from buf.mod to buf.yaml. Note that both continue to work.
• Move default workspace configuration file location from buf.work to buf.work.yaml. Note that both continue to work.
• Move buf beta push to buf push. Note that buf beta push continues to work.
• Move most buf beta mod commands to buf mod. Note that all buf beta mod commands continue to work.

• Fix issue where C++ scoping rules were not properly enforced.

• Change the default module configuration location from buf.yaml to buf.mod. Note that buf.yaml continues to work.
• Continued work on the workspaces beta, including the v1 configuration specification.

• Update the tested protoc version for compatibility to 3.15.2. The --experimental_allow_proto3_optional flag is no longer set for versions >=3.15.
