Prepare for external Bazel change --incompatible_load_java_rules_from_bzl.

...by load()-ing java_library and other rules wherever we use them.

Compare to CL 297412705 for Flogger.

This CL includes updating to a new version of bazel_common to avoid --incompatible_load_java_rules_from_bzl errors in bazel_common. See https://github.com/google/bazel-common/pull/104.

Note that this CL also changes the way we get zlib() (a dependency of protobuf) from bind() to http_archive().
http_archive() seems to be the more recommended pattern:
- https://docs.bazel.build/versions/master/external.html#repository-rules
- https://github.com/bazelbuild/bazel/issues/1952
But my immediate motivation was that bind() wasn't working with the new version of protobuf. (The new version of protobuf is necessary to avoid --incompatible_load_java_rules_from_bzl errors inside protobuf. It comes with the new version of bazel_common.)
