Remove the Bazel mirror URL that we use in our WORKSPACE file

This doesn't appear to be supported. We use --distdir caching in our tests.

e1f6f54830c415fc8bb8dc14483fae4cf9713d75 by Abseil Team <absl-team@google.com>:

Removing comments following license() rules as they are rarely useful, redundant with LICENSE files, and tend to fall out of date.

b59c076638a57a74a3f8475f1dee8b536e32a15f by Gennadiy Rozental <rogeeff@google.com>:

Change GetAllFlags API to return a collection of mutable flag handles.

This will make this interface on par with FindCommandLineFlag and allow to call
CommandLineFlag::ParseFrom on the handle returned by GetAllFlags.

Make raw_hash_set compile when AllocTraits::propagate_on_container_swap is false.

837f62c85ea65c1d6b847a75816198c625fe62ff by Abseil Team <absl-team@google.com>:

On macOS, `mem_alloc` is defined like this:

rpc/types.h:86:#define mem_alloc(bsize)	calloc(1, bsize)

So if that file is included before container_memory.h, the variable mem_alloc
may never get defined. This is fixed by using a different name.
