* Add a new --configure_only option to build.py to allow build.py to generate a .bazelrc without necessarily building jaxlib.
* Add a bazel flag that make the dependency of //jax on //jaxlib optional. If //jaxlib isn't built by bazel, then tests will implicitly use a preinstalled jaxlib.
The `jax.experimental.stax` and `jax.experimental.optimizers` modules are standalone examples libraries. By contrast, the remaining modules in `jax.experimental` are experimental features of the JAX core system. This change moves the two example libraries, and the README that describes them, to `jax.example_libraries` to reflect this distinction.

* trailing-whitespace
* dangerous-default-value. None of these appear to be bugs in practice, but the potential for accidentally mutating the default value is there, and the cost of avoiding the problem is small.
* invalid-envvar-default. Pass strings as getenv() defaults.
* unnecessary-semicolon. Use tuples instead for this one-liner.
* invalid-hash-returned. Raise an exception rather than asserting false.
* pointless-string-statement. Use comments instead.
* unreachable. Use @unittest.skip() decorator rather than raising as first line in test.
* logging-not-lazy. Make the logging lazy.
* bad-format-string-type. Use f-string instead.
* subprocess-run-check. Pass check=...

The JAX operators:
jax.ops.index_update(x, jax.ops.index[idx], y)
jax.ops.index_add(x, jax.ops.index[idx], y)
...
have long been deprecated in lieu of their more succinct counterparts:
x.at[idx].set(y)
x.at[idx].add(y)
...
This change updates users of the deprecated APIs to use the current APIs, in preparation for removing the deprecated forms from JAX.
The main subtlety is that if `x` is not a JAX array, we must cast it to one using `jnp.asarray(x)` before using the new form, since `.at[...]` is only defined on JAX arrays.

* Avoid lexically capturing the train_images value in MNIST VAE example.
This has the effect of baking in the training dataset as a constant, something that LLVM does not like that much.
* Add device_put to images.
* fix jit in example
* Avoid using static_argnums on a keyword argument; use a positional argument and a wrapper function for now.
