* 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=...

Most of the work here is porting the LAPACK interface from Cython to plain C++. This is something I wanted to do anyway to make use of C++ templating facilities: the code is noticeably shorter in C++.
This change removes the only use of Cython in JAX. It also removes the need for a build-time dependency on Scipy, which we only needed for Cython cimport reasons.
When using C++, we most likely do not want to fetch LAPACK and BLAS kernels from Python. Therefore we add another option: we define the LAPACK functions we need using weak symbols where supported; the user can then simply link against LAPACK to provide the necessary symbols.
Added a jaxlib:cpu_kernels module to facilitate using the JAX CPU kernels from C++.

Resolution order of paths to bazel binary is as follows.
1. Use --bazel_path command line option.
2. Search bazel binary in PATH environment variable.
3. Download required bazel release.
1. Build on Windows
2. Fix OverflowError
When calling `key = random.PRNGKey(0)` OverflowError: Python int too
large to convert to C long for casting value 4294967295 (0xFFFFFFFF)
from python int to int32.
3. fix file path in regex of errors_test
4. handle ValueError of os.path.commonpath
Changes:
- Fix unnecessary generator
- Iterate dictionary directly instead of calling .keys()
- Remove global statement at the module level
- Use list() instead of a list comprehension
- Use with statement to open the file
- Merge isinstance calls
* Use dynamic loading to locate CUDA libraries in jaxlib.
This should allow jaxlib CUDA wheels to be manylinux2010 compliant.
* Tag CUDA jaxlib wheels as manylinux2010.
Drop support for CUDA 9.2, add support for CUDA 11.0.
* Reorder CUDA imports.
