[Distutils] Simplify 426: Deprecate Author-email and Maintainer-email

[Daniel Holth]

I would prefer to see PEP 390 withdrawn and I think this has been
suggested before. The metadata is already sourced from different files
depending on your build system.

The .ini format and our parsers for it are really awful. I always
resented having to learn it in order to use distutils/setuptools when
every other language (RFC822, Python, JSON) is both better and already
familiar.

FWIW bdist_wheel does something half-PEP-390 inspired with setup.cfg:

[metadata]
provides-extra =
    tool
    signatures
    faster-signatures
requires-dist =
    distribute (>= 0.6.34)
    argparse; python_version == '2.6'
    keyring; extra == 'signatures'
    dirspec; sys.platform != 'win32' and extra == 'signatures'
    ed25519ll; extra == 'faster-signatures'
license-file = LICENSE.txt
