clonebundles: adds a auto-generate.serve-inline option This new option disable the "external" serving of auto generated bundle in favor of using the new "inline bundle" feature that allow serving such bundle through the mercurial protocol. This is a less efficient, but very easy to setup way to start using clone bundle.

"""
List-valued configuration keys have an ad-hoc microsyntax. From `hg help config`:

> List values are separated by whitespace or comma, except when values are
> placed in double quotation marks:
>
>     allow_read = "John Doe, PhD", brian, betty
>
> Quotation marks can be escaped by prefixing them with a backslash. Only
> quotation marks at the beginning of a word is counted as a quotation
> (e.g., ``foo"bar baz`` is the list of ``foo"bar`` and ``baz``).

That help documentation is fairly light on details, the actual parser has many
other edge cases. This test tries to cover them.
