Create a really simple Amazon S3 REST client
This is a very basic client for Amazon's Simple Storage Service (S3).
The client is able to perform the basic FTP like operations necessary
to support storing a Git repository on the S3 servers, assuming the
transport is implemented as a dumb protocol style transport similar
to the existing sftp:// transport.
A tiny command line client is included to facilitate manual testing
against the S3 servers, as well as emergency operations such as
getting content or deleting content.
