We will attempt to generate Atom feeds "by hand" as the
XML::Atom::SimpleFeed API does not support streaming output.
Since email is large and servers are small, this should prevent
wasting memory when we generate larger feeds.

Of course, we hope clients use SAX parsers capable of handling
large streams without slurping.

v2: Removed unused attr escaping code in Hval

Since email is large and servers are small, this should prevent
wasting memory when we generate larger feeds.

Of course, we hope clients use SAX parsers capable of handling
large streams without slurping.
