 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All

As per my notes on Bug 8437, starting at
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=8437#c33, any Koha
.pl script that needs to stream a large response to a client web browser is
never going to work, so long as we're using Plack::App::CGIBin to create a PSGI
handler. 

While I tried to create my own streaming version of Plack::App::WrapCGI, I
found a third-party module to be buggy, and that writing my own would be
prohibitive in terms of time and energy. It's also architectural glue code that
we really might not want to maintain long-term.

So I've concluded that an alternative would be to write a Mojolicious
controller to replace export.pl. While CGI Koha can still use export.pl, when
we're using Starman/Plack, we can redirect to the appropriate Mojolicious
endpoint.
