[pve-devel] [PATCH http-server 1/2] allow 'download' to be passed from API handler

[Stefan Reiter <s.reiter@proxmox.com>]

PVE::HTTPServer in pve-manager wraps the API return value in a 'data'
element, look for a 'download' element there too to allow an API call to
instruct the HTTP server to return a file via path or filehandle.

This will be needed for the single file restore API.
