gitweb: add $prevent_xss option to prevent XSS by repository content
Add a gitweb configuration variable $prevent_xss that disables features to prevent content in repositories from launching cross-site scripting (XSS) attacks in the gitweb domain. Currently, this option makes gitweb ignore README.html (a better solution may be worked out in the future) and serve a blob_plain file of an untrusted type with "Content-Disposition: attachment", which tells the browser not to show the file at its original URL. The XSS prevention is currently off by default. Signed-off-by: Matt McCutchen <matt@mattmccutchen.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
