Description

I read on http://redmine.lighttpd.net/projects/1/wiki/Mimetype_use-xattrDetails that lighttpd will look at a user-defined xattr value under the "Content-Type" key.

I recently saw similar functionality in Apache's "mod-mime-xattr", https://packages.debian.org/fr/sid/httpd/libapache2-mod-mime-xattr

The documentation for Apache's mime xattr references freedesktop.org specifications, which states that the "user.mime_type" key should be used: http://standards.freedesktop.org/shared-mime-info-spec/latest/ar01s02.html#idm140622087713936

I quote with lost formatting:
"Storing the MIME type using Extended Attributes
An implementation MAY also get a file's MIME type from the user.mime_type extended attribute. [...]"

So how about lighttpd starts using the freedesktop.org defined value (user.mime_type) and maybe just use Content-Type as fallback?

Perhaps a new config option mimetype.xattr-name could be used to specify the attribute name 

mimetype.xattr-name = "Content-Type"    /* default for lighttpd backward compatibility */
mimetype.xattr-name = "user.mime-type"  /* user-specified to match freedesktop spec */

I'd be tempted to make this T_CONFIG_SCOPE_SERVER rather than T_CONFIG_SCOPE_CONNECTION to avoid the marginal cost of config merging.

@stbuehler, would you accept such a patch?

I agree with T_CONFIG_SCOPE_SERVER; a lot of stat() calls are not made on the target file directly, and therefore it sounds wrong to make this dependent on path / filename extension conditionals.

I neglected to update the doc when adding the new directive. Would you add the following? Thanks.
