feat:$xhr: provide access to $xhr header defaults

$xhr header defaults are now exposed as $xhr.defaults.headers.common and
$xhr.default.headers.<httpmethod>. This allows applications to configure
their defaults as needed.

This commit doesn't allow headers to be set per request, only per
application. Per request change would require api change, which I tried
to avoid *for now*.
