This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).

# Fixed URLs

## Fixed But Review Recommended
These URLs were fixed, but the https status was not OK. However, the https status was the same as the http request or http redirected to an https URL, so they were migrated. Your review is recommended.

Prior to this commit, the various `HttpMessageConverter` instances
configured for a given `RestTemplate` instance could all contribute
`MediaType` values to the "Accept:" request header.

This could lead to duplicate media types in that request header,
cluttering for the HTTP request for no reason.

This commit ensures that only distinct values are added to the request.

(cherry picked from commit 31a24720)

The xml parser does not fill in defaults provided in the XSD when
validation is disabled. As a result, attributes like default-lazy-init
will not receive the value "default" but an empty string.

With this commit, BeanDefinitionParserDelegate now takes this into
account, checking default values against empty string as well as
"default".

As a consequence, default-lazy-init attribute should now work correctly
even when the XSD validation is disabled.
