Bugfix: Missing validation of invalid, embedded content in richtext in HeadlessServer

Richtext transformation did not filter invalid, embedded content links. The problem was fixed invoking the filter predicates during richtext transformation.

The changes made new constructors in the public API necessary. For backward compatibility, the former constructors were kept in the code as legacy constructors but marked deprecated for removal. It is highly recommended not to use the deprecated constructor anymore and instead update existing custom code to use the new constructors. Also be aware, using the old constructors will work but will also keep the old, wrong behavior!

HtmlFragment did not support data.sizeLong

A query for property sizeLong of data from a CMHTML document lead to an error, this is fixed now by adding the corresponding method ContentMarkupAdapter#getSizeLong. The method ContentMarkupAdapter#getSize is deprecated analog to ContentBlobAdapter#getSize.

Warning for cache configuration of Remote Links cache

The cache configuration for "remote-links" was erroneously configured with a specific weigher which lead to a warning. The cache is now configured without a specific weigher.
