src: Removing all pre 2.x "Since" documentation annotations.

This does not make sense to keep in the public API surface
documentation. As we are heading towards a release of 2.0, this
represents a "reset" in public API, and older annotations only
serve to clutter the documentation with information that is not
relevant to the reader.

Everything which is public at the time of the 2.0 release can
be considered available "Since: 2.0" implicitly (as this is
going to be the starting point of this new stable API).

It will make sense to start adding these annotations again for any
added API in 2.2 and forward.
