Revert "eina: add functions to alloc strings from a printf fmt"

This reverts commit b5fce696c7 and fixes
to NEWS and @since that came later.

These functions are pretty trivial and their functionality can be
obtained with asprintf() and snprintf. The first is not available only
on windows, but there's an implementation for that one on Evil, that
should be used instead.
