framework: avoid -Werror=deprecated-copy (GCC trunk towards GCC 9)

...by removing explicitly user-provided functions that do the same as their
implicitly-defined counterparts, but may prevent implicitly declared copy
functions from being defined as non-deleted in the future.  (Even if such a
user-provided function was declared non-inline in an include file, the
apparently-used implicitly-defined copy functions are already inline, so why
bother with non-inline functions.)
