In the new API the biggest change is to implement the only
data_sink_impl::put(span<temporary_buffer>) overload.
Encrypted file impl and sstables compress sink use fallback_put() helper
that generates a chain of continuations each holding a buffer.
The counting_data_sink in transport had mostly been patched to correct
implementation by the previous patch, the change here is to replace
vector argument with span one.
Most other sinks just re-implement their put(vector<temporary_buffer>)
overload by iterating over span and non-preemptively grabbing buffers
from it.

It's going to be removed by next-after-next patch, but the next one
needs this overload implemented properly, so here it is.

They don't need to modify the captured objects. In fact, they must not
do it in the first place, because the request can be called more than
once and the buffers must not change between those invocations.
For the memory_sink_buffers there must be const method to get the vector
of temporary_buffers themselves.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
