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
Currently, replace and bootstrap share the same streaming reason,
stream_reason::bootstrap, because they share most of the code
in boot_strapper.
In order to distinguish the two, we need to introduce a new stream
reason, stream_reason::replace. It is safe to do so in a mixed cluster
because current code only check if the stream_reason is
stream_reason::repair.

In case of error on the sender side, the sender does not propagate the
error to the receiver. The sender will close the stream. As a result,
the receiver will get nullopt from the source in
get_next_mutation_fragment and pass mutation_fragment_opt with no value
to the generating_reader. In turn, the generating_reader generates end
of stream. However, the last element that the generating_reader has
generated can be any type of mutation_fragment. This makes the sstable
that consumes the generating_reader violates the mutation_fragment
stream rule.
To fix, we need to propagate the error. However RPC streaming does not
support propagate the error in the framework. User has to send an error
code explicitly.
Fixes: #4789
On receiving a mutation_fragment or a mutation triggered by a streaming
operation, we pass an enum stream_reason to notify the receiver what
the streaming is used for. So the receiver can decide further operation,
e.g., send view updates, beyond applying the streaming data on disk.
Fixes#3276

Wrapping ranges are a pain, so we are moving wrap handling to the edges.
Since cql can't generate wrapping ranges, this means thrift and the ring
maintenance code; also range->ring transformations need to merge the first
and last ranges.

There are only two messages: prepare_message and outgoing_file_message.
Actually only the prepare_message is the message we send on wire.
Flatten the namespace.
