now that we are allowed to use C++23. we now have the luxury of using
`std::views::reverse`.
- replace `boost::adaptors::transformed` with `std::views::transform`
- remove unused `#include <boost/range/adaptor/reversed.hpp>`
this change is part of our ongoing effort to modernize our codebase
and reduce external dependencies where possible.

dynamic_bitset allocates only when constructed.
then on it doesn't throw.
Though not that accessing bits out of range
is undefined behavior.

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
They are no longer used, and cannot be efficiently implemenented
for large bitsets using a summary vector approach without slowing
down the find_*_set() variants, which are used.
Also remove find_previous_set() for the same reason.
- introcduced "seastarx.hh" header, which does a "using namespace seastar";
- 'net' namespace conflicts with seastar::net, renamed to 'netw'.
- 'transport' namespace conflicts with seastar::transport, renamed to
cql_transport.
- "logger" global variables now conflict with logger global type, renamed
to xlogger.
- other minor changes
A dynamic bitset implementation that provides functions to search for
both set and cleared bits in both directions.
