some of these helpers prints a byte array using `to_hex()`, which
materializes a string instance and then drop it on the floor after
printing it to the given ostream. this hurts the performance, so
`fmt::print()` should be more performant in comparison to the
implementations based on `to_hex()`.

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
By default {fmt} doesn't know how to format this type (although it's a
basic_string_view instantiated), and even providing formatter/operator<<
does not help -- it anyway hits an earlier assertion in args mapper about
the disallowance of character types mixing.
The hex-wrapper with own operator<< solves the problem.

This is just a trivial wrapper over initialized_later when using
sstring, but also works when std::string is used.

"
Update Seastar `#include`s to reflect restructure
All Seastar header files are now prefixed with "seastar" and the
configure script reflects the new locations of files.

sprint() recently became more strict, throwing on sprint("%s", 5). Replace
with the more modern format().
Mechanically converted with https://github.com/avikivity/unsprint.
Some tests (eg murmur_hash_test) need only byte manipulation
functions. By specifying dependencies precisely we can drastically
reduce recompilation times, which speeds up development cycle.
I managed to reduce recompilation time for murmur_hash_test from 5
minutes to 4 seconds by breaking dependency on whole urchin object
set.
