this is a part of a series to migrating from `operator<<(ostream&, ..)`
based formatting to fmtlib based formatting. the goal here is to enable
fmtlib to print UUID without using ostream<<. also, this change reimplements
some formatting helpers using fmtlib for better performance and less
dependencies on operator<<(), but we cannot drop it at this moment,
as quite a few caller sites are still using operator<<(ostream&, const UUID&)
and operator<<(ostream&, tagged_uuid<T>&). we will address them separately.
* add fmt::formatter<UUID>
* add fmt::formatter<tagged_uuid<T>>
* implement UUID::to_string() using fmt::to_string()
* implement operator<<(std::ostream&, const UUID&) with fmt::print(),
this should help to improve the performance when printing uuid, as
fmt::print() does not materialize a string when printing the uuid.

* throw marshal_exception if not the whole string is parsed, we
should error out if the parsed string contains gabage at the end.
before this change, we silent accept uuid like
"ce84997b-6ea2-4468-9f02-8a65abf4wxyz", and parses it as
"ce84997b-6ea2-4468-9f02-8a65abf4". this is not correct.
* throw marshal_exception if stoull() throws,
`stoull()` throws if it fails to parse a string to an unsigned long
long, we should translate the exception to `marshal_exception`, so
we can handle these exception in a consistent manner.
test is updated accordingly.

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.

sprint() recently became more strict, throwing on sprint("%s", 5). Replace
with the more modern format().
