this change was created in the same spirit of 505900f18f. because
we are deprecating the operator<< for vector and unorderd_map in
Seastar, some tests do not compile anymore if we disable these
operators. so to be prepared for the change disabling them, let's
include test/lib/test_utils.hh for accessing the printer dedicated
for Boost.test. and also '#include <fmt/ranges.h>' when necessary,
because, in order to format the ranges using {fmt}, we need to
use fmt/ranges.h.

before this change, we rely on the default-generated fmt::formatter
created from operator<<, but fmt v10 dropped the default-generated
formatter.
in this change, we include `fmt/ranges.h` and/or `fmt/std.h`
for formatting the container types, like vector, map
optional and variant using {fmt} instead of the homebrew
formatter based on operator<<.
with this change, the changes adding fmt::formatter and
the changes using ostream formatter explicitly, we are
allowed to drop `FMT_DEPRECATED_OSTREAM` macro.

get0() dates back from the days where Seastar futures carried tuples, and
get0() was a way to get the first (and usually only) element. Now
it's a distraction, and Seastar is likely to deprecate and remove it.
Replace with seastar::future::get(), which does the same thing.
Currently, when the test is executed too quickly, the timestamp
insterted into the 'my_table' table might be the same as the
timestamp used in the SELECT statement for comparison. However,
the statement only selects rows where the inserted timestamp
is strictly lower than current timestamp. As a result, when this
comparison fails, we may skip executing the following comparison,
which uses a user-defined function, due to which the statement
is supposed to fail with an error. Instead, the select statement
simply returns no rows and the test case fails.
To fix this, simply use the less or equal operator instead
of using the strictly less operator for comparing timestamps.

We have enabled the command line options without changing a
single line of code, we only had to replace old include
with scylla_test_case.hh.
Next step is to add x-log-compaction-groups options, which will
determine the number of compaction groups to be used by all
instantiations of replica::table.

Recently we noticed a regression where with certain versions of the fmt
library,
SELECT value FROM system.config WHERE name = 'experimental_features'
returns string numbers, like "5", instead of feature names like "raft".
It turns out that the fmt library keep changing their overload resolution
order when there are several ways to print something. For enum_option<T> we
happen to have to conflicting ways to print it:
1. We have an explicit operator<<.
2. We have an *implicit* convertor to the type held by T.
We were hoping that the operator<< always wins. But in fmt 8.1, there is
special logic that if the type is convertable to an int, this is used
before operator<<()! For experimental_features_t, the type held in it was
an old-style enum, so it is indeed convertible to int.
The solution I used in this patch is to replace the old-style enum
in experimental_features_t by the newer and more recommended "enum class",
which does not have an implicit conversion to int.
I could have fixed it in other ways, but it wouldn't have been much
prettier. For example, dropping the implicit convertor would require
us to change a bunch of switch() statements over enum_option (and
not just experimental_features_t, but other types of enum_option).
Going forward, all uses of enum_option should use "enum class", not
"enum". tri_mode_restriction_t was already using an enum class, and
now so does experimental_features_t. I changed the examples in the
comments to also use "enum class" instead of enum.
This patch also adds to the existing experimental_features test a
check that the feature names are words that are not numbers.

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.

user_defined_function_test fails sporadically in debug mode
due to lua timeout. Raise the timeout to avoid the failure, but
not so much that the test that expects timout becomes too slow.

Rather than asserting, as seen in #7977.
This shouldn't crash the server in production.
Add unit test that reproduces this scenario
and verifies the internal error exception.

Add new validate_with_error_position function
which returns -1 if data is a valid UTF-8 string
or otherwise a byte position of first invalid
character. The position is added to exception
messages of all UTF-8 parsing errors in Scylla.
validate_with_error_position is done in two
passes in order to preserve the same performance
in common case when the string is valid.
The goal is to forward-declare utils::multiprecision_int, something
beyond my capabilities for boost::multiprecision::cpp_int, to reduce
compile time bloat.
The patch is mostly search-and-replace, with a few casts added to
disambiguate conversions the compiler had trouble with.
With this patch lua nil values are mapped to CQL null values instead
of producing an error.

Different versions of boost have different rules for what conversions
from cpp_int to smaller intergers are allowed.
We already had a function that worked with all supported versions, but
it was not being use by lua.

1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
