test_distributed_loader_with_pending_delete issues a dma write, but violates
the unwritten contract to temporary_buffer::aligned(), which requires that
size be a multiple of alignment. As a result the test fails spuriously.
Instead of playing with the alignment, rewrite that snippet to use the
easier-to-use make_file_output_stream().
Introduced in 1ba88b709f.

tmpdir is a helper class representing a temporary directory.
Unfortunately, it suffers for some problems such as lack of proper
encapsulation and weak typing. This has caused bugs in the past when the
user code accidentally modified the member variable with the path to the
directory.
This patch modernises tmpdir and updates its users. The path is stored
in a std::filesystem::path and available read-only to the class users.
mkdtemp and boost are replaced by standard solution.
The users are update to use path more (when it didn't involve too many
changes to their code) and stop using lw_shared_ptr to store the tmpdir
when it wasn't necessary.
tmpdir intentionally doesn't provide any helpers for getting the path as
a string in order to discourage weak types.

Switch to the the CMake-ified Seastar
This change allows Scylla to be compiled against the `master` branch of
Seastar.
The necessary changes:
- Add `-Wno-error` to prevent a Seastar warning from terminating the
build
- The new Seastar build system generates the pkg-config files (for
example, `seastar.pc`) at configure time, so we don't need to invoke
Ninja to generate them
- The `-march` argument is no longer inherited from Seastar (correctly),
so it needs to be provided independently
- Define `SEASTAR_TESTING_MAIN` so that the definition of an entry
point is included for all unit test compilation units
- Independently link Scylla against Seastar's compiled copy of fmt in
its build directory
- All test files use the (now public) Seastar testing headers
- Add some missing Seastar headers to source files
[avi: regenerate frozen toolchain, adjust seastar submoule]

Test removal of sstables with temporary TOC file,
with and without temporary sstable directory.
Temporary sstable directories may be empty or still have
leftover components in them.

Replace stdx::optional and stdx::string_view with the C++ std
counterparts.
Some instances of boost::variant were also replaced with std::variant,
namely those that called seastar::visit.
Scylla now requires GCC 8 to compile.

sprint() recently became more strict, throwing on sprint("%s", 5). Replace
with the more modern format().
Mechanically converted with https://github.com/avikivity/unsprint.
Introduce class result_options to carry result options through the
request pipeline, which at this point mean the result type and the
digest algorithm. This class allows us to encapsulate the concrete
digest algorithm to use.

We may want to change the default individual result size limit in the
future. If it is provided by the coordinator and not hardcoded in the
replicas this can be done without causing data query digest mismatches
or wasteful mutation query results.
This patch makes the optional trace_state_ptr arguments introduced in
previous patches mandatory where possible. Functions which are called
internally don't have a trace context, so for those we keep the
argument's default value for convenience.
