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
Currently, if the data_size is greater than
max_chunk_size - sizeof(chunk), we end up
allocating up to max_chunk_size + sizeof(chunk) bytes,
exceeding buf.max_chunk_size().
This may lead to allocation failures, as seen in
https://github.com/scylladb/scylla/issues/7950,
where we couldn't allocate 131088 (= 128K + 16) bytes.
This change adjusted the expose max_chunk_size()
to be max_alloc_size (128KB) - sizeof(chunk)
so that the allocated chunks would normally be allocated
in 128KB chunks in the write() path.
Added a unit test - test_large_placeholder that
stresses the chunk allocation path from the
write_place_holder(size) entry point to make
sure it handles large chunk allocations correctly.

We use boost test logging primarily to generate nice XML xunit
files used in Jenkins. These XML files can be bloated
with messages from BOOST_TEST_MESSAGE(), hundreds of megabytes
of build archives, on every build.
Let's use seastar logger for test logging instead, reserving
the use of boost log facilities for boost test markup information.
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.
