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

# Called by configure.py to merge several compdbs into one, so your
|
|
# favourite compatible code indexer can present you with a relevant
|
|
# maximally-complete unified index.
|
|
#
|
|
|
|
# Usage: merge-compdb.py build/{debug,release,dev,sanitize} [input...]
|
|
#
|
|
# Glue inputs, which must be compdb ("compile_command.json") files,
|
|
# together, filtering out anything that is not indexable or not built
|
|
# under the given prefix, and write the result to stdout.
|
|
#
|
|
# An input is either a file name or "-" for stdin.
|
|
#
|
|
# configure.py calls this with "-" for the ninja-generated scylla
|
|
# compdb and mode-specific seastar & abseil compdbs.
