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
This adds a "--build-mode" command line option to "scylla" executable:
$ ./build/dev/scylla --build-mode
dev
This allows you to discover the build mode of a "scylla" executable
without resorting to "readelf", for example, to verify that you are
looking at the correct executable while debugging packaging issues.
Closes#7865
This adds version number generation in the build system. Version numbers
follow the format:
<version>-<release>
where release consists of:
<date>-<git-hash>
The version and release numbers are generated by the SCYLLA-VERSION-GEN
script and they are stored in SCYLLA-VERSION-FILE and
SCYLLA-RELEASE-FILE files so that other parts of the build system can
easily pick them up.
For builds that happen from release tarballs, for example,
SCYLLA-VERSION-GEN looks for a "version" file in the tree and just uses
that.
Basically, we're doing pretty much the same as Git is doing in its build
system.
