rename tools/build/feature/{test-libbabeltrace.c => test-babeltrace2-ctf-writer.c} (59%)
The 1.x branch of Babeltrace has been superseded by 2.x in 2020 and has
been unmaintained since 2022, efforts have started to remove it from
popular distributions.
Babeltrace 2.x offers a very similar 'ctf-writer' library that can be used
with minimal changes for the '--to-ctf' feature and has been packaged
since Debian 11 and Fedora 32.
This patch replaces the 'libbabeltrace' build feature with
'babeltrace2-ctf-writer' using pkgconfig detection, adjusts the naming of
the public headers and applies minor API cleanups.
There is no changes to the output ctf traces, the ctf-writer API still
implements version 1.8 of the CTF specification that can be read by
either Babeltrace 1 / 2 or any CTF compliant reader.
Also remove some ifdefs in the cli option parsing to allow printing the
helpful error message with '--to-ctf' when built without babeltrace2.
