The 1.x branch of Babeltrace has been superseded by 2.x in 2020 and has been unmaintained since 2022, efforts have started to remove it from popular distributions.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.
