Khaled Hosny 5898a9618c [ragel] Regenerate state machine files with 6.10 2021-09-14 18:46:33 -06:00
Khaled Hosny 7e9ac8fea2 [meson] Require ragel 6.10 
Ragel 7 is also not stable from upstream's point of view.

This uses “version” argument find_program(), which was introduced in
meson 0.52.0, so I raised the minimum required meson version
accordingly.
