Update to 5.4.6. JB#57054

[pvuorela]

Two commits, first updating to 5.4.4:

- Deleted non-sailfish history, had some bogus dates and it's not ours.
- The rpm conflicts should be now better when the rpm and rpm-libs are
merged. Presumably compat module no longer needed.
- Autotoolize patch updated to skip removed bitlib file.

Attempted git submodule based packaging too, but that seemed problematic.
It doesn't fully match .tar.gz content. Different (non non-working)
makefile, lacking luac.c, missing even install: rule on the makefile.

Second commit adding the patches fedora includes, almost all from git. Except that despite fedora listing github urls for them, actually they aren't verbatim. The patches do include change on tests but those are in different tar ball and different path as what the git version has.

I hereby declare lua a sucky project and all the related distro packagings too. Building, and patching and everything is a mess here.

New releases since so bumped to latest version. Allowed to delete quite a bunch of patches. Fedora has now one upstream bug cherry-picked. No idea if there are good reasons for us, but for simplicity didn't do it now. The fixed function doesn't appear touched in years before it, so this shouldn't at least be worse than the previous update candidate here.
