Packaging: merge libreoffice-l10n into libreoffice

[Olivier Tilloy]

Many years ago, the libreoffice Ubuntu packages were split into two source packages: libreoffice and libreoffice-l10n. This was due to launchpad builders running out of disk space during the build. It looks like this limitation might no longer be relevant, from a conversation I had with launchpad folks on IRC:

<oSoMoN> how much disk space do builders have at their disposal when building debs?
<wgrant> oSoMoN: The instances have 60GB root volumes, and all but a couple of gigabytes should be usable by the build
<oSoMoN> wgrant, thanks! was this increased in the last few years by any chance? I'm asking because the libreoffice package was artificially separated into two source packages because of a disk space limitation, and I'm wondering whether we could get rid of this workaround now
<oSoMoN> 60GB should be enough for that purpose
<oSoMoN> but I'd like to understand what the limitation was previously
<wgrant> oSoMoN: It's slowly increased over the years. The -l10n split was back in the Xen days.
<wgrant> I really don't remember what things were set to back then
<wgrant> Probably 40GB, but not sure
<wgrant> oSoMoN: Hmm, the split actually predates virtualised builders at all, so there's really no way to tell unless you can find IRC logs from 12 years ago
<oSoMoN> wgrant, ack, in any case it looks like it's worth trying to reconcile the two source packages now, there's a good chance it will work
<wgrant> oSoMoN: Worth a try indeed
<cjwatson> Until a few years ago builders weren't particularly clean, either.
<oSoMoN> cjwatson, so less disk space available due to leftovers?
<cjwatson> Certainly in the pre-virtualised days you could very well end up with piles of junk left around from old kernels, previous builds, etc.
<cjwatson> And it wouldn't have been consistent across builders.
