[Libreoffice] [PATCH] speed up localized builds by introducing po2lo

Hi,
We discussed with Andras that one of the bottleneck of a build with many
languages is the slowness of the po2oo script from translations-toolkit.
I gave it a try to rewrite it as a standalone script, and it seems to be
quite fast here:
$ time po2oo --skipsource -i hu/ -o hu.sdf -l hu -t en-US.sdf > hu.sdf
real 0m32.842s
user 0m29.205s
sys 0m1.439s
$ time ./po2lo --skipsource -i hu/ -o hu.sdf -l hu -t en-US.sdf > hu.sdf
real 0m3.756s
user 0m3.344s
sys 0m0.143s
The localized sdf file differs, but once you sort its contents, it's the
same for me.
Note that this does not remove the dependency on translations-toolkit:
the oo2po script is still used (but that's not invoked during a normal
build).
I'm attaching two patches:
- one for core.git, which adds the new po2lo script (localize was
already in solenv/bin, so I pot this one there as well).
- one for translations.git to actually use the new script: here I took a
look at how python is invoked in filters and did the same.
Andras, could you please give it some testing? I didn't want to push it
without your review, just in case I missed something. :)
Thanks,
Miklos
