follow-up commit to https://gerrit.libreoffice.org/#/c/9226/ .
text_cat -s was documented as "Not very efficient yet, because
language models are re-loaded after each line." So if we want
to use text_cat -s for thousands of lines, better
read the language models only once and store them.
When tested on svl/source, the speed-up was a futher factor 1.5
(reduced from 6 s to 4 s).

Instead of recreating a text_cat sub-process for every string, start a
single text-cat process (with the -s flag, "per line") and reuse that.
Testing on svl/source shows a speed-up of 7.5 x, down from 45.6s to 6.1s!
To avoid blocking on the pipes set autoflush in text-cat, and use
read_line instead of read on the find-german-comments side.
