Bump crengine:
- Ensure text decoration (underline) is continued over word gaps
- Invalidate TOC page numbers on rendering change
- Ensure reproducible cache files when same rendering settings
- LVBlockWriteStream: workaround to exclude fatal error
- Use utf8proc for string uppercase/lowercase/capitalize
Bump base:
Thirdparty: adds utf8proc 2.3.0 (libutf8proc.so.2)
For use by crengine, for now mostly for more complete and
accurate text-transform: uppercase/lowercase/capitalize.
Also revert test tweak (in 27ddd6f) to workaround an issue with
cre cache that should be solved by this crengine bump.
