Miklos Vajna 8ad82fc115 sw floattable: fix nullptr deref in TableManager::endLevel() 
This is never an empty reference in the interesting use-case, so just
make sure we don't crash.

Reported to be a regression from
2d43c34333 (Related: tdf#55160 sw
floattable, nested DOCX imp: fix inner tbl at cell start, 2023-09-15).

Import Filters for LibreOffice Writer

The writerfilter module contains import filters for Writer, using its UNO API.

Import filter for DOCX and RTF.

  • Module contents

    • documentation: RNG schema for the OOXML tokenizer, etc.
    • inc: module-global headers (can be included by any files under source)
    • qa: cppunit tests
    • source: the filters themselves
    • util: UNO passive registration config

  • Source contents

    • dmapper: the domain mapper, hiding UNO from the tokenizers, used by DOCX and RTF import
      • The incoming traffic of dmapper can be dumped into an XML file in /tmp in dbgutil builds, start soffice with the SW_DEBUG_WRITERFILTER=1 environment variable if you want that.
    • filter: the UNO filter service implementations, invoked by UNO and calling the dmapper + one of the tokenizers
    • ooxml: the docx tokenizer
    • rtftok: the rtf tokenizer
