Security issue fixed:
- CVE-2017-14226: WP1StylesListener.cpp, WP5StylesListener.cpp, and
WP42StylesListener.cpp in libwpd 0.10.1 mishandle iterators, which
allows remote attackers to cause a denial of service (heap-based buffer
over-read in the WPXTableList class in WPXTable.cpp). This vulnerability
can be triggered in LibreOffice before 5.3.7. It may lead to suffering a
remote attack against a LibreOffice application. (bnc#1058025)

Bugfixes:
- Fix various crashes, leaks and hangs when reading damaged files found by
oss-fuzz.
- Fix crash when NULL is passed as input stream.
- Use symbol visibility on Linux. The library only exports public
functions now.
- Avoid infinite loop. (libwpd#3)
- Remove bashism. (libwpd#5)
- Fix various crashes and hangs when reading broken files found with the
help of american-fuzzy-lop.
- Make --help output of all command line tools more help2man-friendly.
