XIncludes involve XPath processing which can still lead to timeouts when
fuzzing. This will probably take a while to fix. The rest of the XML
parsing code should hopefully run without timeouts now. OSS-Fuzz only
shows a single timeout test case, so separate the XInclude from the core
XML fuzzer.
- XML fuzzer
Currently tests the pull parser, push parser and reader, as well as
serialization. Supports splitting fuzz data into multiple documents
for things like external DTDs or entities. The seed corpus is built
from parts of the test suite.
- Regexp fuzzer
Seed corpus was statically generated from test suite.
- URI fuzzer
Tests parsing and most other functions from uri.c.
