9086988ffa Enforce maximum length of fuzz input 
Remove the libfuzzer max_len option which doesn't apply to other
fuzzing engines. Enforce the maximum length directly in the fuzz
targets. For the xml target, lower the maximum when expanding entities
to avoid timeout and OOM errors.

00ed736eec Add a couple of libFuzzer targets 
- 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.
