fuzz: new fuzzer for cext/manifest.c This is a bit messy, because lazymanifest is tightly coupled to the cpython API for performance reasons. As a result, we have to build a whole Python without pymalloc (so ASAN can help us out) and link against that. Then we have to use an embedded Python interpreter. We could manually drive the lazymanifest in C from that point, but experimentally just using PyEval_EvalCode isn't really any slower so we may as well do that and write the innermost guts of the fuzzer in Python. Leak detection is currently disabled for this fuzzer because there are a few global-lifetime things in our extensions that we more or less intentionally leak and I didn't want to take the detour to work around that for now. This should not be pushed to our repo until https://github.com/google/oss-fuzz/pull/1853 is merged, as this depends on having the Python tarball around.

Test chains of near empty directories, terminating 3 different ways:
- a1: file at level 4 (deepest)
- b1: two dirs at level 3
- d1: file at level 2

Set up the repo

  $ hg init test
  $ cd test
  $ mkdir -p a1/a2/a3/a4
  $ mkdir -p b1/b2/b3/b4
  $ mkdir -p b1/b2/b3/c4
  $ mkdir -p d1/d2/d3/d4
  $ echo foo > a1/a2/a3/a4/foo
  $ echo foo > b1/b2/b3/b4/foo
  $ echo foo > b1/b2/b3/c4/foo
  $ echo foo > d1/d2/d3/d4/foo
  $ echo foo > d1/d2/foo
  $ hg ci -Ama

  adding b1/b2/b3/b4/foo
  adding b1/b2/b3/c4/foo
  adding d1/d2/d3/d4/foo
  adding d1/d2/foo
  $ hg serve -n test -p $HGPORT -d --pid-file=hg.pid -E errors.log
  $ cat hg.pid >> $DAEMON_PIDS
