context: stop catching RepoLookupError from namespace.singlenode()
As pointed out by Yuya, the RepoLookupError was there for catching
errors from repo.branchtip(). However, since 885c0290f7d5 (localrepo:
add ignoremissing parameter to branchtip, 2014-10-16), that should no
longer happen. I think it should now be an error if a namespace raises
a RepoLookupError, so we propagate the exception up and and make it
easy to fix, rather than trying to interpret the changeid as nodeid
prefix and raise a general "unknown revision '...'" error.
I also don't think we should catch FilteredLookupError and LookupError
from the changelog.rev() call, for the same reason as above: If a
namespace returns a node that doesn't exist, we should provide a more
helpful exception than "unknown revision '...'".

How to add fuzzers (partially cribbed from oss-fuzz[0]): 1) git clone https://github.com/google/oss-fuzz 2) cd oss-fuzz 3) python infra/helper.py build_image mercurial 4) docker run --cap-add=SYS_PTRACE -it -v $HG_REPO_PATH:/hg-new \ gcr.io/oss-fuzz/mercurial bash 5) cd /src 6) rm -r mercurial 7) ln -s /hg-new mercurial 8) cd mercurial 9) compile 10) ls $OUT Step 9 is literally running the command "compile", which is part of the docker container. Once you have that working, you can build the fuzzers like this (in the oss-fuzz repo): python infra/helper.py build_fuzzers --sanitizer address mercurial $HG_REPO_PATH (you can also say "memory", "undefined" or "coverage" for sanitizer). Then run the built fuzzers like this: python infra/helper.py run_fuzzer mercurial -- $FUZZER 0: https://github.com/google/oss-fuzz/blob/master/docs/new_project_guide.md
