These projects were tested and it was found that their use
of MSAN does not work on Ubuntu 20.04. Therefore their use of
MSAN is being disabled.

[infra][build] Set HOME=/root on GCB when doing fuzzer builds.
GCB passes HOME as env var to the docker container. It sets
HOME to /builder/home which is persisted accross builds.
This issue causes build breakages in
https://github.com/google/oss-fuzz/issues/6035
and possibly https://github.com/google/oss-fuzz/issues/5317.
Perhaps more insidiuosly it can cause fuzzers to be built with
the wrong instrumentation.
* [presubmit] Enforce language attribute in projectt.yaml to be always set.
* Update documentation, better presubmit check, new project template.
* add docstring to templates.py
* Add example values in the project.yaml template and remove python value for now
* Add "project: c++" to 256 projects
* format
* Add labels and selective_unpack sections to the presubmit check
* fix incorrect auto_ccs format in three projects
* fix nss emails after rebase
The OSS-Fuzz builder and runner images have libunwind. Since
the OSS-Fuzz runner images aren't actually used to run fuzzers on
ClusterFuzz and are just actually used for testing(!) this passed
CI before even though it failed immediately on ClusterFuzz.
I've tested that with this fix, the fuzzer works on ClusterFuzz.
