* [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
* Add fuzzer for mpg123_decode.
This fuzzes a different and non-filebased API that read_fuzzer.c.
mpg123_decode is, however, streaming based so we need to chunk the
fuzzer's input into multiple pieces, and pass them to the library. This
is pretty annoying to do by hand so I've introduced byte_stream.h to do
this automatically. Sadly, byte_stream.h is very C++ so the
decode_fuzzer is also C++ now. This isn't ideal since mpg123 is a
C library but this is the easiest way to do it.
* Do not carry next input within std::string.
* Malloc a new buffer for each decode invocation.
I used malloc instead of new since ideally this fuzz target would be
written in C.
