Add "strncmp() on string prefix" to
Documentation/process/deprecated.rst since using strncmp()
to check whether a string starts with a prefix is error-prone.
The safe replacement is str_has_prefix().
Also add check to the newly introduced deprecated_string_apis
in checkpatch.pl.

I skimmed this and a couple things jumped out at me.
1) PGP and S/MIME because of their use of long term keys do not provide
forward secrecy. Which can makes it worth while to cryptographically
factor a key or to obtain knowledge of a private key without the key
holders knowledge. As
