Log Message:
lint: in C99 mode, make implicit function declarations an error

In tree.c 1.294 from 2021-06-28, I had already tried this, but at that
time, there were too many implicit function definitions in the NetBSD
tree.  Most of them were GCC builtins, which lint did not recognize.
Therefore I had to revert to a warning in tree.c 1.302 from 2021-06-30.

In the meantime, lint has learnt to recognize compiler builtins, see
is_compiler_builtin, so try again now.  The build logs from x86_64,
i386, sparc and sparc64 show no more implicit function declarations.
