Log Message:
lint: add option to accept C11 features

The list of available letters for the command line options gets shorter
and shorter.  Most of the interesting letters are already used for some
warning categories.  Curiously, -A, -W and -E were all still available.

The option -A nicely matches the intention of the option, which is to
allow a certain set of language features.  To keep the option available
for further extensions, define -Ac11 as the currently only valid option
of that kind.  This allows straight-forward extension for C17 and future
language standards, as well as independent feature-sets.  The options -W
and -E may someday complement the -A option, using the allow/warn/error
categories.
