This patch adds a C11 status table to c-status.html.
I consulted n3220.pdf (M.4) and https://gcc.gnu.org/wiki/C11Status,
and checked that Implemented in Version is correct.
I've added links to proposals where it seemed relevant.
Also add a small note about C17.
W3 validated. Ok?

+GCC has support for ISO C11, the 2011 revision of the ISO C standard.
+This standard is substantially completely supported (but refer to
