Fix format security errors with hardening build flags

These problems were found while building with the hardening options used
by Debian. In order to prevent introducing new unsafe constructs, the
options -Wformat" and -Werror=format-security are addeded to the CFLAGS
by configure.ac if the compiler supports them.

Also, a small spelling fix in posix-aio.c is included.
