With some combinations of options tests for typeof, snprintf, and
vsnprintf end up with warnings promoted to errors, which then trigger
incorrect results for these tests. Move the typeof test to the end,
and write specific tests for snprintf and vsnprintf.

If the C compiler has typeof(), we can use a safer implementation of
the offsetin() macro by using typeof(). Since typeof() isn't standard
(yet?) autoconf has to test for it.

It is a bit confusing when the alloc_size attribute is tested for more
than once, to include the arguments in the output message.

Old versions of gcc didn't define either __GNUC_STDC_INLINE__ or
__GNUC_GNU_INLINE__, but imply the latter.

Separate out function and function pointer attributes, as not all
versions of all compilers support both.
Have macros related to function attributes auto-generated by
autoheader. As a result, rename config.h.in to unconfig.h, to make it
more obvious that it is really intended to be included from some C
programs.

The name "aux" is reserved on Windows platforms, a legacy from CP/M
via MS-DOS. Rename it to "helpers".
Turns out that that directory wasn't actually used properly, because
AC_CONFIG_AUX_DIR was never defined, and there was a redundant copy of
install-sh checked into the base of the source tree.
