Extend HAVE_C99_MATH checks in CMakeLists.txt and configure.ac to
include test for C99 function isnan.

but I doubt this will fix the build failures on the CI machines.

Set flags for Intel compiler to prevent incorrect optimization of
arithmetic expressions #826. Guard against nans in sincosdx #834.
Issue #831 is not addressed here (need more information...).

Fixes: #759

Make sure that the gie files in test/gie and test/gigs are included
in the distribution tarball. Tests with gie are set up to run all
available files matching *.gie in the gie and gigs directories. For
this reason tests that are known to fail in gigs/ have been renamed
to *.gie_failing, so that "make check" can be run in-tree in local
copies of the git repository.

This tests whether the functions are declared in <math.h>. If they are,
then -DHAVE_C99_MATH=1 is added to the C flags. The intention is that
this flag is only seen when building proj.4 and shouldn't be referenced
in any of the installed include files. The next update to geodesic.c
will use this flag.
Left unaddressed is what to do if HAVE_C99_MATH is 0. The strategy in
geodesic.c is to assume that the missing functions will need to be
defined explicitly. A less safe alternative is to assume that the
functions are in fact available in libm and that all that needs to be
done is to declare the functions.

* upgrade geodesic.[ch3]
* add test suite geodtest.c and invoke via cmake's add_test
* increment version to 4.9.3 and library version to 11.0.0

On my system (Ubuntu 10.04), ./autogen.sh doesn't copy config.guess
and config.sub, which cause ./configure to fail

This setting does not help anything.
