Functional programming with GLib

Hi All,

A while back, I wrote some functions for functional-flavored programming
with GLib. It's fully documented[1], has tests, etc.

It would (for me at least) be useful to have some of these functions in
GLib-proper, but I suspect the GLib-maintainers are not /too/ eager to
accept contributions to GList... anyway, perhaps its useful for others.

As a simple example, suppose we want to calculate the sum of primes up
to 100 (a common task after all):

| int    sum;
| GList *nums, *primes;
| nums   = gx_list_iota (100, 1, 1);
| primes = gx_list_filter (nums, (GXPred)gx_is_prime, NULL);
| sum    = gx_list_sum (primes); /* => 1060 */
| g_list_free (nums);
| g_list_free (primes);

There's also folding, mapping etc. See a short article about this:
(2015?! time does fly). Am still developing it though.
