[PATCH] Convert src/modules to use GLib memory management exclusively.

[Andrei Kholodnyi]

Chris,

you both glib patches are ready to go.
I have added in the first patch following comment:

    spd_malloc and friends are replaced with corresponding glib calls

Besides that I have fixed whitespace errors in both patches.
If you agree with these changes I can push them.

What I'm wondering of is how spd_fdset_copy works.

we have
spd_fdset_copy(TFDSetElement old)
     TFDSetElement new;
...
     return new;

where new is a function's local struct.
