Fix warn_unused_result warnings from gcc - 2nd approach

While going through the source code of cairoint.h file, I found one more
simpler approach for handling the warnings.
Attached patch has the changes with this approach. ( except the warning
introduced due to usage of strtol). 
This looks somewhat more cleaner.
Please have a look at the patch and provide your inputs on this.

We can adopt this or the earlier one, depending on the community's opinion.
