[PATCH 2/2] shared: Print .c file/line number in x* routines

[Bryce Harrington]

Switches from inline to pre-processor definitions in order to utilize
__FILE__ and __LINE__ from the .c file in order to display the location
of memory allocation failures when failing.

Now xmalloc, et al calls will produce:

    [weston-info] clients/weston-info.c:714: out of memory (1024)
