dahdi: Add functions for determining spantype (E1/T1) to include/dahdi/kernel.h

Browse Source 
Uses the linecompat member to determine what type of span it is. This will
allow removing T1/E1 flags from other places where the span type is stored.

This function also changes the return value from bool to int for the
inlines defined in include/dahdi/kernel.h. This is because not all
kernel versions include stdbool.h in the headers and it will conflict
with boolean values that are exported via module parameters on some
older kernels if dahdi included it globally.
