Throughout libsepol, values taken from sepolicy are used in
places where length == 0 or length == <saturated> matter,
find and fix these.
Also, correct any type mismatches noticed along the way.

libsepol: fix unitialized jmp and invalid dereference
When initializing role_datum_t array, initialize the array.
This corrects this issue:
==25766== Conditional jump or move depends on uninitialised value(s)

Also, check for NULL when determining if a role can be associated
with a type.
