The signedness of char is implementation defined. Since the alpm_graph state is clearly meant to be signed, make the signedness explicit. This fixes bugs on systems where char is unsigned, in comparissons of the following type: if(v.state == -1) which, if state is unsigned, will never be true due to integer promotion rules. Fixes failing test/pacman/tests/sync012.py when compiling with -funsigned-char. Fixes two warnings [-Wtype-limits] for comparissons with -1 when compiling with -funsigned-char.
