leb128.h: #include stdint.h, inttypes.h.

	* leb128.h: #include stdint.h, inttypes.h.
	(read_uleb128_to_uint64): Renamed from read_uleb128_to_ull.
	Change to take a uint64_t * argument instead of unsigned long long.
	(read_sleb128_to_uint64): Renamed from read_sleb128_to_ll.
	Change to take an int64_t * argument instead of long long.
