The second (level) and third (optname) arguments of getsockopt and
setsockopt syscalls are enums, so treat them consistently as enums:
use "unsigned int" type to avoid potential sign extension issues.

to print address in PTRACE_PEEKUSER and PTRACE_POKEUSER requests.

Define PRI__[uxs]64 macros to print __s64 and __u64 values

Rather than cast every __u64 or __s64 before printing,
define printing helpers for those types directly.
