43b7c24994 Introduce print_sigset_addr function
As the definition of NSIG_BYTES is based on NSIG defined in <signal.h>,
NSIG_BYTES cannot be used in files that use kernel sigset_t.

Add another wrapper around print_sigset_addr_len_limit function that
takes one argument less than print_sigset_addr_len wrapper.  This new
wrapper is going to be used in cases when the length argument is equal
to NSIG_BYTES.

6a360e2f3e x32: implement automatic argument truncation for compat syscalls
x32 syscalls starting with number 512 are compat syscalls that operate
on compat types.  Set COMPAT_SYSCALL_TYPES flag to these syscall entries
and make get_syscall_args truncate arguments of syscalls that have this
flag set, to avoid unpleasant alternative of adding multiple
widen_to_ulong invocations to individual syscall parsers.

preadv, pwritev, preadv2, and pwritev2 are exceptions: while these
syscalls operate on compat types, the offset argument has a regular
64-bit type, so the automatic argument truncation cannot be applied.

Do not assume that some syscalls do not generate syscall-exit-stops.

The solution is to wait for an actual exit reported by PTRACE_EVENT_EXIT
and print the end of unfinished exiting syscall properly.
