a8f0442fd7 term: do not abort decoding in case of non-verbose output
The case of unset verbose is handled by umoven_or_printaddr, moreover,
exiting at this point is plain wrong and leads to last argument not
being printed while it should be.

* term.c (decode_termios, decode_termio, decode_winsize, decode_ttysize,
decode_modem_flags): Do not check verbose flags explicitly and do not
exit early if it is not set.

c7afb4881f ioctl: assume that all ioctl commands have unsigned int type
In linux, ioctl command number has a 32-bit unsigned integer type:
	fs/ioctl.c:SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned long, arg)
If the kernel completely ignores other bits on 64-bit architectures,
why should strace care?
Let's follow the kernel and treat it as unsigned int.

* defs.h (struct_ioctlent): Change "code" type to "unsigned int".
