Set saner MAX_ARGS (6 or 8) for X86_64 and I386
I noticed that tcp->u_args[MAX_ARGS] array is way larger than
I'd expect: for all arches except HPPA it has 32 (!) elements.
I looked at the code and so far I spotted only one abuser of
this fact: sys_sigreturn. On several arches, it saves sigset_t
into tcp->u_args[1...N] on entry and prints it on exit, a-la
memcpy(&tcp->u_arg[1], &sc.oldmask[0], sizeof(sigset_t))
The problem here is that in glibc sigset_t is insanely large:
128 bytes, and using sizeof(sigset_t) in memcpy will overrun
&tcp->u_args[1] even with MAX_ARGS == 32:
On 32 bits, sizeof(tcp->u_args) == 32*4 == 128 bytes!
We may already have a bug there!
This commit changes the code to save NSIG / 8 bytes only.
NSIG can't ever be > 256, and in practice is <= 129,
thus NSIG / 8 is <= 16 bytes == 4 32-bit words,
and even MAX_ARGS == 5 should be enough for saving signal masks.

The current sparc/linux code uses asm/reg.h, but recent Linux kernels
dropped that header completely. So switch over to the ptrace headers
as those should stick around indefinitely as part of the ABI.

Display mask on enter to sigreturn, not on exit
sys_sigreturn() performs ugly manipulations in order to show
signal mask which is restored by this syscall: on syscall entry,
fetches it from the stack, saves it in tcp->u_arg[]
(where it used to overflow this array - fixed sometime ago),
then retrieves the mask and displays it on syscall exit.
Apparently, the motivation is to make it slightly more obvious
to user that signal mask is restored only when this syscall returns.
IMO, this hardly justifies the necessary hacks. It is much easier
to display the mask at the point when we fetch it - on syscall entry.
While at it, I made it so that we do display returned value/errno.
I see no point in hiding it and showing uninformative "= ?" instead.
Example of pause() being interrupted by ALRM which has installed handler
which re-arms ALRM:
Before the patch:
rt_sigsuspend([INT]) = ? ERESTARTNOHAND (To be restarted)
--- {si_signo=SIGALRM, si_code=SI_KERNEL} (Alarm clock) ---
alarm(1) = 0
sigreturn() = ? (mask now [INT])
After:
rt_sigsuspend([INT]) = ? ERESTARTNOHAND (To be restarted)
--- {si_signo=SIGALRM, si_code=SI_KERNEL} (Alarm clock) ---
alarm(1) = 0
sigreturn() (mask [INT]) = -1 EINTR (Interrupted system call)
* defs.h: Declare struct pt_regs i386_regs and struct pt_regs x86_64_regs.
* syscall.c: Remove "static" keywork from these structures' definitions.
* signal.c (sys_sigreturn): Display mask on enter, not on exit.

get_scno is an unholy mess, make it less horrible
Currently, get_scno does *much* more than "get syscall no".
It checks for post-execve SIGTRAP. It checks for changes
in personality. It retrieves params on entry and registers on exit.
Worse still, it is different in different architectures: for example,
for AVR32 regs are fetched in get_scno(), while for e.g. I386
it is done in syscall_enter().
Another problem is that get_scno() is called on both syscall entry and
syscall exit, which is stupid: we don't need to know scno on syscall
exit, it is already known from last syscall entry and stored in
tcp->scno! In essence, get_scno() does two completely different things
on syscall entry and on exit, they are just mixed into one bottle, like
shampoo and conditioner.
The following patches will try to improve this situation.
This change duplicates get_scno into identical get_scno_on_sysenter,
get_scno_on_sysexit functions. Call them in syscall enter and syscall
exit, correspondingly.
* defs.h: Rename get_scno to get_scno_on_sysenter; declare it only
if USE_PROCFS.
* strace.c (proc_open): Call get_scno_on_sysenter instead of get_scno.
* syscall.c (get_scno): Split into two (so far identical) functions
get_scno_on_sysenter and get_scno_on_sysexit.
(trace_syscall_entering): Call get_scno_on_sysenter instead of get_scno.
(trace_syscall_exiting): Call get_scno_on_sysexit instead of get_scno.

Small optimization in signal and ioctl tables
Trivial shuffling of data tables puts them all in one file,
allowing gcc to see their sizes and eliminate variables
which store these sizes.
Surprisingly, in C mode gcc does not optimize out static const int
variables. Help it by using enums instead.
* defs.h: Stop exporting ioctlent{0,1,2}, nioctlents{0,1,2},
signalent{0,1,2}, nsignals{0,1,2}.
* ioctl.c: Remove definitions of ioctlent{,0,1,2} and nioctlents{,0,1,2}.
* signal.c: Remove definitions of signalent{,0,1,2} and nsignals{,0,1,2}.
* syscall.c: Move above definitions to this file. Make them static const
or enums if suitable.
