Eugene Syromyatnikov 762abe0ce3 Use accessors for tcp->s_ent, return a stub struct if it is NULL ...

Since code paths are non-trivial, it's an attempt to future-proof and
prevent improper access of tcp->s_ent fields.

* defs.h (struct tcb): Update the description of s_ent field.
(stub_sysent): New declaration.
(tcp_sysent, n_args): New macro functions.
* ipc.c (SYS_FUNC(ipc)): Use n_args() instead of tcp->s_ent->nargs.
* linux/alpha/get_syscall_args.c (get_syscall_args): Likewise.
* linux/bfin/get_syscall_args.c (get_syscall_args): Likewise.
* linux/hppa/get_syscall_args.c (get_syscall_args): Likewise.
* linux/ia64/get_syscall_args.c (get_syscall_args): Likewise.
* linux/microblaze/get_syscall_args.c (get_syscall_args): Likewise.
* linux/mips/get_syscall_args.c (get_syscall_args): Likewise.
* linux/sh/get_syscall_args.c (get_syscall_args): Likewise.
* linux/sh64/get_syscall_args.c (get_syscall_args): Likewise.
* linux/x86_64/get_syscall_args.c (get_syscall_args): Likewise.
* linux/xtensa/get_syscall_args.c (get_syscall_args): Likewise.
* prctl.c (print_prctl_args): Likewise.
* signal.c (SYS_FUNC(sgetmask)): Likewise.
* util.c (printargs, printargs_u, printargs_d): Likewise.
* syscall.c (decode_ipc_subcall, decode_syscall_subcall: Likewise.
(dumpio, tamper_with_syscall_exiting, syscall_entering_decode,
syscall_entering_decode, syscall_entering_trace, syscall_entering_trace,
syscall_exiting_decode, print_syscall_resume, syscall_exiting_trace,
get_syscall_result): Use tcp_sysent instead of tcp->s_ent().
(stub_sysent): New stub sysent.
(get_scno): Reset scno, s_ent, qual_flg; initialise s->ent from
stub_sysent.
* pathtrace.c (pathtrace_match_set): Use tcp_sysent instead of
tcp->s_ent().
