d2eaf67486 signal: SIGSYS: decode si_syscall & si_arch fields 
When receiving SIGSYS, the si_syscall & si_arch fields are set to known
values, so make sure we decode their values into the symbol settings.
This makes stracing seccomp failures much easier.

* defs.h (syscall_name): New prototype.
* printsiginfo.c: Include linux/audit.h and xlat/audit_arch.h.
(print_si_info): Decode si_syscall & si_arch for SIGSYS.

(syscall_name): New function.
(trace_syscall_entering): Change undefined_scno_name to syscall_name.
(trace_syscall_exiting): Likewise.
* xlat/audit_arch.in: New file.

383386de73 net.c: recvfrom fixes 
This change fixes these three problems (before/after is shown):

On interrupted syscall, flags are not decoded:

    -recvfrom(3, 0x7fff0a41e306, 10, 2, 0, 0) = ? ERESTARTSYS
    +recvfrom(3, 0x7fff0a41e306, 10, MSG_PEEK, 0, 0) = ? ERESTARTSYS

If peer address is unavalable (example: anon sockets from socketpair()),
kernel returns socklen of 0, but we ignore that and show bogus sockaddr data:

    -recvfrom(3, "123456789\0", 10, MSG_PEEK, {sa_family=0x7777 /* AF_??? */, sa_data="wwwwwwwwwwwwww"}, [0]) = 10
    +recvfrom(3, "123456789\0", 10, MSG_PEEK, 0x7ffde6edf760, [0]) = 10

SYS_FUNC(recvfrom) passes address of fromlen, not fromlen, to printsock():

    -               printsock(tcp, tcp->u_arg[4], tcp->u_arg[5]);
    +               printsock(tcp, tcp->u_arg[4], fromlen);
