657b04b83b net: enhance decoding of getsockopt's optlen argument
As the last argument of getsockopt syscall has read-write semantics,
print both user and kernel values when they differ.

* net.c (SYS_FUNC(getsockopt)): On entering syscall, fetch and save
the length specified to the kernel.  On error, print the length saved
on entering.  When the saved length and the length returned by the
kernel differ, print both values.

337d3a10ce signal: fix decoding of struct old_sigaction on some architectures
On alpha, struct old_sigaction.sa_flags has a 32-bit type.

On mips, only first word of old_sigaction.sa_mask is read.

On all architectures except alpha and mips that have old sigaction
syscall, struct old_sigaction has sa_restorer field that has to be
decoded.

* signal.c (struct old_sigaction) [ALPHA]: Change sa_flags type
to unsigned int, add ATTRIBUTE_PACKED.
[MIPS]: Dhrink sa_mask array to 1 element.
[!ALPHA && !MIPS]: Define sa_restorer field unconditionally.
(struct old_sigaction32): Likewise.
(decode_old_sigaction) [!current_wordsize]: Initialize sa_restorer field
from old_sigaction32.sa_restorer unconditionally.
[!ALPHA && !MIPS]: Print old_sigaction.sa_restorer if SA_RESTORER flag
is set.

e97a66faa1 Do not reset SIGCHLD handler in tracees to SIG_DFL
While strace resets SIGCHLD handler to the default action so that
waitpid definitely works without losing track of children, tracees
should not inherit this change.

* strace.c (struct exec_params): Add child_sa field.

at startup.
