print_sigset_addr_len with added minimal length argument.
Treat length less than minimal length or greater than NSIG/8 as invalid.

to 4-byte boundary and initialize it with zeroes so that subsequent
call to sprintsigmask_n will not access uninitialized data.

print_sigset_addr_len_limit with current_wordsize
as a minimal length argument.
(SYS_FUNC(rt_sigpending)): Call print_sigset_addr_len_limit
instead of print_sigset_addr_len with 1 as a minimal length argument.

* strace.c (init): Allow -p option along with a command.

When tracing a command in -f mode, do not check for the command's
threads as it has no threads at this moment.

argument.

Tested on various platforms, including the following combinations
of architectures and kernel headers:
x86_64: 4.4-rc, 4.3, 4.2, 4.1, 3.19, 3.17, 3.16, 3.12, 3.11,
3.10-rhel, 2.6.32-rhel, 2.6.27-sle, 2.6.18-rhel
i386: 4.4-rc, 4.3, 4.2, 4.1, 3.19, 3.17, 3.16, 3.11,
3.10-rhel, 2.6.32-rhel, 2.6.27-sle, 2.6.18-rhel
aarch64: 4.4-rc
alpha: 4.3
arm eabi: 4.4-rc, 4.2, 4.1
hppa: 3.18
ia64: 3.18
mips o32: 4.1
ppc: 3.18
ppc64: 3.10-rhel, 2.6.32-rhel
s390: 3.18
s390x: 3.18
sparc: 4.1
sparc: 3.18
x32: 3.19
The only platform which is known at this moment to fail the test
is CentOS-5 provided by OBS. On x86_64 instance it fails with
error: "prlimit64" syscall #300 is "fanotify_init" in syscallent.h
and on i586 it similarly fails with
error: "prlimit64" syscall #338 is "fanotify_init" in syscallent.h
So this is a real platform bug that is not likely to be worked around
on the strace side.
