ipc: fix printing of nsops argument of semop and semtimedop syscalls
According to POSIX, nsops argument of semop syscall has type size_t,
but the kernel treats nsops argument of semop and semtimedop syscalls
as unsigned int.
* ipc_sem.c (tprint_sembuf_array): Change type of "count" argument
from unsigned long to unsigned int, print it using %u format.
Mark io_setup and io_destroy as memory mapping related syscalls
As io_setup syscall allocates some memory using do_mmap_pgoff, and
io_destroy deallocates this memory using vm_munmap, set TRACE_MEMORY
flag for all sysentries of io_setup and io_destroy using the following
oneliner:
sed -ri '/io_setup|io_destroy/ s/0,/TM,/' linux/*/syscallent*.h
* linux/*/syscallent*.h (io_setup, io_destroy): Change sys_flags to TM.
It was incorrectly assumed that __*64 types are long long on all
platforms, despite strace having specially crafted macros in order
to handle precisely this architecture discrepancy.
The commit fixes this oversight.
* tests/aio.c (main): Use PRI__*64 macros for correct format conversion
specifiers for __*64-typed values.
* ipc_msgctl.c (SYS_FUNC(msgctl)): As msqid argument is treated as int
by the kernel, cast it to int and print it using %d format.

ipc: fix printing key_t arguments of msgget, semget, and shmget syscalls
* ipc_msg.c (SYS_FUNC(msgget)): As key_t type in the kernel
is __kernel_key_t (i.e. int), cast key_t argument to int
and print it using %#x format.
* ipc_sem.c (SYS_FUNC(semget)): Likewise.
* ipc_shm.c (SYS_FUNC(shmget)): Likewise.

tests: perform more strict structure allocation in sched_xetattr test
Use tail_alloc with precise size of the structure.
* tests/sched_xetattr.c (main): Eliminate usage of anonymous union type.
Rename sched to sched_attr. Change type of sched_attr to struct
pointer. Use tail_alloc for sched_attr allocation, update printf
statements accrodingly.
* tests/aio.c (main): Do not pass 64-bit aio_context_t to io_submit
and io_getevents until strace learns how to print 64-bit pointers on x32

tests: add more tests for sched_getscheduler and sched_xetscheduler
* tests/sched_xetscheduler.c (main): Check for decoding of invalid PID
in sched_getscheduler and sched_setscheduler, invalid address
of sched_param structure, and invalid policy value.
struct iocb contains two fields with fd semantics: aio_fildes and
aio_resfd. It is quite reasonable to use the appropriate function for
printing them (apart from just "%d").
* aio.c (print_common_flags): Add struct tcb pointer to parameter list;
use printfd for printing aio_resfd field.
(print_iocb_header): Add struct tcb pointer to parameter list;
use printfd for printing aio_fildes field.

As configure.ac does not check for linux/futex.h, HAVE_LINUX_FUTEX_H is
never defined and therefore the inclusion of <linux/futex.h> guarded by
HAVE_LINUX_FUTEX_H makes no sense.
Moreover, <linux/futex.h> used to have an incorrect definition
of FUTEX_WAIT_BITSET_PRIVATE and FUTEX_WAKE_BITSET_PRIVATE:
since kernel commit v2.6.24-6320-gcd68998 where these definitions
were initially introduced and up to v2.6.31-7082-gf8d1e54 where they
were finally fixed these macros had been incorrectly defined via
FUTEX_WAIT_BITS and FUTEX_WAKE_BITS instead of FUTEX_WAIT_BITSET
and FUTEX_WAKE_BITSET, and these incorrect definitions made their way
into some distributions still in use.
futex: avoid printing val when it is not used by the futex command
