linux-user: Add strace support for printing arguments of syscalls used to lock and unlock memory

This patch implements strace argument printing functionality for following syscalls:

linux-user: Add strace support for printing arguments of syscalls used to lock and unlock memory

This patch implements strace argument printing functionality for following syscalls:

* mlock, munlock, mlockall, munlockall - lock and unlock memory

int mlock(const void *addr, size_t len)
int munlock(const void *addr, size_t len)
int mlockall(int flags)
int munlockall(void)
man page: https://man7.org/linux/man-pages/man2/mlock.2.html

Implementation notes:

Syscall mlockall() takes an argument that is composed of predefined values
which represent flags that determine the type of locking operation that is
to be performed. For that reason, a printing function "print_mlockall" was
stated in file "strace.list". This printing function uses an already existing
function "print_flags()" to print the "flags" argument. These flags are stated
inside an array "mlockall_flags" that contains values of type "struct flags".
These values are instantiated using an existing macro "FLAG_TARGET()" that
crates aproppriate target flag values based on those defined in files
'/target_syscall.h'. These target flag values were changed from
"TARGET_MLOCKALL_MCL*" to "TARGET_MCL_*" so that they can be aproppriately set
and recognised in "strace.c" with "FLAG_TARGET()". Value for "MCL_ONFAULT"
was added in this patch. This value was also added in "syscall.c" in function
"target_to_host_mlockall_arg()". Because this flag value was added in kernel
version 4.4, it is enwrapped in an #ifdef directive (both in "syscall.c" and
in "strace.c") as to support older kernel versions.
The other syscalls have only primitive argument types, so the
rest of the implementation was handled by stating an appropriate
printing format in file "strace.list". Syscall mlock2() is not implemented in
"syscall.c" and thus it's argument printing is not implemented in this patch.

linux-user: fix TARGET_NR_select

TARGET_NR_select can have three different implementations:

1- to always return -ENOSYS

microblaze, ppc, ppc64

-> TARGET_WANT_NI_OLD_SELECT

2- to take parameters from a structure pointed by arg1
(kernel sys_old_select)

i386, arm, m68k

-> TARGET_WANT_OLD_SYS_SELECT

3- to take parameters from arg[1-5]
(kernel sys_select)

x86_64, alpha, s390x,
cris, sparc, sparc64

Some (new) architectures don't define NR_select,

4- but only NR__newselect with sys_select:

mips, mips64, sh

5- don't define NR__newselect, and use pselect6 syscall:

aarch64, openrisc, tilegx, unicore32

linux-user: Use correct target SHMLBA in shmat()

The shmat() handling needs to do target-specific handling
of the attach address for shmat():
* if the SHM_RND flag is passed, the address is rounded
down to a SHMLBA boundary
* if SHM_RND is not passed, then the call is failed EINVAL
if the address is not a multiple of SHMLBA

Since SHMLBA is target-specific, we need to do this
checking and rounding in QEMU and can't leave it up to the
host syscall.

Allow targets to define TARGET_FORCE_SHMLBA and provide
a target_shmlba() function if appropriate, and update
do_shmat() to honour them.

linux-user: Clean up target_syscall.h header guards

Some of them use guard symbol TARGET_SYSCALL_H, but we also have
CRIS_SYSCALL_H, MICROBLAZE_SYSCALLS_H, TILEGX_SYSCALLS_H and
__UC32_SYSCALL_H__. They all upset scripts/clean-header-guards.pl.

Reuse of the same guard symbol TARGET_SYSCALL_H in multiple headers is
okay as long as they cannot be included together. The script can't
tell, so it warns.

The script dislikes the other guard symbols, too. They don't match
their file name (they should, to make guard collisions less likely),
and __UC32_SYSCALL_H__ is a reserved identifier.

Clean them all up: use guard symbol $target_TARGET_SYSCALL_H for
linux-user/$target/target_sycall.h.

linux-user: arm: Remove ARM_cpsr and similar #defines

The #defines of ARM_cpsr and friends in linux-user/arm/target-syscall.h
can clash with versions in the system headers if building on an
ARM or AArch64 build (though this seems to be dependent on the version
of the system headers). The QEMU defines are not very useful (it's
not clear that they're intended for use with the target_pt_regs struct
rather than (say) the CPUARMState structure) and we only use them in one
function in elfload.c anyway. So just remove the #defines and directly
access regs->uregs[].
