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: 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.

Popular glibc based distributions[1] require minimum

suboptimal system calls could get used.

Set the minimum kernel advertized to 2.6.32 for

target-alpha: Fixes for alpha-linux syscalls.

1. Add correct definitions of error numbers.
2. Implement SYS_osf_sigprocmask
3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL.

This last requires exposing the FPCR value to do_syscall.
Since this value is actually split up into the float_status,
expose routines from helper.c to access it.

Finally, also add a float_exception_mask field to float_status.
We don't actually use it to control delivery of exceptions to
the emulator yet, but simply hold the value that we placed there
when loading/storing the FPCR.
