This fixes a bug in that cpu_loop was not handling the

a bug in that cpu_loop extracted the wrong bits for the

Split out the parts that are only used in linux-user itself

three things:
* the definition of the TaskState struct
* the user-access functions and macros
* do_brk()

The addition of all the extra #include lines was done with

Some platforms used the wrong definition of stack_t where the flags and

of int.
Due to the presence of padding space in the structure and the prevalence
of little-endian machines this problem went unnoticed for a long time.
The type definitions have been cross-checked with the ones defined in
the Linux kernel v5.9, plus some older versions for a few architecture
that have been removed and Xilinx's kernel fork for NiosII [1].
The bsd-user headers remain unchanged as I don't know if they are wrong

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.

For architectures where the input file is not named syscall_nr.tbl,
syscall_nr.h has to be a source file; it's just a forwarder for x86

Handle EXCP_FPE properly for MIPS in cpu loop.
Note that a vast majority of FP instructions are not affected by
the absence of the code in this patch, as they use alternative code
paths for handling floating point exceptions (see, for example,
invocations of update_fcr31()) - they rely on softfloat library for
keeping track on exceptions that needs to be raised. However, there
are few MIPS FP instructions (an example is CTC1) that use function
do_raise_exception() directly, and they need the case that is added
in this patch to propagate the FPE exception as designed.
The code is based on kernel's function force_fcr31_sig() in

Bring target_flock definitions to be more in sync with the way
flock is defined in kernel.
Basically, the rules from the kernel are:
1. Majority of architectures have a common flock definition.
2. Architectures with 32-bit MIPS ABIs have a sligtly different
flock definition; those architectures are the only arcitectures
that have HAVE_ARCH_STRUCT_FLOCK defined, and that preprocessor
constant is used in the common header as a flag for including or
not including common flock definition.
3. Sparc architectures also have a sligtly different flock
definition, but the difference is only the padding at the end of
the structure. The presence of that padding is determined by
preprocessor constants __ARCH_FLOCK6_PAD and __ARCH_FLOCK64_PAD.
QEMU linux-user already implements rules 1. and 3. in a very
similar way as they are implemented in kernel. However, rule 2.
is implemented in a dissimilar way (for example, the constant
TARGET_HAVE_ARCH_STRUCT_FLOCK is missing), and this patch brings
QEMU implementation much closer to the kernel implementation.
TARGET_HAVE_ARCH_STRUCT_FLOCK64 constant is also introduced to
mimic HAVE_ARCH_STRUCT_FLOCK64 from kernel, but it is not defined
anywhere, however, this is the case with HAVE_ARCH_STRUCT_FLOCK64
in kernel as well.
