Log Message:
-----------
linux-user: Remove dead code
We can not use watchpoints in user-mode emulation because we
need the softmmu slow path to detect accesses to watchpointed
memory. This code is expanded as empty stub in "hw/core/cpu.h"
anyway, so we can drop it.

-----------
linux-user: strace now handles unshare syscall args correctly
Syscall unshare did not have custom print function for strace, but it's
argument is same as flags in clone syscall, so it can be easily implemented.
Also updated missing flags from clone_flags.

linux-user: Pass CPUArchState to target_restore_altstack
In most cases we were already passing get_sp_from_cpustate
directly to the function. In other cases, we were passing
a local variable which already contained the same value.
In the rest of the cases, we were passing the stack pointer
out of env directly.

linux-user/s390x: Fix sigframe types
Noticed via gitlab clang-user job:
TEST signals on s390x
../linux-user/s390x/signal.c:258:9: runtime error: \
1.84467e+19 is outside the range of representable values of \
type 'unsigned long'
Which points to the fact that we were performing a double-to-uint64_t
conversion while storing the fp registers, instead of just copying
the data across.
Turns out there are several errors:
target_ulong is the size of the target register, whereas abi_ulong
is the target 'unsigned long' type. Not a big deal here, since we
only support 64-bit s390x, but not correct either.
In target_sigcontext and target ucontext, we used a host pointer
instead of a target pointer, aka abi_ulong.
Fixing this allows the removal of a cast to __put_user.

linux-user/alpha: Rename the sigaction restorer field
Use ka_restorer, in line with TARGET_ARCH_HAS_KA_RESTORER
vs TARGET_ARCH_HAS_SA_RESTORER, since Alpha passes this
field as a syscall argument.

linux-user: Pass ka_restorer to do_sigaction
The value of ka_restorer needs to be saved in sigact_table.
At the moment, the attempt to save it in do_syscall is
improperly clobbering user memory.

This means that we can share the TARGET_NR_rt_sigaction code,

linux-user/alpha: Share code for TARGET_NR_sigaction
There's no longer a difference between the alpha code and
the generic code.
There is a type difference in target_old_sigaction.sa_flags,
which can be resolved with a very much smaller ifdef, which
allows us to finish sharing the target_sigaction definition.

linux-user/elfload: fix filling psinfo->pr_psargs
The current code dumps the memory between arg_start and arg_end,
which contains the argv pointers. This results in the
Core was generated by `<garbage>`
message when opening the core file in GDB. This is because the code is
supposed to dump the actual arg strings. Fix by using arg_strings and
env_strings instead of arg_start and arg_end.
