  arm-semi.c: Handle get/put_user() failure accessing arguments

Rework the handling of arguments to ARM semihosting calls so that we
handle a possible failure return from get_user_ual() or put_user_ual().
(This incidentally silences a lot of warnings from clang about
"expression result unused").

a helper routine for it.

  target-arm: Remove out of date FIXME regarding saturating arithmetic

Remove an out of date FIXME regarding the saturating arithmetic helpers:
we now do pass a pointer to CPUARMState to these helpers, and since
the AREG0 changes went in there is no difference between helper.c
and op_helper.c and therefore no point in moving the functions.

  -----------
  configure: Disable (clang) initializer-overrides warnings

Disable clang's initializer-overrides warnings, as QEMU makes significant
use of the pattern of initializing an array with a range-based default
entry like
    [0 ... 0x1ff] = { GPIO_NONE, 0 }
followed by specific entries which override that default, and clang
would otherwise warn "initializer overrides prior initialization of
this subobject" when it encountered the specific entry.

  configure: avoid compiler warning in pipe2 detection

When building qemu-kvm for openSUSE:Factory, I am getting a
warning in the pipe2 detection performed by configure, which
prevents using --enable-werror.

Change detection code to use return value of pipe2.

  Makefile: Forbid out-of-tree build from a source tree that has been built in

If we try to do an out-of-tree build but the source tree we're building from
has been used in the past for an in-tree build then things will go
confusingly wrong. Specifically, some parts of the build process will pull
in generated files from the old in-tree build (because SRC_PATH is on
the vpath). Diagnose this situation so we can produce a useful error
message and tell the user how to fix it (run distclean in the source tree).
