If neither explicit semihosting args nor -kernel are used,
make SYS_GET_CMDLINE return an empty string.

Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

In order to run unit tests under semihosting, it is necessary to pass the
application exit code back to the system.
ARM defines only the code to be used for non-error application exit
(ADP_Stopped_ApplicationExit), all other codes should return non-zero
exit codes.
This patch checks if the application code passed via TARGET_SYS_EXIT is
ADP_Stopped_ApplicationExit, and return 0, otherwise return 1.

Callback implementations were specific to arm and m68k, so can easily
cast to ARMCPU and M68kCPU respectively.
Prepares for changing GDBState::c_cpu to CPUState.

Make cpustats monitor command available unconditionally.
Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec()
arguments to CPUState.

The recent rearrangement of include files had some minor errors:
devices.h is not ARM specific and should not be in arm/
arm.h should be in arm/
Move these two headers to correct this.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.

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").
