Declare tcg_dump_stats() in "tcg/tcg.h" so it can be used out of
accel/tcg/, like by {bsd,linux}-user.
Next commit will register the TCG AccelClass::get_stats handler,
which expects a AccelState, so propagate it to dump_accel_info().

Statistic code is not specific to system emulation (except
cross-page checks) and can be used to analyze user-mode binaries.
Extract statistic related code to its own file: tcg-stats.c,
keeping the original LGPL-2.1-or-later license tag.
Note, this code is not yet reachable by user-mode.

Split icount stuff from system/cpu-timers.h.
There are 17 files which only require icount.h, 7 that only
require cpu-timers.h, and 7 that require both.

The heavily imported "system/cpus.h" header includes "accel-ops.h"
to get AccelOpsClass type declaration. Reduce headers pressure by
forward declaring it in "qemu/typedefs.h", where we already
declare the AccelCPUState type.
Reduce "system/cpus.h" inclusions by only including
"system/accel-ops.h" when necessary.

Headers in include/sysemu/ are not only related to system
*emulation*, they are also used by virtualization. Rename
as system/ which is clearer.
Files renamed manually then mechanical change using sed tool.

Move all of it into accel/tcg/monitor.c. This puts everything
about tcg that is only used by the monitor in the same place.

monitor.c now don't include target specific headers and can

accel/tcg/internal.h contains target specific declarations.
Unit files including it become "target tainted": they can not
be compiled as target agnostic. Rename using the '-target'
suffix to make this explicit.

Currently we report whether the TCG accelerator is in
'one-insn-per-tb' mode in the 'info status' output. This is a pretty
minor piece of TCG specific information, and we want to deprecate the
'singlestep' field of the associated QMP command. Move the
'one-insn-per-tb' reporting to 'info jit'.
We don't need a deprecate-and-drop period for this because the
HMP interface has no stability guarantees.

Since commit a0e61807a3 ("qapi: Remove QMP events and commands from
user-mode builds") we don't generate the "qapi-commands-machine.h"
header in a user-emulation-only build.
Rename 'hmp.c' as 'monitor.c' and move the QMP functions from
cpu-exec.c (which is always compiled) to monitor.c (which is only
compiled when system-emulation is selected).
