Richard Henderson fd87be1dad Accelerators patches
A lot of trivial cleanups and simplifications (moving methods around,
 adding/removing #include statements). Most notable changes:
 
 - Rename NEED_CPU_H -> COMPILING_PER_TARGET
 - Rename few template headers using the '.h.inc' suffix
 - Extract some definitions / declarations into their own header:
   - accel/tcg/user-retaddr.h (helper_retaddr)
   - include/exec/abi_ptr.h (abi_ptr)
   - include/exec/breakpoint.h (CPUBreakpoint, CPUWatchpoint)
   - include/exec/mmu-access-type.h (MMUAccessType)
   - include/user/tswap-target.h (tswapl, bswaptls)

Philippe Mathieu-Daudé 9ad49538c7 accel/whpx: Use accel-specific per-vcpu @dirty field
WHPX has a specific use of the CPUState::vcpu_dirty field
(CPUState::vcpu_dirty is not used by common code).
To make this field accel-specific, add and use a new
@dirty variable in the AccelCPUState structure.

Philippe Mathieu-Daudé 2379866c3b accel/tcg: Rename helper-head.h -> helper-head.h.inc
Since commit 139c1837db ("meson: rename included C source files
to .c.inc"), QEMU standard procedure for included C files is to
use *.c.inc.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:

  If you do use template header files they should be named with
  the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
  being included for expansion.

Therefore rename "exec/helper-head.h" as "exec/helper-head.h.inc".

nbd_negotiate() is already marked coroutine_fn.  And given the fix in
the previous patch to have nbd_negotiate_handle_starttls not create

functions reachable only during option negotiation as also being
coroutine_fn.
