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)

Besides, since commit 6a0057aa22 ("docs/devel: make a statement

3b28c27067 accel/tcg: Un-inline retaddr helpers to 'user-retaddr.h'
set_helper_retaddr() is only used in accel/tcg/user-exec.c.

clear_helper_retaddr() is only used in accel/tcg/cpu-exec.c
and accel/tcg/user-exec.c.

No need to expose their definitions to all user-emulation
files including "exec/cpu_ldst.h", move them to a new

accel/tcg/ files requires the following definitions:

  - TARGET_PHYS_ADDR_SPACE_BITS
  - TCG_GUEST_DEFAULT_MO

The first 3 are defined in "cpu-param.h". The last one
in "cpu.h", with a bunch of definitions irrelevant for
TCG. By moving the TCG_GUEST_DEFAULT_MO definition to
"cpu-param.h", we can simplify various accel/tcg includes.

nbd_negotiate() is already marked coroutine_fn.  And given the fix in
the previous patch to have nbd_negotiate_handle_starttls not create
and wait on a g_main_loop (as that would violate coroutine
constraints), it is worth marking the rest of the related static
functions reachable only during option negotiation as also being
coroutine_fn.

Since the calls are elided when KVM is not available,
we can remove the stubs (which are never compiled).

ae6d91a7e9 nbd/server: do not poll within a coroutine context
Coroutines are not supposed to block. Instead, they should yield.

The client performs TLS upgrade outside of an AIOContext, during
synchronous handshake; this still requires g_main_loop.  But the
server responds to TLS upgrade inside a coroutine, so a nested
g_main_loop is wrong.  Since the two callbacks no longer share more
than the setting of data.complete and data.error, it's just as easy to
use static helpers instead of trying to share a common code path.  It
is also possible to add assertions that no other code is interfering
with the eventual path to qio reaching the callback, whether or not it
required a yield or main loop.

Fixes: f95910f ("nbd: implement TLS support in the protocol negotiation")

Module is a level above the core, thereby supporting numa
configuration on the module level can bring user more numa flexibility.

This is the natural further support for module level.
