5369a36c4f exec/memory: Add symbolic value for memory listener priority for accel
Add MEMORY_LISTNER_PRIORITY_ACCEL for the symbolic value for the memory
listener to replace the hard-coded value 10 for accel.

No functional change intended.

c5beb26a2f accel: Rename NVMM 'struct qemu_vcpu' -> AccelCPUState
We want all accelerators to share the same opaque pointer in
CPUState. Rename NVMM 'qemu_vcpu' as 'AccelCPUState'; directly
use the typedef, remove unnecessary casts.

f861b3f390 accel: Rename HAX 'struct hax_vcpu_state' -> AccelCPUState
We want all accelerators to share the same opaque pointer in
CPUState. Start with the HAX context, renaming its forward
declarated structure 'hax_vcpu_state' as 'AccelCPUState'.
Document the CPUState field. Directly use the typedef.

Remove the amusing but now unnecessary casts in NVMM / WHPX.

de6cd7599b meson: Replace softmmu_ss -> system_ss
We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.

Mechanical change doing:

  $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

8e3b0cbb72 Replace qemu_real_host_page variables with inlined functions
Replace the global variables with inlined helper functions. getpagesize() is very
likely annotated with a "const" function attribute (at least with glibc), and thus
optimization should apply even better.

This avoids the need for a constructor initialization too.

b21e238037 Use g_new() & friends where that makes obvious sense
g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,
for two reasons.  One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

This commit only touches allocations with size arguments of the form
sizeof(T).

Patch created mechanically with:

    $ spatch --in-place --sp-file scripts/coccinelle/use-g_new-etc.cocci \

0cc4965049 nvmm: Fix support for stable version
NVMM user version 1 is the version being shipped with netbsd-9,
which is the most recent stable branch of NetBSD. This makes it
possible to use the NVMM accelerator on the most recent NetBSD
release, 9.2, which lacks nvmm_cpu_stop.

436c831a28 migration: Unify failure check for migrate_add_blocker()
Most callers check the return value.  Some check whether it set an
error.  Functionally equivalent, but the former tends to be easier on
the eyes, so do that everywhere.

Prior art: commit c6ecec43b2 "qemu-option: Check return value instead
of @err where convenient".
