Markus Armbruster 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 \
	     --macro-file scripts/cocci-macro-file.h FILES...

nia 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.

Markus Armbruster 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".
