The i386 backend already has these functions, and the aarch64 backend
could easily split out one. Nothing is done with these functions yet,
but this will aid register allocation of INDEX_op_dup_vec in a later patch.
Adjust the aarch64 tcg_out_dupi_vec signature to match the new interface.
Review
The only fixed_reg is cpu_env, and it should not be modified
during any TB. Therefore code that tries to special-case moves
into a fixed_reg is dead. Remove it.

Allow the backend to expand dup from memory directly, instead of
forcing the value into a temp first. This is especially important
if integer/vector register moves do not exist.
Note that officially tcg_out_dupm_vec is allowed to fail.
If it did, we could fix this up relatively easily:
VECE ==
Use tcg_can_emit_vec_op instead of just TCG_TARGET_HAS_neg_vec,
so that we check the type and vece for the actual operation.

I've submitted a patchset which I think should fix this, but if you
could test that it actually does handle large images correctly that
would be great.

Fix support for the SIOCATMARK and SIOCGPGRP ioctls for xtensa by
correcting corresponding macro definition.
Values for TARGET_SIOCATMARK and TARGET_SIOCGPGRP are determined by
Linux kernel. Following relevant lines are from kernel source tree:
arch/ia64/include/uapi/a
Since Linux v3.17, the kernel's Image header includes a field image_size,
which gives the total size of the kernel including unpopulated data
sections such as the BSS). If this is present, then return it from
load_aarch64_image() as the true size of the kernel rather than
just using the size of the
Gotcha, thanks for the tip!

Commit 463e0be10 ('blockjob: add AioContext attached callback') tried to
make block jobs robust against AioContext changes of their main node,
but it never made sure that the job coroutine actually runs in the new
thread.

net_client_init() uses a variable length array to store the prefix
of 'ipv6-net' parameter (e.g. if ipv6-net=fec0::0/64, the prefix
is 'fec0::0').
Since the IPv6 prefix can be at most as long as an IPv6 address,
we can use an array with fixed size equals to INET6_ADDRSTRLEN.
