In multiqueue, all NetClientState that belongs to the same netdev or nic has the
same id. So this patches introduces an helper qemu_find_net_clients_except()
which finds all NetClientState with the same id. This will be used by multiqueue
networking.

When running "make check" with gcov enabled, we get the following
message:
hw/tmp105.gcda:cannot open data file, assuming not executed
The problem happens because:
* tmp105-test exits before QEMU exits, because waitpid() at
qtest_quit() fails;
* waitpid() fails because there's another process already
waiting for the QEMU process;
* The process that is already waiting for QEMU is the child created by
qtest_init() to run system();
* qtest_quit() is incorrectly waiting for the QEMU PID directly instead
of the child created by qtest_init().
This fixes the problem by sending SIGTERM to QEMU, but waiting for the
child process created by qtest_init() (that exits immediately after QEMU
exits).

The automatic drop of -Werror during the RC phases has in the past led
to warnings creeping into submaintainer trees.
Last QEMU Summit it was concluded that -Werror should stay on and
enabled only as part of the release process.
To relieve our release manager, instead of always enabling -Werror or
doing some number magic, let's enable it depending on whether a .git/

This reverts commit 84dd212024.
I'm not sure what issue the original commit was meant to fix, or if
the logic is actually wrong, but it causes e1000 to stop working
after a guest issues a reset.
>From what I can tell a guest with an e1000 nic has no way of changing
the link status, as far as it's NetClient peer is concerned, except
in the auto-negotiation path, so with this patch in place there's no
recovery after a reset, since the link goes down and stays that way.
Revert this patch now to fix the bigger problem, and handle any
lingering issues with a follow-up.

Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d9 (s390:
I/O interrupt and machine check injection.) added functions
cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument,
claiming consistency with cpu_inject_ext().
This complicates making cpu_interrupt() take a CPUState even more and it
required to pass &cpu->env from some S390CPU-aware call sites already,
creating inconsistency elsewhere. Address that.
This also eliminates the need for CPUS390XState in s390_virtio_irq().

The bit that makes a dcbz instruction a dcbzl instruction was declared as
reserved in ppc32 ISAs. However, hardware simply ignores the bit, making
code valid if it simply invokes dcbzl instead of dcbz even on 750 and G4.
Thus, mark the bit as unreserved so that we properly emulate a simple dcbz
in case we're running on non-G5s.
While at it, also refactor the code to check the 970 special case during
runtime. This way we don't need to differenciate between a 970 dcbz and
any other dcbz anymore. We also allow for future improvements to add e500mc
dcbz handling.

Sign-extend the result of LWR, as is already done for LWL. This is necessary
in the case where LWR loads the full word (i.e. the address is actually
aligned). In the other cases, it is implementation defined whether the
upper 32 bits of the result are unchanged or a copy of bit 31. The latter
seems easier to implement.
Previously the code used:
(oldval & (0xfffffffe << (31 - bitshift))) | (newval >> bitshift)
which zeroed the upper bits of the register, losing any previous sign
extension in the unaligned cases.
