Revert "e1000: no need auto-negotiation if link was down"
This reverts commit 84dd2120247a7d25ff1bb337de21c0e76816ad2d.
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.
Reproduced/tested with qemu-jeos and Ubuntu 12.10.

configure: Keep -Werror enabled for Release Candidates
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/
directory exists in the source tree.

Some of its callers were combining it with FROM_I2C_SLAVE() macro, which
is equally obsolete but needs to be replaced in a type-specific way.

libqtest: Wait for the right child PID after killing QEMU
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).

net: multiqueue support
This patch adds basic multiqueue support for qemu. The idea is simple, an array
of NetClientStates were introduced in NICState, parse_netdev() were extended to
find and match all NetClientStates belongs to the backend and place their
pointers in NICConf. Then qemu_new_nic can setup a N:N mapping between NICStates
that belongs to a nic and NICStates belongs to the netdev. And a queue_index
were introduced in NetClientState to track its index. After this, each peers of
a NICState were abstracted as a queue.
After this change, all NetClientState that belongs to the same backend/nic has
the same id. When use want to change the link status, all NetClientStates that
belongs to the same backend/nic will be also changed. When user want to delete
a device or netdev, all NetClientStates that belongs to the same backend/nic
will be deleted also. Changing or deleting an specific queue is not allowed.

tap: multiqueue support
Recently, linux support multiqueue tap which could let userspace call TUNSETIFF
for a signle device many times to create multiple file descriptors as
independent queues. User could also enable/disabe a specific queue through
TUNSETQUEUE.
The patch adds the generic infrastructure to create multiqueue taps. To achieve
this a new parameter "queues" were introduced to specify how many queues were
expected to be created for tap by qemu itself. Alternatively, management could
also pass multiple pre-created tap file descriptors separated with ':' through a
new parameter fds like -netdev tap,id=hn0,fds="X:Y:..:Z". Multiple vhost file
descriptors could also be passed in this way.
Each TAPState were still associated to a tap fd, which mean multiple TAPStates
were created when user needs multiqueue taps. Since each TAPState contains one
NetClientState, with the multiqueue nic support, an N peers of NetClientState
were built up.
A new parameter, mq_required were introduce in tap_open() to create multiqueue
tap fds.

vhost: multiqueue support
This patch lets vhost support multiqueue. The idea is simple, just launching
multiple threads of vhost and let each of vhost thread processing a subset of
the virtqueues of the device. After this change each emulated device can have
multiple vhost threads as its backend.
To do this, a virtqueue index were introduced to record to first virtqueue that
will be handled by this vhost_net device. Based on this and nvqs, vhost could
calculate its relative index to setup vhost_net device.
Since we may have many vhost/net devices for a virtio-net device. The setting of
guest notifiers were moved out of the starting/stopping of a specific vhost
thread. The vhost_net_{start|stop}() were renamed to
vhost_net_{start|stop}_one(), and a new vhost_net_{start|stop}() were introduced
to configure the guest notifiers and start/stop all vhost/vhost_net devices.
