qemu-char: fix infinite recursion connecting to monitor pty
Since commit
bd5c51e (qemu-char: don't issue CHR_EVENT_OPEN in a BH), an
infinite recursion occurs when putting the monitor on a pty (-monitor
pty) and connecting a terminal to the slave port.
This is because of the qemu_chr_be_event(s, CHR_EVENT_OPENED) added to
qemu_chr_be_generic_open(). This event is captured by monitor_event()
which prints a welcome message to the character device. The flush of
that welcome message retriggers another open event in pty_chr_state()
because it checks s->connected, but only sets it to 1 after calling
qemu_chr_be_generic_open().
I've fixed this by setting s->connected = 1 before the call to
qemu_chr_be_generic_open() instead of after, so that the recursive
pty_chr_state() doesn't call it again.

rdma: IPv6 over Ethernet (RoCE) is broken in linux - workaround
We've gotten reports from multiple testers (including Frank Yangjie
and myself) that RDMA IPv6 support over RocE (Ethernet) is broken
in linux.
A patch to Linux is still in review:
http://comments.gmane.org/gmane.linux.drivers.rdma/16448
If the user is listening on '[::]', then we will not have a opened a device
yet and have no way of verifying if the device is RoCE or not.
In this case, the source VM will throw an error for ALL types of
connections (both IPv4 and IPv6) if the destination machine does not have
a regular infiniband network available for use.
The only way to gaurantee that an error is thrown for broken kernels is
for the management software to choose a *specific* interface at bind time
and validate what time of hardware it is.
Unfortunately, this puts the user in a fix:
If the source VM connects with an IPv4 address without knowing that the
destination has bound to '[::]' the migration will unconditionally fail
unless the management software is not explicitly listening on the the IPv4
address while using a RoCE-based device.
If the source VM connects with an IPv6 address, then we're OK because we can
throw an error on the source (and similarly on the destination).
But in mixed environments, this will be broken for a while until it is fixed
inside linux.
We do provide a *tiny* bit of help in mixed environments, though in this patch:
We can list all of the devices in the system and check to see if all the
devices are RoCE or Infiniband.
If we detect that we have a *pure* RoCE environment, then we can safely
thrown an error even if the management sofware has specified '[::]' as the
bind address.
However, if there is are multiple hetergeneous devices, then we cannot make
this assumption and the user just has to be sure they know what they are doing.

Commit
6d4cd40 fixed qemu_opts_set_defaults() for an existing corner
case, but broke it for another one that can't be reached in current
code.
Quote from its commit message:
I believe [opts_parse()] attempts to do the following:
If options don't yet exist, create new options
Else, if defaults, modify the existing options
Else, if list->merge_lists, modify the existing options
Else, fail
The only caller that passes true for defaults is
qemu_opts_set_defaults().
The commit message then claims:
A straightforward call of qemu_opts_create() does exactly that.
Wrong. When !list->merge_lists, and the option string doesn't contain
id=, and options without ID exist, then we don't actually modify the
existing options, we create new ones.
Not reachable, because we never pass lists with !list->merge_lists to
qemu_opts_set_defaults().
Guard against possible (if unlikely) future misuse with assert().

1) The GPL says that "if the Program does not specify a version number
of this License, you may choose any version ever published by the Free
Software Foundation". This is not true, QEMU includes parts that are
v2-only.
2) Provide a default for files with no licensing information.
3) It is not just hardware emulation that is under BSD license.
4) Restrict GPLv2-only contributions to user mode emulation (due to
code from Linux) and PCI passthrough (due to code from Neocleus).
5) The rules were initially set by Fabrice but are being amended by
other people (already in commit
ee12e1f, LICENSE: There is no libqemu.a
anymore, 2011-11-15). Do not put words in his mouth.

Further, don't needlessly deviate from the scheme of naming PVR constant,
QOM type and device description after the exact revision that is in fact
encoded in the PVR used.
That way, we can change the user-friendly alias -cpu POWER7+ to point to a
different revision if we so desire, while not polluting the type namespace.
This naming scheme is sensible and completely orthogonal to how PVRs may
or may not get matched to CPU types.
