Pull out all the QEMU monitor interaction code to a separate
file. This will make life easier when we need to drop in a
new implementation for the forthcoming QMP machine friendly
monitor support.
Next step is to add formal APIs for each monitor command,
and remove direct commands for sending/receiving generic
data.
* src/Makefile.am: Add qemu_monitor.c to build
* src/qemu/qemu_driver.c: Remove code for monitor interaction
* src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: New
file for monitor interaction

* src/conf/interface_conf.c: This was causing subsequent calls to
virXPathxxx() to fail, since ctxt->node was left pointing at the
dhcp node, rather than the protocol node.
* src/util/xml.c: The virXPath... function take extra care to preserve
the XPath context node (ctxt->node) but in the case of virXPathString
and virXPathBoolean they forgot to do this on the error path. This
patch fixes this and move all ctxt->node = relnode instuctions just
after the xmlXPathEval() to make sure this doesn't happen if this code
is modified.
The python method help docs are copied across from the C
funtion comments, but in the process all line breaks and
indentation was being lost. This made the resulting text
and code examples completely unreadable. Both the API
doc extractor and the python generator were destroying
whitespace & this fixes them to preserve it exactly.
* docs/apibuild.py: Preserve all whitespace when extracting
function comments. Print function comment inside a <![CDATA[
section to fully preserve all whitespace. Look for the
word 'returns' to describe return values, instead of 'return'
to avoid getting confused with code examples including the
C 'return' statement.
* python/generator.py: Preserve all whitespace when printing
function help docs
* src/libvirt.c: Change any return parameter indicated by
'return' to be 'returns', to avoid confusing the API extractor

Currently, libvirtd will start a dnsmasq process for the virtual
network, but (aside from killing the dnsmasq process and replacing it),
there's no way to define tftp boot options.
This change introduces the appropriate tags to the dhcp configuration:
<network>
<name>default</name>
<bridge name="virbr%d" />
<forward/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<tftp root="/var/lib/tftproot" />
<dhcp>
<range start="192.168.122.2" end="192.168.122.254" />
<bootp file="pxeboot.img"/>
</dhcp>
</ip>
</network>
When the attributes are present, these are passed to the
arguments to dnsmasq:
dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^
from <tftp /> from <bootp />
At present, only local tftp servers are supported (ie, dnsmasq runs as
the tftp server), but we could improve this in future by adding a
server= attribute.

Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string. If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL. Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string. This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

Latest upstream QEMU can be built with Xen support, which introduces
a -xen-domid argument. This was mistakenly detected as -domid due
to old Xenner support. Adapt to cope with both syntax. Also only
set domid if the virt type is xen, or the guest type is xen
* src/qemu_conf.c, src/qemu_conf.h: Detect new -xen-domid flag in
preference to -domid.

The commit cb51aa48a7 "Fix up connection
reference counting." changed the driver closing and virConnectPtr
unref-logic in virConnectClose().
Before this commit virConnectClose() closed all drivers of the given
virConnectPtr and virUnrefConnect()'ed it afterwards. After this
commit the driver-closing is done in virUnrefConnect() if and only if
the ref-count of the virConnectPtr dropped to zero.
This change in execution order leads to a virConnectPtr leak, at least
for connections to Xen.
The relevant call sequences:
virConnectOpen() -> xenUnifiedOpen() ...
... xenInotifyOpen() -> virConnectRef(conn)
... xenStoreOpen() -> xenStoreAddWatch() -> conn->refs++
virConnectClose() -> xenUnifiedClose() ...
... xenInotifyClose() -> virUnrefConnect(conn)
... xenStoreClose() -> xenStoreRemoveWatch() -> virUnrefConnect(conn)
Before the commit this additional virConnectRef/virUnrefConnect calls
where no problem, because virConnectClose() closed the drivers
explicitly and the additional refs added by the Xen subdrivers were
removed properly. After the commit this additional refs result in a
virConnectPtr leak (including a leak of the hypercall file handle;
that's how I noticed this problem), because now the drivers are only
close if and only if the ref-count drops to zero, but this cannot
happen anymore, because the additional refs from the Xen subdrivers
would only be removed if the drivers get closed, but that doesn't
happen because the ref-count cannot drop to zero.
The fix for this problem is simple: remove the
virConnectRef/virUnrefConnect calls from the Xen subdrivers (see
attached patch). Maybe someone could explain why the Xen Inotify and
Xen Store driver do this extra ref-counting, but none of the other Xen
subdrivers. It seems unnecessary to me and can be removed without
problems.
