GCC in RHEL-6 complains about listen:
../../src/conf/domain_conf.c:23718: error: declaration of 'listen' shadows a global declaration [-Wshadow]
/usr/include/sys/socket.h:204: error: shadowed declaration is here [-Wshadow]
This renames all the listen to gListen.

This effectively removes virDomainGraphicsListenSetAddress which was
used only to change the address of listen structure and possible change
the listen type. The new function will auto-expand the listens array
and append a new listen.
The old function was used on pre-allocated array of listens and in most
cases it only "add" a new listen. The two remaining uses can access the
listen structure directly.

Introduce a helper to check supported device and domain config and move
the memory hotplug checks to it.
The advantage of this approach is that by default all new features are
considered unsupported by all hypervisors unless specifically changed
rather than the previous approach where every hypervisor would need to
declare that a given feature is unsupported.
While trying to build with -Os couple of compile errors showed
up.
conf/domain_conf.c: In function 'virDomainChrRemove':
conf/domain_conf.c:13666:24: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
virDomainChrDefPtr ret, **arrPtr = NULL;
^
Compiler fails to see that @ret is used only if set in the loop,
but whatever, there's no harm in initializing the variable.
In vboxAttachDrivesNew and _vboxAttachDrivesOld compiler thinks
that @rc may be used uninitialized. Well, not directly, but maybe
after some optimization. Yet again, no harm in initializing a
variable.

After 457ff97fa there are two defects in our code. In both of
them we use a signed variable to hold up a number of snapshots
that domain has. We use a helper function to count the number.
However, the helper function may fail in which case it returns
a negative one and control jumps to cleanup label where an
unsigned variable is used to iterate over array of snapshots. The
loop condition thus compare signed and unsigned variables which
in this specific case ends up badly for us.

Checking whether x > 0 before looping over [0..x] items doesn't make
sense and multi-line body must have curly brackets around it.

Allocate it as soon as we know we will need it.
Add it to def->ngraphics if it's allocated, removing the need
to use the addDesktop and totalPresent variables to track this.
Separate allocation of the def->graphics array from the allocation
and initialization of its first element.
Note that the only possible values of totalPresent at this point
are 0 or 1, because it equals to guiPresent + sdlPresent.
When FRONTEND/Type is not any of "sdl", "gui", "vrdp", we add a DESKTOP.
Use a bool to track this, instead of checking that both
totalPresent ("sdl" or "gui" present) and vrdpPresent are zero.
The virDomainSnapshotDefFormat calls into virDomainDefFormat,
so should be providing a non-NULL virCapsPtr instance. On the
qemu driver we change qemuDomainSnapshotWriteMetadata to also
include caps since it calls virDomainSnapshotDefFormat.

Our domain_conf.* files are big enough. Not only they contain XML
parsing code, but they served as a storage of all functions whose
name is virDomain prefixed. This is just wrong as it gathers not
related functions (and modules) into one big file which is then
harder to maintain. Split virDomainObjList module into a separate
file called virdomainobjlist.[ch].

Add the sysfs_prefix argument to the call to allow for setting the
path for tests to something other than SYSFS_CPU_PATH which is a
derivative of SYSFS_SYSTEM_PATH
Use cpupath for nodeCapsInitNUMAFake and remove SYSFS_CPU_PATH
If the virStringSearch() returns a 0 (zero), then each of the uses
of the call will just jump to cleanup forgetting to free the returned
empty list. Expand the scope a bit of each use and free at cleanup.
This needs to specified in way too many places for a simple validation
check. The ostype/arch/virttype validation checks later in
DomainDefParseXML should catch most of the cases that this was covering.
Since the holdtime is not supported by VBOX SDK, it's being simulated
by sleeping before sending the key-up codes. The key-up codes are
auto-generated based on XT codeset rules (adding of 0x80 to key-down)
which results in the same behavior as for QEMU implementation.
Add a XML element that will allow to specify maximum supportable memory
and the count of memory slots to use with memory hotplug.
To avoid possible confusion and misuse of the new element this patch
also explicitly forbids the use of the maxMemory setting in individual
drivers's post parse callbacks. This limitation will be lifted when the
support is implemented.
Wikipedia's list of common misspellings [1] has a machine-readable
version. This patch fixes those misspellings mentioned in the list
which don't have multiple right variants (as e.g. "accension", which can
be both "accession" and "ascension"), such misspellings are left
untouched. The list of changes was manually re-checked for false
positives.

As there are two possible approaches to define a domain's memory size -
one used with legacy, non-NUMA VMs configured in the <memory> element
and per-node based approach on NUMA machines - the user needs to make
sure that both are specified correctly in the NUMA case.
To avoid this burden on the user I'd like to replace the NUMA case with
automatic totaling of the memory size. To achieve this I need to replace
direct access to the virDomainMemtune's 'max_balloon' field with
two separate getters depending on the desired size.
The two sizes are needed as:
1) Startup memory size doesn't include memory modules in some
hypervisors.
2) After startup these count as the usable memory size.
Note that the comments for the functions are future aware and document
state that will be present after a few later patches.
For VBOX it's most likely that the connection is vbox:///session and it
runs with local non-root account. This caused permission denied when
LOCALSTATEDIR was used to create temp file. This patch makes use of the
virGetUserCacheDirectory to address this problem for non-root users.
