In most cases this eliminates one or more calls to
virBufferClearAndReset(), but even when it doesn't it's better because:
1) it makes the code more consistent, making it more likely that new
contributors who are "learning by example" will to the right thing.
2) it protects against future modifications that might have otherwise
needed to add a virBufferClearAndReset()
3) Currently some functions don't call virBufferClearAndReset() only
because they're relying on some subordinate function to call it for
them (e.g. bhyveConnectGetSysinfo() in this patch relies on
virSysinfoFormat() to clear out the buffer when there is an
error). I think this is sloppy behavior, and that the toplevel
function that defines and initializes the buffer should be the
function clearing it at the end.

The XML parser currently calls virCapabilitiesDomainDataLookup during
parsing to find the domain capabilities matching the triple
(virt type, os type, arch)
This is, however, bogus with the QEMU driver as it assumes that there
is an emulator known to the default driver capabilities that matches
this triple. It is entirely possible for the driver to be parsing an
XML file with a custom emulator path specified pointing to a binary
that doesn't exist in the default driver capabilities. This will,
for example be the case on a RHEL host which only installs the host
native emulator to /usr/bin. The user can have built a custom QEMU
for non-native arches into $HOME and wish to use that.
Aside from validation, this call is also used to fill in a machine type
for the guest if not otherwise specified. Again, this data may be
incorrect for the QEMU driver because it is not taking account of
the emulator binary that is referenced.
To start fixing this, move the validation to the post-parse callbacks
where more intelligent driver specific logic can be applied.

gmem: clarify that g_malloc always uses the system allocator
Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.
This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.
This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.
Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.

Many drivers had a comment that they did not validate the incoming
'flags' to virDomainGetXMLDesc() because they were relying on
virDomainDefFormat() to do it instead. This used to be the case
(at least since 461e0f1a and friends in 0.9.4 added unknown flag
checking in general), but regressed in commit 0ecd6851 (1.2.12),
when all of the drivers were changed to pass 'flags' through the
new helper virDomainDefFormatConvertXMLFlags(). Since this helper
silently ignores unknown flags, we need to implement flag checking
in each driver instead.
Annoyingly, this means that any new flag values added will silently
be ignored when targeting an older libvirt, rather than our usual
practice of loudly diagnosing an unsupported flag. Add comments
in domain_conf.[ch] to remind us to be extra vigilant about the
impact when adding flags (a new flag to add data is safe if the
older server omitting the requested data doesn't break things in
the newer client; a new flag to suppress data rather than enhancing
the existing VIR_DOMAIN_XML_SECURE may form a data leak or even a
security hole).
In the qemu driver, there are multiple callers all funnelling to
qemuDomainDefFormatBufInternal(); many of them already validated
flags (and often only a subset of the full set of possible flags),
but for ease of maintenance, we can also check flags at the common
helper function.

This introduces a syntax-check script that validates header files use a
common layout:
/*
...copyright header...
*/
<one blank line>
#ifndef SYMBOL
# define SYMBOL
....content....
#endif /* SYMBOL */
For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:
#ifndef SYMBOL_ALLOW
# error ....
#endif /* SYMBOL_ALLOW */
<one blank line>
The many mistakes this script identifies are then fixed.

In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.
With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to find the
author of a particular bit of code.
This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.
The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

This patch provides a caching mechanism for the device address
extensions uid and fid on S390. For efficient sparse address allocation,
we introduce two hash tables for uid/fid which hold the address set
information per domain. Also in order to improve performance of
searching available value, we introduce our own callbacks for the two
hashtables. In this way, uid/fid is saved in hash key and hash value
could be any non-NULL pointer due to no operation on hash value. That is
also the reason why we don't introduce hash value free callback.

Recently, bhyve started supporting specifying guest CPU topology.
It looks this way:
bhyve -c cpus=C,sockets=S,cores=C,threads=T ...
The old behaviour was bhyve -c C, where C is a number of vCPUs, is
still supported.
So if we have CPU topology in the domain XML, use the new syntax,
otherwise keep the old behaviour.
Also, document this feature in the bhyve driver page.

When adding a new object to the domain object list, there should
have been 2 virObjectRef calls made one for each list into which
the object was placed to match the 2 virObjectUnref calls that
would occur during Remove as part of virHashRemoveEntry when
virObjectFreeHashData is called when the element is removed from
the hash table as set up in virDomainObjListNew.
Some drivers (libxl, lxc, qemu, and vz) handled this inconsistency
by calling virObjectRef upon successful return from virDomainObjListAdd
in order to use virDomainObjEndAPI when done with the returned @vm.
While others (bhyve, openvz, test, and vmware) handled this via only
calling virObjectUnlock upon successful return from virDomainObjListAdd.
This patch will "unify" the approach to use virDomainObjEndAPI
for any @vm successfully returned from virDomainObjListAdd.
Because list removal is so tightly coupled with list addition,
this patch fixes the list removal algorithm to return the object
as entered - "locked and reffed". This way, the callers can then
decide how to uniformly handle add/remove success and failure.
This removes the onus on the caller to "specially handle" the
@vm during removal processing.
The Add/Remove logic allows for some logic simplification such
as in libxl where we can Remove the @vm directly rather than
needing to set a @remove_dom boolean and removing after the
libxlDomainObjEndJob completes as the @vm is locked/reffed.

Rework the code such that virDomainObjListFindByID will always

always do the same cleanup logic to call virDomainObjEndAPI.
Makes accessing the objects much more consistent.
NB:
There were 2 callers (lxcDomainLookupByID and qemuDomainLookupByID)
that were already using the ByID name, but not virDomainObjEndAPI -
these were changed as well in this update/patch.

So far we are repeating the following lines over and over:
if (!(virSomeObjectClass = virClassNew(virClassForObject(),

virSomeObjectDispose)))
return -1;
While this works, it is impossible to do some checking. Firstly,
the class name (the 2nd argument) doesn't match the name in the
code in all cases (the 3rd argument). Secondly, the current style
is needlessly verbose. This commit turns example into following:
if (!(VIR_CLASS_NEW(virSomeObject,
virClassForObject)))

Add a localOnly flag to the virConnectDriver struct which allows a
driver to indicate whether it is local-only, or permits remote
connections. Stateful drivers running inside libvirtd are generally
local only. This allows us to remote the check for uri->server != NULL
from most drivers.

Currently the virDrvConnectOpen method is supposed to handle both
opening an explicit URI and auto-probing a driver if no URI is
given. Introduce a dedicated virDrvConnectURIProbe method to enable the
probing functionality to be split from the driver opening functionality.
It is still possible for NULL to be passed to the virDrvConnectOpen
method after this change, because the remote driver needs special
handling to enable probing of the URI against a remote libvirtd daemon.

For bhyveDomObjFromDomain, bhyveDomainLookupByUUID, and
bhyveDomainLookupByID let's return a locked and referenced
@vm object so that callers can then use the common and more
consistent virDomainObjEndAPI in order to handle cleanup rather
than needing to know that the returned object is locked and
calling virObjectUnlock.
The LookupByName already returns the ref counted and locked object,
so this will make things more consistent.
For bhyveDomainUndefine and bhyveDomainDestroy since the
virDomainObjListRemove will return an unlocked object, we need to
relock before making the EndAPI call.

In the past we updated host-model CPUs with host CPU data by adding a
model and features, but keeping the host-model mode. And since the CPU
model is not normally formatted for host-model CPU defs, we had to pass
the updateCPU flag to the formatting code to be able to properly output
updated host-model CPUs. Libvirt doesn't do this anymore, host-model
CPUs are turned into custom mode CPUs once updated with host CPU data
and thus there's no reason for keeping the hacks inside CPU XML
formatters.
