The usleep function was missing on older mingw versions, but we can rely
on it existing everywhere these days. It may only support times upto 1
second in duration though, so we'll prefer to use g_usleep instead.

The commandhelper program is not changed since that can't link to glib.
Fortunately it doesn't need to build on Windows platforms either.

Missing semicolon at the end of macros can confuse some analyzers

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 IOW, the Author: comments are quickly out of date,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.

Currently, the functions return a pointer to the
destination buffer on success or NULL on failure.

Not only does this kind of error handling look quite
alien in the context of libvirt, where most functions
return zero on success and a negative int on failure,
but it's also somewhat pointless because unless there's
been a failure the returned pointer will be the same
one passed in by the user, thus offering no additional
value.

Change the functions so that they return an int
instead.

virNetDevLinkDump should have been in virnetlink.c, but that file
didn't exist yet when the function was created. It didn't really
matter until now - I found that having virnetlink.h included by
virnetdev.h caused build problems when trying to #include virnetdev.h
in a .c file in src/conf (due to missing directory in -I). Rather than
fix that to further institutionalize the incorrect placement of this
one function, this patch moves the function.

The existing log messages for this have several problems; there are
two lines of log when one will suffice, they duplicate the function
name in log message (when it's already included by VIR_DEBUG), they're
missing some useful bits, they get logged even when the call is a NOP.

This patch cleans up the problems with those existing logs, and also
adds a new VIR_INFO-level log down at the function that is actually
creating and sending the netlink message that logs *everything* going
into the netlink message (which turns out to be much more useful in
practice for me; I didn't want to eliminate the logs at the existing
location though, in case they are useful in some scenario I'm
unfamiliar with; anyway those logs are remaining at debug level, so it
shouldn't be a bother to anyone).

 if instanceId is NULL

When virNetDevVPortProfileGetStatus() was called with instanceId =
NULL (which is the case for all DISASSOCIATE requests in 802.1Qbh) it
would log the following error:

   Could not find netlink response with expected parameters

even though the disassociate had been successfully completely. Then,
due to the fortunate coincidence of status having been initialized to
0 and then not changed when the "failure" was encountered, it would
still return a status of 0 (PORT_VDP_RESPONSE_SUCCESS), so the caller
would assume a successful operation.

This would result in a spurious log message though, and would fill in
LastErrorMessage, so that the API would return that error if it
happened during cleanup from some other error. That, in turn, would
lead to an incorrect supposition that the response to the port profile
disassociate was the cause of the failure.

During debugging, I noticed that the VF in question usually had *no
uuid* associated with it (big surprise)by the time the disassociate
completed, so the solution is *not* to send the previous instanceId
down.

This patch fixes virNetDevVPortProfileGetStatus() to only check the
VF's uuid in the status if it was given an instanceId to check against
when originally called. Otherwise it only checks that the particular
VF is present (it will be).

This does cause a slight difference in behavior - rather than
returning with status unchanged (and thus always 0) it will actually
get the IFLA_PORT_RESPONSE. This could lead to revelation of error
conditions we were previously ignoring. Or not. So far "not".

Somehow I managed to backspace over the newline between the closing
brace and goto cleanup; in commit 36e244f3.

The previous error message just indicated that the desired response
couldn't be found, this patch tells what was desired, as well as
listing out the entire table that had been in the netlink response, to
give some kind of idea why it failed.

Midonet is an opensource virtual networking that over lays the IP
network between hypervisors. Currently, such networks can be made
with the openvswitch virtualport type.

This patch, defines the schema and documentation that will serve
as basis for the follow up patches that will add support to libvirt
for using Midonet virtual ports for its interfaces. The schema
definition requires that the port profile expresses its interfaceid
as part of the port profile. For that reason, this is part of the
patch too.

virNetDevLinkDump() gets a message from netlink into "resp", then
calls nlmsg_parse() to fill the table "tb" with pointers into resp. It
then returns tb to its caller, but not before freeing the buffer at
resp. That means that all the callers of virNetDevLinkDump() are
examining memory that has already been freed. This can be verified by
filling the buffer at resp with garbage prior to freeing it (or, I
suppose, just running libvirtd under valgrind) then performing some
operation that calls virNetDevLinkDump().

The code has been like this ever since virNetDevLinkDump() was written
- the original author didn't notice it, and neither did later
additional users of the function. It has only been pure luck (or maybe
a lack of heavy load, and/or maybe an allocation algorithm in malloc()
that delays re-use of just-freed memory) that has kept this from
causing errors, for example when configuring a PCI passthrough or
macvtap passthrough network interface.

The solution taken in this patch is the simplest - just return resp to
the caller along with tb, then have the caller free it after they are
finished using the data (pointers) in tb. I alternately could have
made a cleaner interface by creating a new struct that put tb and resp
together along with a vir*Free() function for it, but this function is
only used in a couple places, and I'm not sure there will be
additional new uses of virNetDevLinkDump(), so the value of adding a
new type, extra APIs, etc. is dubious.

I'm about to add a syntax check that enforces our documented
HACKING style of always using matching {} on if-else statements.

This patch focuses on all remaining problems, where there weren't
enough issues to warrant splitting it further.
