Require that all headers are guarded by a symbol named

  LIBVIRT_$FILENAME

where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.

Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

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 IOW, the Author: comments are quickly out of date,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 change actually changes the behaviour of xenConfigGetString() as
now it returns a newly-allocated string.

Unfortunately, there's not much that can be done in order to avoid that
and all the callers have to be changed in order to avoid leaking the
return value.

Also, as a side-effect of the change above, the function now takes a
"char **" argument instead of a "const char **" one.

Allow to store driver specific data on a per-vcpu basis.

Move of the virDomainDef*Vcpus* functions was necessary as
virDomainXMLOptionPtr was declared below this block and I didn't want to
split the function headers.

According to current xl.cfg docs and xl codes, it uses type=vif
instead of type=netfront.

Currently after domxml-to-native, libvirt xml model=netfront will be
converted to xl type=netfront. This has no problem before, xen codes
for a long time just check type=ioemu, if not, set type to _VIF.

Since libxl uses parse_nic_config to avoid duplicate codes, it
compares 'type=vif' and 'type=ioemu' for valid parameters, others
are considered as invalid, thus we have problem with type=netfront
in xl config file.
 #xl create sles12gm-hvm.orig
 Parsing config from sles12gm-hvm.orig
 Invalid parameter `type'.

Correct the conversion in libvirt, so that it matchs libxl codes
and also xl.cfg.

The current code was a little bit odd.  At first we've removed all
possible implicit input devices from domain definition to add them later
back if there was any graphics device defined while parsing XML
description.  That's not all, while formating domain definition to XML
description we at first ignore any input devices with bus different to
USB and VIRTIO and few lines later we add implicit input devices to XML.

This seems to me as a lot of code for nothing.  This patch may look
to be more complicated than original approach, but this is a preferred
way to modify/add driver specific stuff only in those drivers and not
deal with them in common parsing/formating functions.

The update is to add those implicit input devices into config XML to
follow the real HW configuration visible by guest OS.

There was also inconsistence between our behavior and QEMU's in the way,
that in QEMU there is no way how to disable those implicit input devices
for x86 architecture and they are available always, even without graphics
device.  This applies also to XEN hypervisor.  VZ driver already does its
part by putting correct implicit devices into live XML.

XM and XL config are very similar.  Disks are specified differently
in XL, but the old XM disk config is still supported by XL.  XL also
supports new config like spice that was never supported by XM.

This patch moves all the common parsing and formatting functions to
the new file xen_common.c and adapts the XM parser/formatter accordingly.
This restructuring paves way for introducing an XL parser/formatter in
the future.

While moving the code, fixup whitespace, comments, and style issues.
