967f4eebdc xenconfig: Add support for max_event_channels
Add support in the domXML<->native config converter for max_event_channels.
The parser and formater functions for max_grant_frames were reworked to
also parse max_event_channels. In doing so the xenbus controller is added
earlier in the config parsing, requiring a small adjustment to one of the
existing tests. Include a new test for the event channel conversion.

600462834f Remove all Author(s): lines from source file headers
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 IOW, the Author: comments are quickly out of date,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.

6604a3dd9f xenconfig: support xl<->xml conversion of rbd disk devices

meta info that is meaningful to a backend. Leverage this fact to
support qdisk network disk types such as rbd. E.g. <disk> config
such as

   <disk type='network' device='disk'>
     <driver name='qemu' type='raw'/>
     <source protocol='rbd' name='pool/image'>
       <host name='mon1.example.org' port='6321'/>
       <host name='mon2.example.org' port='6322'/>
       <host name='mon3.example.org' port='6322'/>
     </source>
     <target dev='hdb' bus='ide'/>
     <address type='drive' controller='0' bus='0' target='0' unit='1'/>
   </disk>

can be converted to the following xl config (and vice versa)

  disk = [ "format=raw,vdev=hdb,access=rw,backendtype=qdisk,
            target=rbd:pool/image:auth_supported=none:mon_host=mon1.example.org\\:6321\\;mon2.example.org\\:6322\\;mon3.example.org\\:6322"
         ]

Note that in xl disk config, a literal backslash in target= must
be escaped with a backslash. Conversion of <auth> config is not
handled in this patch, but can be done in a follow-up patch.

Also add a test for the conversions.

a44f1f85f9 xenconfig: produce key=value disk config syntax in xl formatter
The most formal form of xl disk configuration uses key=value
syntax to define each configuration item, e.g.

format=raw, vdev=xvda, access=rw, backendtype=phy, target=disksrc

Change the xl disk formatter to produce this syntax, which allows
target= to contain meta info needed to setup a network-based
disksrc (e.g. rbd, nbd, iscsi). For details on xl disk config
format, see  $xen-src/docs/misc/xl-disk-configuration.txt

Update the disk config in the tests to use the formal syntax.
But add tests to ensure disks specified with the positional
parameter syntax are correctly converted to <disk> XML.
