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 IOW, the Author: comments are quickly out of date,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

The target= setting in xl disk configuration can be used to encode
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.

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.

... and consolidate the cmdline/extra/root parsing to facilitate doing
so.
The logic is the same as xl's parse_cmdline from the current xen.git master
branch (e6f0e099d2c17de47fd86e817b1998db903cab61).
On the formatting side switch to producing cmdline= instead of extra=.
Update a few tests and add serveral more.
- test-cmdline is added to test the exclusive use of cmdline.
- test-fullvirt-direct-kernel-boot.cfg is updated due to the switch
on the formatting side and now tests the exclusive use of cmdline=.
- Tests are added for both paravirt and fullvirt where the .cfg uses
extra= and (paravirt only) root=. These are format (xl->xml) only
since the inverse will generate cmdline= hence is not a round trip
(which was already true if using root=, which used to generate
extra= on the way back).
- Tests are added for both paravirt and fullvirt where the .cfg
declares cmdline= as well as bogus extra= and (paravirt only) root=
entries which should be ignored. Again these are format only tests
since the inverse won't include the bogus lines.
The last two bullets here required splitting the DO_TEST macro into
two halves, as is done in the xmconfigtest.c case.
In order to introduce a use of VIR_WARN for logging I had to add
virerror.h and VIR_LOG_INIT.

xend prior to 4.0 understands vcpus as maxvcpus and vcpu_avail
as a bit map of which cpus are online (default is all).
xend from 4.0 onwards understands maxvcpus as maxvcpus and
vcpus as the number which are online (from 0..N-1). The
upstream commit (68a94cf528e6 "xm: Add maxvcpus support")
claims that if maxvcpus is omitted then the old behaviour
(i.e. obeying vcpu_avail) is retained, but AFAICT it was not,
in this case vcpu==maxcpus==online cpus. This is good for us
because handling anything else would be fiddly.
This patch changes parsing of the virDomainDef maxvcpus and vcpus
entries to use the corresponding 'maxvcpus' and 'vcpus' settings
from xm and xl config. It also drops use of the old Xen 3.x
'vcpu_avail' setting.
The change also removes the maxvcpus limit of MAX_VIRT_VCPUS (since
maxvcpus is simply a count, not a bit mask), which is particularly
crucial on ARM where MAX_VIRT_CPUS == 1 (since all guests are
expected to support vcpu placement, and therefore only the boot
vcpu's info lives in the shared info page).
Existing tests adjusted accordingly, and new tests added for the
'maxvcpus' setting.
Remove use of xendConfigVersion in the xm and xl config formatter/parsers
in src/xenconfig/. Adjust callers in the xen and libxl drivers accordingly.

From xl.cfg950 man page:
spiceagent_mouse=BOOLEAN
Whether SPICE agent is used for client mouse mode. The default is
true (1) (turn on)
spicevdagent=BOOLEAN
Enables spice vdagent. The Spice vdagent is an optional component for
enhancing user experience and performing guest-oriented management
tasks. Its features includes: client mouse mode (no need to grab
mouse by client, no mouse lag), automatic adjustment of screen
resolution, copy and paste (text and image) between client and domU.
It also requires vdagent service installed on domU o.s. to work.
The default is 0.
spice_clipboard_sharing=BOOLEAN
Enables Spice clipboard sharing (copy/paste). It requires spicevdagent
enabled. The default is false (0).
So if spiceagent_mouse is enabled (client mouse mode) or
spice_clipboard_sharing is enabled, spicevdagent must be enabled.
Along with this change, s/spicedvagent/spicevdagent, set
spiceagent_mouse correctly, and add a test for these spice
features.
