c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

19d74fdf0e conf, qemu, security, tests: introducing 'def->tpms' array
A TPM Proxy device can coexist with a regular TPM, but the
current domain definition supports only a single TPM device
in the 'tpm' pointer. This patch replaces this existing pointer
in the domain definition to an array of TPM devices.

All files that references the old pointer were adapted to
handle the new array instead. virDomainDefParseXML() TPM related
code was adapted to handle the parsing of an extra TPM device.
TPM validations after this new scenario will be updated in
the next patch.

ca49b6eccf conf: Get rid of "no_memory" labels
As pointed out by Ján Tomko, "no_memory seems suspicious in the times of

As libvirt decided to take the path to not report OOM and simply abort
when it happens, let's get rid of the no_memory labels and simplify the
code around them.

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 IOW, the Author: comments are quickly out of date,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

ae5d30a0b3 conf: Wire up the vhost-scsi connection from/to XML
With the QEMU components in place, provide the XML parsing to
invoke that code when given the following XML snippet:

    <hostdev mode='subsystem' type='scsi_host'>
      <source protocol='vhost' wwpn='naa.501234567890abcd'/>
    </hostdev>

An optional address element can be specified within the hostdev
(pick CCW or PCI as necessary):

    <address type='ccw' cssid='0xfe' ssid='0x0' devno='0x0625'/>
    <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>

Add basic vhost-scsi tests which were cloned from hostdev-scsi-virtio-scsi
in both xml2argv and xml2xml. Added ones for both vhost-scsi-ccw and
vhost-scsi-pci since the syntaxes are slightly different between them.

Also adjusted the docs to describe the changes.
