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.

As pointed out by Ján Tomko, "no_memory seems suspicious in the times of
abort()".
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.

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 IOW, the Author: comments are quickly out of date,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

Although theoretically both should be the same value, the niothreadids
should be used in favor of iothreads when performing comparisons. This
leaves the iothreads as a purely numeric value to be saved in the config
file. The one exception to the rule is virDomainIOThreadIDDefArrayInit
where the iothreadids are being generated from the iothreads count since
iothreadids were added after initial iothreads support.
Since the balloon driver does not guarantee that it returns memory to
the host, using the value in the audit message is not a good idea.

between a 'scsi_host' and an 'iSCSI host' device.
