ab9afee6e7 virsysinfo: Define and use auto cleanup func for virSysinfoDef properly
What we are using really is heap allocated structure rather than
stack allocated. And for that it's better to use g_autoptr() +
G_DEFINE_AUTOPTR_CLEANUP_FUNC() combo, as Glib documentation for
g_auto() reads:

  This is meant to be used with stack-allocated structures and
  non-pointer types. For the (more commonly used) pointer
  version, see g_autoptr().

This will be even more visible, when virSysinfoDefPtr type is
gone. Stay tuned.

b44898dd31 virsysinfo: Parse OEM strings
Setting OEM strings for a domain was introduced in
v4.1.0-rc1~315. However, any application that wanted to use them
(e.g. to point to an URL where a config file is stored) had to
'dmidecode -u --oem-string N' (where N is index of the string).
Well, we can expose them under our <sysinfo/> XML and if the
domain is running Libvirt inside it can be obtained using
virConnectGetSysinfo() API.

d954fbc74e sysinfotest: Move from custom dmidecode scripts to virCommandSetDryRun()
Problem with custom dmidecode scripts is that they are hard to
modify, especially if we will want them to act differently based
on passed arguments. So far, we have two scripts which do no more
than 'cat $sysinfo' where $sysinfo is saved dmidecode output.

The virCommandSetDryRun() can be used to trick
virSysinfoReadDMI() thinking it executed real dmidecode.

2ee837a68c sysinfotest: Dissolve sysinfotest_run() in testSysinfo()
There is no real need to have two separate functions. They can be
merged together which not only saves couple of lines, but
prepares the structure of the code for future expansion. See next

ac61c9cfc3 virsysinfo: Rename virSysinfoReadX86 to virSysinfoReadDMI
There's nothing x86 specific about this function. Rename the
function so that it has DMI suffix which enables it to be reused

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 IOW, the Author: comments are quickly out of date,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

All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

85128e2962 sysinfo: Fix reports on ARM
Due to a kernel commit (b4b8f770e), cpuinfo format has changed on
ARMs. Firstly, 'Processor: ...' may not be reported, it's
replaced by 'model name: ...'. Secondly, the "Processor" string
may occur in CPU name, e.g. 'ARMv7 Processor rev 5 (v7l)'.
Therefore, we must firstly look for 'model name' and then for
'Processor' if not found.
Moreover, lines in the cpuinfo file are shuffled, so we better
not manipulate the pointer to start of internal buffer as we may
lost some info.
