The admin protocol RPC messages are only intended for use by the user
running the daemon. As such they should not be allowed for any client
UID that does not match the server UID.

The make_nonnull_XXX methods can all fail due to OOM but this was being
silently ignored and thus also not checked by callers. Make the methods
propagate errors and use ATTRIBUTE_RETURN_CHECK to force callers to deal
with it.

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 IOW, the Author: comments are quickly out of date,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

We don't have any per-client private data we need to persist, but the
RPC infrastructure requires that we provide the callbacks and serialize
an empty JSON object. This makes us future proof going forwards.

The admin server functionality is a generic concept that should be wired
up into all libvirt daemons, but is currently integrated with the
libvirtd code. Move it all into the src/admin directory to prepare for
broader reuse.
