Now that 100% of libvirt code is forbidden in a SUID environment,
we no longer need to worry about whether env variables are
trustworthy or not. The virt-login-shell setuid program, which
does not link to any libvirt code, will purge all environment
variables, except $TERM, before invoking the virt-login-shell-helper
program which uses libvirt.

Now that none of the libvirt.so code will ever run in a setuid
context, we can remove the virIsSUID() method. The global
initializer function can just inline the check itself. The new
inlined check is slightly stronger as it also looks for a
setgid situation.

Missing semicolon at the end of macros can confuse some analyzers
(like cppcheck <filename>), and we have a mix of semicolon and
non-semicolon usage through the code. Let's standardize on using
a semicolon for VIR_ENUM_IMPL calls.
Move the verify() statement to the end of the macro and drop
the semicolon, so the compiler will require callers to add a
semicolon.
While we are touching these call sites, standardize on putting
the closing parenth on its own line, as discussed here:

This is mainly about /dev/sev and its default permissions 0600. Of
course, rule of 'tinfoil' would be that we can't trust anything, but the
probing code in QEMU is considered safe from security's perspective + we
can't create an udev rule for this at the moment, because ioctls and
file system permissions aren't cross-checked in kernel and therefore a
user with read permissions could issue a 'privileged' operation on SEV
which is currently only limited to root.

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 IOW, the Author: comments are quickly out of date,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

This is the first step towards libvirt picking the first available
render node instead of QEMU. It also makes sense for us to be able to do
that, since we allow specifying the node directly for SPICE, so if
there's no render node specified by the user, we should pick the first
available one. The algorithm used for that is essentially the same as
the one QEMU uses.

Create a virscsihost.c and place the functions there. That removes the
last #ifdef __linux__ from virutil.c.
Take the opporunity to also change the function names and in one case
the parameters slightly
Rather than have them mixed in with the virutil apis, create a separate
virvhba.c module and move the vHBA related calls into there. Soon there
will be more added.
Also modify the names of the functions and some arguments to be more
indicative of what is really happening. Adjust the callers respectively.
While I was changing fchosttest, rather than the non-descriptive names
test1...test6, rename them to match what the test is doing.
Currently disk names do not follow the
(regex) /^[fhv]d[a-z]+[0-9]*$/ completely
and hence one can assign disk names like
