Require that all headers are guarded by a symbol named

  LIBVIRT_$FILENAME

where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.

Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

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 IOW, the Author: comments are quickly out of date,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

Introduce virDomainAuditInput and use it to log the evdev passed
to the guest.

Add qemuDomainAddIOThread and qemuDomainDelIOThread in order to add or
remove an IOThread to/from the host either for live or config optoins

The implementation for the 'live' option will use the iothreadpids list
in order to make decision, while the 'config' option will use the
iothreadids list.  Additionally, for deletion each may have to adjust
the iothreadpin list.

IOThreads are implemented by qmp objects, the code makes use of the existing
qemuMonitorAddObject or qemuMonitorDelObject APIs.

Add startup auditing and also hotplug auditing for said devices.

Pass the virStorageSource struct to the auditing function and check if
storage is local before auditing.

Some of these are leftovers from renaming the files, others
are just typos.

Also introduce an ugly awk script to enforce this.

To allow the efficient correlation of container audit messages
with host hosts, include the pid namespace inode in audit
messages.

To bring in line with new naming practice, rename the=
src/util/cgroup.{h,c} files to vircgroup.{h,c}

Currently the LXC driver logs audit messages when a container
is started or stopped. These audit messages, however, contain
the PID of the libvirt_lxc supervisor process. To enable
sysadmins to correlate with audit messages generated by
processes /inside/ the container, we need to include the
container init process PID.

We can't do this in the main 'start' audit message, since
the init PID is not available at that point. Instead we output
a completely new audit record, that lists both PIDs.

* tests/securityselinuxhelper.c: Remove doubled line.

  You should have received a copy of the GNU General Public License

This patch removes the explicit FSF address, and uses above instead
(of course, with inserting 'Lesser' before 'General').

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:

  src/security/security_selinux.h
  src/security/security_driver.h
  src/security/security_selinux.c
  src/security/security_apparmor.h
  src/security/security_apparmor.c
  src/security/security_driver.c

Snapshots alter the set of disk image files opened by qemu, so
they must be audited.  But they don't involve a full disk definition
structure, just the new filename.  Make the next patch easier by
refactoring the audit routines to just operate on file name.

* src/conf/domain_audit.h (virDomainAuditDisk): Update prototype.
* src/conf/domain_audit.c (virDomainAuditDisk): Act on strings,
not definition structures.
(virDomainAuditStart): Update caller.
* src/qemu/qemu_hotplug.c (qemuDomainChangeEjectableMedia)
(qemuDomainAttachPciDiskDevice, qemuDomainAttachSCSIDisk)
(qemuDomainAttachUsbMassstorageDevice)
(qemuDomainDetachPciDiskDevice, qemuDomainDetachDiskDevice):
Likewise.

- create a new "redirdev" element for this purpose

When passing through filesystems from the host to a guest, the
host filesystem passed must be audited

* src/conf/domain_audit.{c,h}: Add virDomainAuditFS

The LXC and UML drivers can both make use of auditing. Move
the qemu_audit.{c,h} files to src/conf/domain_audit.{c,h}

* src/conf/domain_audit.c: Rename from src/qemu/qemu_audit.c
* src/conf/domain_audit.h: Rename from src/qemu/qemu_audit.h
* src/Makefile.am: Remove qemu_audit.{c,h}, add domain_audit.{c,h}
* src/qemu/qemu_audit.h, src/qemu/qemu_cgroup.c,
  src/qemu/qemu_command.c, src/qemu/qemu_driver.c,
  src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c,
  src/qemu/qemu_process.c: Update for changed audit API names
