ab6ca81276 rbd: Utilize storage pool namespace to manage config options
Allow for adjustment of RBD configuration options via Storage
Pool XML Namespace adjustments. When namespace arguments are
used to start the pool, add a VIR_WARN to indicate that the
startup was tainted by custom config_opts.

7a227688a8 storage: Add infrastructure to manage XML namespace options
Introduce the virStoragePoolFSMountOptionsDef to be used to
manage the Storage Pool XML Namespace for mount options.

Using a new virStorageBackendNamespaceInit function, set the
virStoragePoolXMLNamespace into the _virStoragePoolOptions when
the storage backend is loaded.

Modify the storagepool.rng to allow for the usage of a different
XML namespace to parse the fs_mount_opts to be included with
the fs and netfs storage pool definitions.

Modify the storagepoolxml2xmltest to utilize a properly modified
XML file to parse and format the namespace for a netfs storage pool.

f00cde7f11 storage: Add default mount options for fs/netfs storage pools
https://bugzilla.redhat.com/show_bug.cgi?id=1584663

Modify the command generation to add some default options to the
fs/netfs storage pools based on the OS type. For Linux, it'll be
the "nodev, nosuid, noexec". For FreeBSD, it'll be "nosuid, noexec".
For others, just leave the options alone.

Modify the storagepoolxml2argvtest to handle the fact that the
same input XML could generate different output XML based on whether
Linux, FreeBSD, or other was being built.

virt-aa-helper: generate rules for gl enabled graphics devices
This adds the virt-aa-helper support for gl enabled graphics devices to
generate rules for the needed rendernode paths.

Example in domain xml:
<graphics type='spice'>
  <gl enable='yes' rendernode='/dev/dri/bar'/>
</graphics>

results in:
  "/dev/dri/bar" rw,

Special cases are:
- multiple devices with rendernodes -> all are added
- non explicit rendernodes -> follow recently added virHostGetDRMRenderNode
- rendernode without opengl (in egl-headless for example) -> still add
  the node

f80eae8c2a qemu: command: Don't format image properties for empty -drive
If a -drive has no image, using image properties makes qemu whine that
they should not be used.

This patch stops formating cache/readonly/... for empty drives
for the pre-blockdev syntax. Unfortunately those parameters can't be
added later when inserting media, but on the other hand qemu will start
with an empty drive.

Since we already were able to start a VM with such config previously due
to qemu ignoring them I've opted just to skip formatting them.
Additionally with -blockdev support it will work as expected as the
image properties will be formatted when adding the image itself which is
not possible without it.

511df17aec cpu_map: Add support for arch-capabilities feature
The feature was added to QEMU in 3.1.0 and it is currently blocking
migration, which is expected to change in the future. Luckily 3.1.0 is
new enough to give us migratability hints on each feature via
query-cpu-model-expension, which means we don't need to use the
"migratable" attribute on the CPU map XML.

The kernel calls this feature arch_capabilities and RHEL/CentOS 7.* use
arch-facilities. Apparently some CPU test files were gathered with the
RHEL version of QEMU. Let's update the test files to avoid possible
confusion about the correct naming.

3dc3e58b32 tests: ignore XML files starting with a .
If an editor has an XML file open, it may create a temporary . file. The
existance of this file will cause the virschematest to fail, so just
skip these editor temp files.

07c9d6601d qemu: use line breaks in command line args written to log
The QEMU command line arguments are very long and currently all written
on a single line to /var/log/libvirt/qemu/$GUEST.log. This introduces
logic to add line breaks after every env variable and "-" optional
argument, and every positional argument. This will create a clearer log
file, which will in turn present better in bug reports when people cut +
paste from the log into a bug comment.

An example log file entry now looks like this:

912c6b22fc util: require command args to be non-NULL
The virCommand APIs do not expect to be given a NULL value for an arg
name or value. Such a mistake can lead to execution of the wrong
command, as the NULL may prematurely terminate the list of args.
Detect this and report suitable error messages.

This identified a flaw in the storage test which was passing a NULL
instead of the volume path. This flaw was then validated by an incorrect
set of qemu-img args as expected data.

4cfd709021 Fix many mistakes & inconsistencies in header file layout
This introduces a syntax-check script that validates header files use a
common layout:

  /*
   ...copyright header...
   */
  <one blank line>
  #ifndef SYMBOL
  # define SYMBOL
  ....content....
  #endif /* SYMBOL */

For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:

  #ifndef SYMBOL_ALLOW
  # error ....
  #endif /* SYMBOL_ALLOW */
  <one blank line>

The many mistakes this script identifies are then fixed.

e6f53e7a4b storage: Fix build issue with MOUNT and VGCHANGE commands
Turns out there some build platforms that must not define MOUNT
or VGCHANGE in config.h... So moving the commands from the storage
backend specific module into a common storage_util module causes
issues for those platforms.

So instead of assuming they are there, let's just pass the command
string to the storage util API's from the storage backend specific
code (as would have been successful before).  Also modify the test
to determine whether the MOUNT and/or VGCHANGE doesn't exist and
just define it to (for example) what Fedora has for the path. Could
have just used "mount" and "vgchange" in the call, but that defeats
the purpose of adding the call to virTestClearCommandPath.

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.

e0eb8a8a69 secret: Add check/validation for correct usage when LookupByUUID
https://bugzilla.redhat.com/show_bug.cgi?id=1656255

If virSecretGetSecretString is using by secretLookupByUUID,
then it's possible the found sec->usageType doesn't match the
desired @secretUsageType. If this occurs for the encrypted
volume creation processing and a subsequent pool refresh is
executed, then the secret used to create the volume will not
be found by the storageBackendLoadDefaultSecrets which expects
to find secrets by VIR_SECRET_USAGE_TYPE_VOLUME.

Add a check to virSecretGetSecretString to avoid the possibility
along with an error indicating the incorrect matched types.
