550bf7682d kbase: Document how to disable Secure Boot entirely
In most cases, disabling the secure-boot or the enrolled-keys
firmware feature will achieve the same result: allowing an
unsigned operating system to run.

Right now we're only documenting the latter configuration. Add
the former as well, and explain the difference between the two.

18249f278a kbase: Always explicitly enable secure-boot firmware feature
It should be enough to enable or disable the enrolled-keys feature
to control whether Secure Boot is enforced, but there's a slight
complication: many distro packages for edk2 include, in addition
to general purpose firmware images, builds that are targeting the
Confidential Computing use case.

For those, the firmware descriptor will not advertise the
enrolled-keys feature, which will technically make them suitable
for satisfying a configuration such as

  <os firmware='efi'>
    <firmware>
      <feature state='off' name='enrolled-keys'/>
    </firmware>
  </os>

In practice, users will expect the general purpose build to be
used in this case. Explicitly asking for the secure-boot feature
to be enabled achieves that result at the cost of some slight
additional verbosity.

e6c29f09e5 conf: Add support for specifying CPU max physical address size
This patch introduces the

    <maxphysaddr mode='passthrough'/>
    <maxphysaddr mode='emulate' bits='42'/>

sub element of /domain/cpu, which allows specifying the guest virtual CPU
address size. This can be useful if the guest needs to have a large amount
of memory.

If mode='passthrough', the virtual CPU will have the same number of address
bits as the host. If mode='emulate', the mandatory bits attribute specifies
the number of address bits.

578ac25c6a conf: support stateless UEFI firmware
Normally when an UEFI firmware is marked as read-only, an associated
NVRAM file will be created. Some builds of UEFI firmware, however, wish
to remain stateless and so will be read-only, but never have any NVRAM
file. To represent this concept a 'stateless' tristate bool attribute
is introduced on the <loader/> element.

There are rather a large number of permutations to consider.

With default firmware selection

  *  <os/>

     => Historic default, no change

  *  <os>
       <loader stateless='yes'/>
     </os>

     => Explicit version of historic default, no change

  *  <os>
       <loader stateless='no'/>
     </os>

      => Invalid, bios is always stateless

With manual legacy BIOS selection

  *  <os>
       <loader>/path/to/seabios</loader>
       ...
     </os>

     => Historic default, no change

  *  <os>
       <loader stateless='yes'>/path/to/seabios</loader>
       ...
     </os>

     => Explicit version of historic default, no change

  *  <os>
       <loader stateless='no'>/path/to/seabios</loader>
       ...
     </os>

      => Invalid, bios is always stateless

With manual UEFI selection

  *  <os>
       <loader type='pflash'>/path/to/edk2</loader>
       ...
     </os>

     => Historic default, no change

  *  <os>
       <loader type='pflash' stateless='yes'>/path/to/edk2</loader>
       ...
     </os>

     => Skip auto-filling NVRAM / template

  *  <os>
       <loader type='pflash' stateless='no'>/path/to/edk2</loader>
       ...

32b9d4390e coding-style: Allow some use of ternary operators
While we all understand that excessive use of ternary operator
may worsen code readability (e.g. nested, multi-line expression),
there are few cases where using it actually improves code
readability. For instance, when a function takes a long list of
arguments out of which one depends on a boolean expression, or
when formatting "yes"/"no" or "on"/"off" values based on a
boolean variable (although one can argue that the latter is a
subset of the former). Just consider alternatives to:

  virBufferAsprintf(buf, "<elem>%s</elem>\n", boolVar ? "yes" : "no");

In fact, this pattern occurs plenty in our code. Exempt it from
our "no ternary operators" rule.

8603b3d76c tools: add '--xpath EXPRESSION --wrap' args to all dumpxml commands
While you can chain the virsh output up to a later 'xmllint' or 'xpath'
command, integrating it into virsh avoids needs for installing extra
binaries which we've often found to be missing on production installs
of libvirt. It also gives better response if the initial virsh command
hits an error, as you don't get an aborted pipeline.

    $ virsh pool-dumpxml --xpath //permissions default
    <permissions>
      <mode>0711</mode>
      <owner>1000</owner>
      <group>1000</group>
      <label>unconfined_u:object_r:svirt_home_t:s0</label>
    </permissions>

If multiple nodes match, they are emitted individually:

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
    <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>

    <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>

but if intending to post-process the output further, the results
can be wrapped in a parent node

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <nodes>
      <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>

3299e00298 docs: domain: Remove extraneous quotes
Certain documentation bits tried to put a reference of a value into
quotes, but that's not needed for both the pure view of the rST source

8452124669 docs: Add HTML reference checker
In many cases we move around or rename internal anchors which may break
links leading to the content.

docutils handle the case of links inside a document, but we are lacking
the same form of checking between documents.

Introduce a script which cross-checks all the anchors and links in HTML
output files and prints problems and use it as a test case for the
'docs' directory.
