docs: mention more about older capability feature bits

Browse Source 
Our documentation for features was rather sparse; this fleshes out
more of the details for other existing capabilities (and cost me
some time trawling git history).

* docs/formatcaps.html.in: Document it feature bits.

with a guest of described type. Possible subelements are:
<dl>
<dt>pae</dt><dd>If present, 32-bit guests can use PAE
address space extensions, <span class="since">since
0.4.1</span></dd>
<dt>nonpae</dt><dd>If present, 32-bit guests can be run
without requiring PAE, <span class="since">since
0.4.1</span></dd>
<dt>ia64_be</dt><dd>If present, IA64 guests can be run in
big-endian mode, <span class="since">since 0.4.1</span></dd>
<dt>acpi</dt><dd>If this element is present,
the <code>default</code> attribute describes whether the
hypervisor exposes ACPI to the guest by default, and
the <code>toggle</code> attribute describes whether the
user can override this
default. <span class="since">Since 0.4.1</span></dd>
<dt>apic</dt><dd>If this element is present,
the <code>default</code> attribute describes whether the
hypervisor exposes APIC to the guest by default, and
the <code>toggle</code> attribute describes whether the
user can override this
default. <span class="since">Since 0.4.1</span></dd>
<dt>cpuselection</dt><dd>If this element is present, the
hypervisor supports the <code>&lt;cpu&gt;</code> element
within a domain definition for fine-grained control over
the CPU presented to the
guest. <span class="since">Since 0.7.5</span></dd>
<dt>deviceboot</dt><dd>If this element is present,
the <code>&lt;boot order='...'/&gt;</code> element can
be used inside devices, rather than the older boot
specification by category. <span class="since">Since
0.8.8</span></dd>
<dt>disksnapshot</dt><dd>If this element is present,
the <code>default</code> attribute describes whether
external disk snapshots are supported. If absent,
external snapshots may still be supported, but it
requires attempting the API and checking for an error to
find out for sure. <span class="since">Since
1.2.3</span></dd>
