[PULL 3/8] contrib/plugins/execlog: Add tab to the separator search of insn_disas

[Alex Bennée]

From: Yodel Eldar <yodel.eldar@gmail.com>

Currently, execlog searches for a space separator between the
instruction mnemonic and operands, but some disassemblers, e.g. Alpha's,
use a tab separator instead; this results in a null pointer being passed
as the haystack in g_strstr during a subsequent register search, i.e.
undefined behavior, because of a missing null check.

This patch adds tab to the separator search and a null check on the
result.

Also, an affected pointer is changed to const.

Lastly, a break statement was added to immediately terminate the
register search when a user-requested register is found in the current
instruction as a trivial optimization, because searching for the
remaining requested registers is unnecessary once one is found.

[PULL 5/8] plugins: fix inclusion of user-mode APIs

[Alex Bennée]

In 903e870f24 (plugins/api: split out binary path/start/end/entry
code) we didn't actually enable the building of the new plugin helper.
However this was missed because only contrib plugins like drcov
actually used the helpers.

With that fixed we discover we also need some more includes to be able
to extract the relevant data from TaskState.

Fixes: 903e870f24 (plugins/api: split out binary path/start/end/entry code)

[PULL 6/8] docs: use :kbd: role in sphinx docs

[Alex Bennée]

From: Manos Pitsidianakis <manos.pitsidianakis@linaro.org>

Sphinx supports the :kbd: role for notating keyboard input. They get
formatted as <kbd> HTML elements in the readthedocs theme we currently
use for Sphinx.

Besides the better visual formatting, it also helps with accessibility
as screen readers can announce the semantics of the <kbd> element to the
user.

[PULL 7/8] docs/system: clean-up formatting of virtio-net-failover

[Alex Bennée]

We didn't clean-up the rst formatting when we moved this into the
docs so lets do that now:

 - un-indent the usage/hotplug/migration paragraphs
 - properly wrap the command line fragments in code-block
 - highlight parameters in text with ``double quotes``

No changes to the actual text.

 Usecase

-  Virtio-net standby allows easy migration while using a passed-through fast
