The tutorial doesn't match reality since at least 2013. Repairing it
involves fixing the following issues:
* Update for commit 6d327171551 (aio / timers: Remove alarm timers):
replace the broken examples. Instead of having one for returning a
struct and another for returning a list of structs, do just one for
the latter. This resolves the FIXME added in commit
e218052f928 (aio / timers: De-document -clock) back in 2014.
* Update for commit 895a2a80e0e (qapi: Use 'struct' instead of 'type'
in schema).
* Update for commit 3313b6124b5 (qapi: add qapi2texi script): add
required documentation to the schema snippets, and drop section
"Command Documentation".
* Update for commit a3c45b3e629 (qapi: New special feature flag
"unstable"): supply the required feature, deemphasize the x- prefix.
* Update for commit dd98234c059 (qapi: introduce x-query-roms QMP
command): rephrase from "add new command" to "examine existing
command".
* Update for commit 9492718b7c0 (qapi misc: Elide redundant has_FOO in
generated C): hello-world's message argument no longer comes with a
has_message, add a second argument that does.
* Update for moved and renamed files.
While there, update QMP version output to current output.
