Implement the ability of marking some versions deprecated. When
that CPU model is chosen, print a warning. The warning message
can be customized, e.g. suggesting an alternative CPU model to be
used instead.
The deprecation message will be printed by x86_cpu_list_entry(),
e.g. '-cpu help'.
QMP command 'query-cpu-definitions' will return a bool value
indicating the deprecation status.

[ehabkost: Handle NULL cpu_type]
Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
The various schemas included in QEMU use a JSON-based format which
is, however, strictly speaking not valid JSON.
As a consequence, when vim tries to apply syntax highlight rules
for JSON (as guessed from the file name), the result is an unreadable
mess which mostly consist of red markers pointing out supposed errors
in, well, pretty much everything.
Using Python syntax highlighting produces much better results, and
in fact these files already start with specially-formatted comments
that instruct Emacs to process them as if they were Python files.
This commit adds the equivalent special comments for vim.

The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.
Make the doc comments more strongly consistent about indentation
for multiline constructs like:
@arg: description line 1
description line 2
Returns: line one
line 2
so that there is always exactly one space after the colon, and
subsequent lines align with the first.
This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace). This does mean that we end up with some
over-length lines.
Note that when the documentation for an argument fits on a single
line like this:
@arg: one line only
then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

Add support for the query-cpu-model-expansion QMP command to Arm. We
do this selectively, only exposing CPU properties which represent
optional CPU features which the user may want to enable/disable.
Additionally we restrict the list of queryable cpu models to 'max',
'host', or the current type when KVM is in use. And, finally, we only
implement expansion type 'full', as Arm does not yet have a "base"
CPU type. More details and example queries are described in a new
document (docs/arm-cpu-features.rst).
Note, certainly more features may be added to the list of advertised
features, e.g. 'vfp' and 'neon'. The only requirement is that we can
detect invalid configurations and emit failures at QMP query time.
For 'vfp' and 'neon' this will require some refactoring to share a
validation function between the QMP query and the CPU realize
functions.

Move commands query-cpu-definitions, query-cpu-model-baseline,
query-cpu-model-comparison, and query-cpu-model-expansion with their
types from target.json to machine-target.json. Also move types
CpuModelInfo, CpuModelExpansionType, and CpuModelCompareResult from
misc.json there. Add machine-target.json to MAINTAINERS section
"Machine core".
