dd044023e6 tests/qapi-schema: Demonstrate broken C code for 'if'
The C code generated for 'if' conditionals is incorrectly
parenthesized.  For instance,

    'if': { 'not': { 'any': [ { 'not': 'TEST_IF_EVT' },
			      { 'not': 'TEST_IF_STRUCT' } ] } } }

generates

    #if !(!defined(TEST_IF_EVT)) || (!defined(TEST_IF_STRUCT))

This is wrong.  Correct would be:

    #if !(!defined(TEST_IF_EVT) || !defined(TEST_IF_STRUCT))

Cover the issue in qapi-schema-test.json.  This generates bad #if in
tests/test-qapi-events.h and other files.

Add a similar condition to doc-good.json.  The generated documentation
is fine.

8a9f1e1d9c qapi: make 'if' condition strings simple identifiers
Change the 'if' condition strings to be C-agnostic. It will accept
'[A-Z][A-Z0-9_]*' identifiers. This allows to express configuration
conditions in other languages (Rust or Python for ex) or other more
suitable forms.

b09c8f7a99 tests/qapi-schema: Convert doc-good.json to rST-style strong/emphasis
doc-good.json currently uses the old *strong* and _emphasis_ markup.
As part of the conversion to rST this needs to switch to **strong**
and *emphasis*, because rST uses underscores as part of its markup
of hyperlinks and will otherwise warn about the syntax error.

In commit a660eed482 we fixed up the in-tree uses of the
old markup:
 1) _this_ was replaced with *this*
 2) the only in-tree use of *this* was left alone (turning
    a 'strong' into an 'emphasis')
(and so currently in-tree nothing is using either new-style
**strong** or old-style _emphasis_).

Update doc-good.json in a similar way:
 1) replace _this_ with *this*
 2) remove the usage of old-style *this*

(This slightly reduces the coverage for the old Texinfo generator,
which is about to go away, but is fine for the new rST generator
because that does not need to handle strong/emphasis itself because
it is simply passing the entire text as raw rST to Sphinx.)

63a97cf5a0 tests/qapi/doc-good.json: Prepare for qapi-doc Sphinx extension
doc-good.json tests doc comment parser corner cases.  We're about to
largely replace it by a Sphinx extension, which will have different
corner cases.  Tweak the test so it passes both with the old parser
and the Sphinx extension, by making it match the more restrictive
rST syntax:

 * in a single list the bullet types must all match
 * lists must have leading and following blank lines
 * the rules on when and where indentation matters differ
 * the '|' example syntax is going to go away entirely, so stop
   testing it

This will avoid the tests spuriously breaking when we tighten up the
parser code in the following commits.

f7160f3218 schemas: Add vim modeline
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.

013b4efc9b qapi: Add feature flags to remaining definitions
In v4.1.0, we added feature flags just to struct types (commit
6a8c0b5102^..f3ed93d545), to satisfy an immediate need (commit
c9d4070991 "file-posix: Add dynamic-auto-read-only QAPI feature").  In
v4.2.0, we added them to commands (commit 23394b4c39 "qapi: Add
feature flags to commands") to satisfy another immediate need (commit
d76744e65e "qapi: Allow introspecting fix for savevm's cooperation
with blockdev").

Add them to the remaining definitions: enumeration types, union types,
alternate types, and events.

Update positive test doc-good to cover boxed event arguments.  It
