Since commit 5d83b9a130 "qapi: replace if condition list with dict
{'all': [...]}", we represent if conditionals as trees consisting of
OrderedDict, list and str. This results in less than legible test
output. For instance:
if OrderedDict([('not', OrderedDict([('any', [OrderedDict([('not', 'TEST_IF_EVT')]), OrderedDict([('not', 'TEST_IF_STRUCT')])])]))])
We intend to replace OrderedDict by dict when we get Python 3.7, which
will result in more legible output:
if {'not': {'any': [{'not': 'TEST_IF_EVT'}, {'not': 'TEST_IF_STRUCT'}]}}
Can't wait: put in a hack to get that now, with a comment to revert it
when we replace OrderedDict.

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.

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.)

Make the handling of indentation in doc comments more sophisticated,
so that when we see a section like:
Notes: some text
some more text
indented line 3
we save it for the doc-comment processing code as:
some text
some more text
indented line 3
and when we see a section with the heading on its own line:
Notes:
some text
some more text
indented text
we also accept that and save it in the same form.
If we detect that the comment document text is not indented as much
as we expect it to be, we throw a parse error. (We don't complain
about over-indented sections, because for rST this can be legitimate
markup.)
The golden reference for the doc comment text is updated to remove
the two 'wrong' indents; these now form a test case that we correctly
stripped leading whitespace from an indented multi-line argument
definition.
We update the documentation in docs/devel/qapi-code-gen.txt to
describe the new indentation rules.

[Whitespace between sentences tweaked]
Signed-off-by: Markus Armbruster <armbru@redhat.com>
As we accumulate lines from doc comments when parsing the JSON, the
QAPIDoc class generally strips leading and trailing whitespace using
line.strip() when it calls _append_freeform(). This is fine for
Texinfo, but for rST leading whitespace is significant. We'd like to
move to having the text in doc comments be rST format rather than a
custom syntax, so move the removal of leading whitespace from the
QAPIDoc class to the texinfo-specific processing code in
texi_format() in qapi/doc.py.
(Trailing whitespace will always be stripped by the rstrip() in
Section::append regardless.)
In a followup commit we will make the whitespace in the lines of doc
comment sections more consistently follow the input source.
There is no change to the generated .texi files before and after this
commit.
Because the qapi-schema test checks the exact values of the
documentation comments against a reference, we need to update that
reference to match the new whitespace. In the first four places this
is now correctly checking that we did put in the amount of whitespace
to pass a rST-formatted list to the backend; in the last two places
the extra whitespace is 'wrong' and will go away again in the
following commit.

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.

Our current QAPI doc-comment markup allows section headers (introduced
with a leading '=' or '==') anywhere in a free-form documentation
comment. This works for Texinfo because the generator simply prints a
Texinfo section command at that point in the output stream. For rST
generation, since we're assembling a tree of docutils nodes, this is
awkward because a new section implies starting a new section node at
the top level of the tree and generating text into there.
Make section headers start a new free-form documentation block, so the
future rST document generator doesn't have to look at every line in
free-form blocks and handle headings in odd places.
This change makes no difference to the generated Texinfo.

We neglect to call .visit_module() for the special module we use for
built-ins. Harmless, but clean it up anyway. The
tests/qapi-schema/*.out now show the built-in module as 'module None'.
Subclasses of QAPISchemaModularCVisitor need to ._add_module() this
special module to enable code generation for built-ins. When this
hasn't been done, QAPISchemaModularCVisitor.visit_module() does
nothing for the special module. That looks like built-ins could
accidentally be generated into the wrong module when a subclass
neglects to call ._add_module(). Can't happen, because built-ins are
all visited before any other module. But that's non-obvious. Switch
off code generation explicitly.

The include directive permits modular QAPI schemata, but the generated
code is monolithic all the same. To permit generating modular code,
the front end needs to pass more information on inclusions to the back
ends. The commit before last added the necessary information to the
parse tree. This commit adds it to the intermediate representation
and its QAPISchemaVisitor. A later commit will use this to to
generate modular code.
New entity QAPISchemaInclude represents inclusions. Call new visitor
method visit_include() for it, so visitors can see the sub-modules a
module includes.
Note that unlike other entities, QAPISchemaInclude has no name, and is
therefore not added to entity_dict.
New QAPISchemaEntity attribute @module names the entity's source file.
Call new visitor method visit_module() when it changes during a visit,
so visitors can keep track of the module being visited.
