When a sub-module doesn't contain any definitions, we don't generate
code for it, but we do generate the #include.
We generate code only for modules that get visited.
QAPISchema.visit() visits only modules that have definitions. It can
visit modules multiple times.
Clean this up as follows. Collect entities in their QAPISchemaModule.
Have QAPISchema.visit() call QAPISchemaModule.visit() for each module.
Have QAPISchemaModule.visit() call .visit_module() for itself, and
QAPISchemaEntity.visit() for each of its entities. This way, we visit
each module exactly once.

Modules are represented only by their names so far. Introduce class
QAPISchemaModule. So far, it merely wraps the name. The next patch
will put it to more interesting use.
Once again, arrays spice up the patch a bit. For any other type,
@info points to the definition, which lets us map from @info to
module. For arrays, there is no definition, and @info points to the
first use instead. We have to use the element type's module instead,
which is only available after .check().

Surprisingly, QEMU does have a pretty consistent doc comment style and
it is not very different from the Linux kernel's. Of the documentation
"sigils", only "#" separates the QEMU doc comment style from Linux's,
and it has 200+ instances vs. 6 for the kernel's '&struct foo' (all in
accel/tcg/translate-all.c), so it's clear that the two standards are
different in this respect. In addition, our structs are typedefed and
recognized by CamelCase names.
Adjust kernel-doc's parser for these two aspects of the QEMU coding
standards. The patch has been valid, with hardly any change, for over
two years, so it should not be an issue to keep kernel-doc in sync with
the Linux copy.

the QEMU source tree root. The extension also notifies Sphinx about the

When a command's 'data' is an object, its doc comment describes the
arguments defined there. When 'data' names a type, the doc comment
does not describe arguments. Instead, the doc generator inserts a
pointer to the named type.
An event's doc comment works the same.
We don't actually check doc comments for commands and events.
Instead, QAPISchema._def_command() forwards the doc comment to the
implicit argument type, where it gets checked. Works because the
check only cares for the implicit argument type's members.
Not only is this needlessly hard to understand, it actually falls
apart in two cases:
* When 'data' is empty, there is nothing to forward to, and the doc
comment remains unchecked. Demonstrated by test doc-bad-event-arg.
* When 'data' names a type, we can't forward, as the type has its own
doc comment. The command or event's doc comment remains unchecked.
Demonstrated by test doc-bad-boxed-command-arg.
The forwarding goes back to commit 069fb5b250 "qapi: Prepare for
requiring more complete documentation", put to use in commit
816a57cd6e "qapi: Fix detection of bogus member documentation". That
fix was incomplete.
To fix this, make QAPISchemaCommand and QAPISchemaEvent check doc
comments, and drop the forwarding of doc comments to implicit argument
types.

An object type's doc comment describes the type's members, less the
ones defined in a named base type. Cases:
* Struct: the members are defined in 'data' and inherited from 'base'.
Since the base type cannot be implicit, the doc comment describes
just 'data'.
* Simple union: the only member is the implicit tag member @type, and
the doc comment describes it.
* Flat union with implicit base type: the members are defined in
'base', and the doc comment describes it.
* Flat union with named base type: the members are inherited from
'base'. The doc comment describes no members.
Before we can check a doc comment with .check_doc(), we need
.connect_doc() connect each of its "argument sections" to the member
it documents.
For structs and simple unions, this is straightforward: the members in
question are in .local_members, and .connect_doc() connects them.
For flat unions with a named base type, it's trivial: .local_members
is empty, and .connect_doc() does nothing.
For flat unions with an implicit base type, it's tricky. We have
QAPISchema._make_implicit_object_type() forward the union's doc
comment to the implicit base type, so that the base type's
.connect_doc() connects the members. The union's .connect_doc() does
nothing, as .local_members is empty.
Dirt effect: we check the doc comment twice, once for the union type,
and once for the implicit base type.
This is needlessly brittle and hard to understand. Clean up as
follows. Make the union's .connect_doc() connect an implicit base's
members itself. Do not forward the union's doc comment to its
implicit base type.
Requires extending .connect_doc() so it can work with a doc comment
other than self.doc. Add an optional argument for that.

The next commit will split up qapi/common.py. gen_enum() needs
QAPISchemaEnumMember, and that's in the way. Move it to qapi/types.py

Permit me a short a digression on history: how did gen_enum() end up
in qapi/common.py? Commit 21cd70dfc1 "qapi script: add event support"
duplicated qapi-types.py's gen_enum() and gen_enum_lookup() in
qapi-event.py. Simply importing them would have been cleaner, but
wasn't possible as qapi-types.py was a program, not a module. Commit
efd2eaa6c2 "qapi: De-duplicate enum code generation" de-duplicated by
moving them to qapi.py, which was a module.
Since then, program qapi-types.py has morphed into module types.py.

belong.

The `make efi` target added by 536d2173 is built from the roms/edk2
submodule, which in turn relies on additional submodules nested under
roms/edk2.
The make-release script currently only pulls in top-level submodules,
so these nested submodules are missing in the resulting tarball.
We could try to address this situation more generally by recursively
pulling in all submodules, but this doesn't necessarily ensure the
end-result will build properly (this case also required other changes).
Additionally, due to the nature of submodules, we may not always have
control over how these sorts of things are dealt with, so for now we
continue to handle it on a case-by-case in the make-release script.

The low bits are 1 if the control must be one, the high bits
are 1 if the control can be one. Correct the variable names
as they are very confusing.

qapi-gen.py crashes when it can't open the main schema file, and when
it can't read from any schema file. Lazy.
Change QAPISchema.__init__() to take a file name instead of a file
object. Move the open code from _include() to __init__(), so it's
used for the main schema file, too.
Move the read into the try for good measure, and rephrase the error
message.
Reporting open or read failure for the main schema file needs a
QAPISourceInfo representing "no source". Make QAPISourceInfo cope
with fname=None.

Have check_exprs() check this later, so the error message gains an "in
definition line". Tweak the error message.

check_keys() has become a trivial wrapper for check_known_keys().
Eliminate it.
This makes its name available. Rename check_known_keys().

check_if()'s errors don't point to the offending part of the
expression. For instance:
tests/qapi-schema/alternate-branch-if-invalid.json:2: 'if' condition ' ' makes no sense
Other check_FOO() do, with the help of a @source argument. Make
check_if() do that, too. The example above improves to:
tests/qapi-schema/alternate-branch-if-invalid.json:2: 'if' condition ' ' of 'data' member 'branch' makes no sense
