Peter Maydell 100cc4fe0f qapi: Add blank lines before bulleted lists
We would like to switch the doc comments to rST format. rST
insists on a blank line before and after a bulleted list, but our
Texinfo doc generator did not. Add some extra blank lines in the doc
comments so they're acceptable rST input.

Peter Maydell 26ec4e53f2 qapi: Fix indent level on doc comments in json files
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.

Markus Armbruster f5cf31c575 qapi-schema: Improve section headings
The generated QEMU QMP reference is now structured as follows:

    1.1 Introduction
    1.2 Stability Considerations
    1.3 Common data types
    1.4 Socket data types
    1.5 VM run state
    1.6 Cryptography
    1.7 Block devices
    1.7.1 Block core (VM unrelated)
    1.7.2 QAPI block definitions (vm unrelated)
    1.8 Character devices
    1.9 Net devices
    1.10 Rocker switch device
    1.11 TPM (trusted platform module) devices
    1.12 Remote desktop
    1.12.1 Spice
    1.12.2 VNC
    1.13 Input
    1.14 Migration
    1.15 Transactions
    1.16 Tracing
    1.17 QMP introspection
    1.18 Miscellanea

Section "1.18 Miscellanea" is still too big: it documents 134 symbols.
Section "1.7.1 Block core (VM unrelated)" is also rather big: 128
symbols.  All the others are of reasonable size.

Markus Armbruster 1d8bda128d qapi: The #optional tag is redundant, drop
We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.

Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional.  This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out.  We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.

Thus, you can't actually rely on #optional to see whether something is
optional.  Yet we still make people add it manually.  That's just
busy-work.

Drop the code to check, fix up and strip out #optional, along with all
instances of #optional.  To keep it out, add code to reject it, to be
dropped again once the dust settles.

No change to generated documentation.

Eric Blake 895a2a80e0 qapi: Use 'struct' instead of 'type' in schema
Referring to "type" as both a meta-type (built-in, enum, union,
alternate, or struct) and a specific type (the name that the
schema uses for declaring structs) is confusing.  Do the bulk of
the conversion to "struct" in qapi schema, with a fairly
mechanical:

for f in `find -name '*.json'; do sed -i "s/'type'/'struct'/"; done

followed by manually filtering out the places where we have a
'type' embedded in 'data'.  Then tweak a couple of tests whose
output changes slightly due to longer lines.

I also verified that the generated files for QMP and QGA (such
as qmp-commands.h) are the same before and after, as assurance
that I didn't leave in any accidental member name changes.
