In msys2 distribution objdump from gcc is using single tab character
prefix, but objdump from clang is using 4 white space characters instead.
The script will not identify any dll dependencies for a QEMU build
generated with clang. This in turn will fail the build, because there
will be no files inside dlldir and no setup file will be created.
Instead of checking for whitespace in prefix use lstrip to accommodate
for differences in outputs.

This tool converts a disk image to qcow2, writing the result directly
to stdout. This can be used for example to send the generated file
over the network.
This is equivalent to using qemu-img to convert a file to qcow2 and
then writing the result to stdout, with the difference that this tool
does not need to create this temporary qcow2 file and therefore does
not need any additional disk space.
Implementing this directly in qemu-img is not really an option because
it expects the output file to be seekable and it is also meant to be a
generic tool that supports all combinations of file formats and image
options. Instead, this tool can only produce qcow2 files with the
basic options, without compression, encryption or other features.
The input file is read twice. The first pass is used to determine
which clusters contain non-zero data and that information is used to
create the qcow2 header, refcount table and blocks, and L1 and L2
tables. After all that metadata is created then the second pass is
used to write the guest data.
By default qcow2-to-stdout.py expects the input to be a raw file, but
if qemu-storage-daemon is available then it can also be used to read
images in other formats. Alternatively the user can also run qemu-nbd
or qemu-storage-daemon manually instead.

create_backend()'s caller catches QAPIError, and returns non-zero exit
code on catch. The caller's caller passes the exit code to
sys.exit().
create_backend() doesn't care: it reports errors to stderr and
sys.exit()s.
Change it to raise QAPIError instead.

Parser and doc generator cooperate on generating stub documentation for
undocumented members. The parser makes up an ArgSection with an empty
description, and the doc generator makes up a description.
Right now, the made-up ArgSections go into doc.args. However, the new
doc generator uses .all_sections, not .args. So put them into
.all_sections, too.
Insert them right after existing 'member' sections. If there are none,
insert directly after the leading section.
Doesn't affect the old generator, because that one doesn't use
.all_sections.

This is for the sake of the new rST generator (the "transmogrifier") so
we can advance multiple lines on occasion while keeping the
generated<-->source mappings accurate.
next_line now simply takes an optional n parameter which chooses the
number of lines to advance.
The next patch will use this when converting section syntax in free-form
documentation to more traditional rST section header syntax, which does
not always line up 1:1 for line counts.
For example:
```
##
# = Section <-- Info is pointing here, "L1"
#
# Lorem Ipsum
##
```
would be transformed to rST as:
```
======= <-- L1
Section <-- L1
======= <-- L1
<-- L2
Lorem Ipsum <-- L3
```
After consuming the single "Section" line from the source, we want to
advance the source pointer to the next non-empty line which requires
jumping by more than one line.

We have several kinds of sections, and to tell them apart, we use
Section attribute @tag and also the section object's Python type:
type @tag
untagged Section None
@foo: ArgSection 'foo'
Returns: Section 'Returns'
Errors: Section 'Errors'
Since: Section 'Since'
TODO: Section 'TODO'
Note:
* @foo can be a member or a feature description, depending on context.
* tag == 'Since' can be a Since: section or a member or feature
description. If it's a Section, it's the former, and if it's an
ArgSection, it's the latter.
Clean this up as follows. Move the member or feature name to new
ArgSection attribute @name, and replace @tag by enum @kind like this:
type kind name
untagged Section PLAIN
@foo: ArgSection MEMBER 'foo' if member or argument
ArgSection FEATURE 'foo' if feature
Returns: Section RETURNS
Errors: Section ERRORS
Since: Section SINCE
TODO: Section TODO
The qapi-schema tests are updated to account for the new section names;
"TODO" becomes "Todo" and `None` becomes "Plain" there.

Instead of using the info object for the doc block as a whole (which
always points to the very first line of the block), update the info
pointer for each call to ensure_untagged_section when the existing
section is otherwise empty. This way, Sphinx error information will
match precisely to where the text actually starts.
For example, this patch will move the info pointer for the "Hello!"
untagged section ...
> ## <-- from here ...
> # Hello! <-- ... to here.
> ##
This doesn't seem to improve error reporting now. It will with the
forthcoming QAPI doc transmogrifier.
If I stick bad rST into qapi/block-core.json like this:
> ##
> # @SnapshotInfo:
> #
> +# rST syntax error: *ahh!
> +#
> # @id: unique shapshot id
> #
> # @name: user chosen name
The existing code's error message will point to the beginning of the doc
comment, which is less than helpful. The transmogrifier's message will
point to the erroneous line, but to accomplish this, it needs this
patch.

This option is supported by both gcc (since 4.7) and clang (since
7.0). Not only does this make the linkers job easier by reducing the
amount of ELF it needs to parse it also reduces the total build size
quite considerably. In my case a default build went from 5.8G to
3.9G (vs 1.9G for --disable-debug-info).
The --disable-split-debug option allows distros to keep all the info
together for ease of packaging.
