We have a very frequent pattern of creating a coroutine from a function
with several arguments:
- create a structure to pack parameters
- create _entry function to call original function taking parameters
from struct
- do different magic to handle completion: set ret to NOT_DONE or
EINPROGRESS or use separate bool field
- fill the struct and create coroutine from _entry function with this
struct as a parameter
- do coroutine enter and BDRV_POLL_WHILE loop
Let's reduce code duplication by generating coroutine wrappers.
This patch adds scripts/block-coroutine-wrapper.py together with some
friends, which will generate functions with declared prototypes marked
by the 'generated_co_wrapper' specifier.
The usage of new code generation is as follows:
1. define the coroutine function somewhere
int coroutine_fn bdrv_co_NAME(...) {...}
2. declare in some header file
int generated_co_wrapper bdrv_NAME(...);
with same list of parameters (generated_co_wrapper is
defined in "include/block/block.h").
3. Make sure the block_gen_c declaration in block/meson.build
mentions the file with your marker function.
Still, no function is now marked, this work is for the following
commit.

https://www.youtube.com/watch?v=YAdRf_hwxU8 (video)
https://vmsplice.net/~stefan/stefanha-kvm-forum-2018.pdf (slides)
This patch adds a guide to secure coding practices. This document
covers things that developers should know about security in QEMU. It is
just a starting point that we can expand on later. I hope it will be
useful as a resource for new contributors and will save code reviewers
from explaining the same concepts many times.

By default Sphinx wants to build a single manual at once.
For QEMU, this doesn't suit us, because we want to have
separate manuals for "Developer's Guide", "User Manual",
and so on, and we don't want to ship the Developer's Guide
to end-users. However, we don't want to completely duplicate
conf.py for each manual, and we'd like to continue to
support "build all docs in one run" for third-party sites
like readthedocs.org.
Make the top-level conf.py support two usage forms:
(1) as a common config file which is included by the conf.py
for each of QEMU's manuals: in this case sphinx-build is run
multiple times, once per subdirectory.
(2) as a top level conf file which will result in building all
the manuals into a single document: in this case sphinx-build is
run once, on the top-level docs directory.
Provide per-manual conf.py files and top level pages for
our first two manuals:
* QEMU Developer's Guide (docs/devel)
* QEMU System Emulation Management and Interoperability Guide
(docs/interop)
