for icount behaviour into one reference document for our developer
notes.

qapi: Disallow qmp_marshal_FOO(NULL, ...)
For QMP commands without arguments, gen_marshal() laboriously
generates a qmp_marshal_FOO() that copes with null @args. Turns
there's just one caller that passes null instead of an empty QDict.
Adjust that caller, and simplify gen_marshal().

atomics: update documentation
Some of the constraints on operand sizes have been relaxed, so adjust the
documentation.
Deprecate atomic_mb_read and atomic_mb_set; it is not really possible to
use them correctly because they do not interoperate with sequentially-consistent
RMW operations.
Finally, extend the memory barrier pairing section to cover acquire and
release semantics in general, roughly based on the KVM Forum 2016 talk,
"<atomic.h> weapons".

qapi: New special feature flag "deprecated"
Unlike regular feature flags, the new special feature flag
"deprecated" is recognized by the QAPI generator. For now, it's only
permitted with commands, events, and struct members. It will be put
to use shortly.

qapi: Add feature flags to remaining definitions
In v4.1.0, we added feature flags just to struct types (commit
6a8c0b5102^..f3ed93d545), to satisfy an immediate need (commit
c9d4070991 "file-posix: Add dynamic-auto-read-only QAPI feature"). In
v4.2.0, we added them to commands (commit 23394b4c39 "qapi: Add
feature flags to commands") to satisfy another immediate need (commit
d76744e65e "qapi: Allow introspecting fix for savevm's cooperation
with blockdev").
Add them to the remaining definitions: enumeration types, union types,
alternate types, and events.
