3a43ded081 tools: ynl: store ops in ordered dict to avoid random ordering
When rendering code we should walk the ops in the order in which
they are declared in the spec. This is both more intuitive and
prevents code from jumping around when hashing in the dict changes.

b49c34e217 tools: ynl: rename ops_list -> msg_list
ops_list contains all the operations, but the main iteration use
case is to walk only ops which define attrs. Rename ops_list to
msg_list, because now it looks like the contents are the same,
just the format is different. While at it convert from tuple
to just keys, none of the users care about the name of the op.

66fa34b9c2 tools: ynl: support kdocs for flags in code generation
Lorenzo reports that after switching from enum to flags netdev
family lost ability to render kdoc (and the enum contents got
generally garbled).

Combine the flags and enum handling in uAPI handling.

e4b48ed460 tools: ynl: add a completely generic client
Add a CLI sample which can take in arbitrary request
in JSON format, convert it to Netlink and do the inverse
for output.

It's meant as a development tool primarily and perhaps
for selftests which need to tickle netlink in a special way.

be5bea1cc0 net: add basic C code generators for Netlink
Code generators to turn Netlink specs into C code.
I'm definitely not proud of it.

The main generator is in Python, there's a bash script
to regen all code-gen'ed files in tree after making
spec changes.
