The codegen tries to follow the "old" C style and declare loop
iterators at the start of the block / function. Only nested
request handling breaks this style, so adjust it.

Family names may include dashes. Fix notification handling
code gen to the c-compatible name.

If the type for the response to do and dump are the same we don't
generate it twice. This is called "type_consistent" in the generator.
Consider operations which only have dump to also be consistent.
This removes unnecessary "_dump" from the names. There's a number
of GET ops in classic Netlink which only have dump handlers.
Make sure we output the "onesided" types, normally if the type
is consistent we only output it when we render the do structures.

Make sure the codegen calls the right YNL lib helper to start
the request based on family type. Classic netlink request must
not include the genl header.
Conversely don't expect genl headers in the responses.

C codegen skips generating the structs if request/reply has no attrs.
In such cases the request op takes no argument and return int
(rather than response struct). In case of classic netlink a lot of
information gets passed using the fixed struct, however, so adjust
the logic to consider a request empty only if it has no attrs _and_
no fixed struct.

Classic netlink has static family IDs specified in YAML,
there is no family name -> ID lookup. Support providing
the ID info to the library via the generated struct and
make library use it. Since NETLINK_ROUTE is ID 0 we need
an extra boolean to indicate classic_id is to be used.

_decode_array_attr() uses variable subattrs in every branch when only
one branch decodes more than a single attribute.
Change the variable name to subattr in the branches that only decode a
single attribute so that the intent is more obvious.

A definition with a "header" property is an "external" definition
for C code, as in it is defined already in another C header file.
Other languages will need the exact value but C codegen should
not recreate it. So don't output those definitions in the uAPI
header.

Also rename ynl-gen-[c|rst] to ynl_gen_[c|rst], avoid
dashes as these prevent easy imports for entrypoints.
