flake8 (run on all python scripts as a part of the syntax checks)
version 6.1.0 (on macOS 14) issued many complaints like this on the
new rpcgen python scripts:
[...]libvirt/scripts/rpcgen/rpcgen/lexer.py:57:17: E721 do not compare types, for exact checks use `is` / `is not`, for instance checks use `isinstance()`
This patch changes all [type] == [type] to use "is" instead of "==",
and similarly to use "is not" instead of "!=".
(flake8 5.03, e.g. on Fedora 38, is just fine with using "==" and "!=",
but python on both likes "is" and "is not")

This replaces use of 'rpcgen' with our new python impl of
the RPC code generator. Since the new impl generates code
that matches our style/coding rules, and does not contain
long standing bugs, we no longer need to post-process the
output.

This implements a C code generator that emits code that is
(almost) identical to the classic 'rpcgen' program. The
key differences are:
- Skip inlining of calls for struct fields
- Skip K&R style function prototypes in headers
- Use int64_t instead of quad_t for OS portability
- Saner whitespace / indentation
The tests/demo.c and tests/demo.h files were created using
the traditional 'rpcgen' program, and then editted to cut
out the leading boilerplate, and the differences mentioned
above.
