Migration compression parameters 'compress-level', 'compress-threads',

Note that the migration code automatically checks whether given
capability is supported by qemu and thus we don't need to add any

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")

Xcode 15, which provides the compiler toolchain for building libvirt
on macOS has switched to a new linker that warns about duplicated
"-lblah" options on the ld commandline. In practice this is impossible
to prevent in a large project, and also harmless.
Fortunately the new ld command also has an option,
-no_warn_duplicate_libraries, that supresses this harmless/pointless
warning, meson has a simple way to check if that option is supported,
and libvirt's meson.build files already have examples of adding an
option to the ld commandline if it's available.

Currently some, but not all, methods have a call to the
xdr_free function, for the 'ret' variable. This is done
on methods where there are complex structs containing
allocated memory. In other cases the structs contain
allocated memory, but the pointer is stolen, so xdr_free
is not called. In other cases no allocated memory is
present, so xdr_free.
This is hard to reason about, because the definition of
the struct is not visible in the client stubs.
Switch to use g_auto() for the 'ret' variable, which
means 'xdr_free' is always going to be called. Some
places now need to use g_steal_pointer as a result.

The new program takes the form
rpcgen [--mode source|header|repr] \
[--header include] \
xdr-file output-file
If '--mode' is not given it parses the XDR file but does not
generate anything, which is useful as a syntax check. The
'source' mode gives the '.c' file content, while 'header'
gives the '.h' file content. 'repr' gives a representation
of the abstract syntax tree, mostly useful for debugging
the parser.
If '--header' is given, it is added as a local #include ".."
statement in the output and is valid for either 'header'
or 'source' modes.
Either 'xdr-file' or 'output-file' can be omitted in which
case they default to stdin/stdout respectively.
This rpcgen program will directly include the 'config.h'
header in its 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.

as it is intended to be an opinionated formatting tool
standardizing python code style, and thus not to be

The flake8 check E203 does not want whitespace before
a ':'. This is, however, desirable when indexing array
slices eg
self.lookahead[skip : skip + 1]
which is a format that 'black' produces.

The current RPC code is post-processed to introduce an
intermediate variable, rather than casting directly
to char ** at time of use. This is said to be a workaround
for type-puning warnings that the compiler emitted.
Neither GCC or CLang emit any warnings for the code in
question today, across any of the architectures we
test in CI. Thus it is presumed that somewhere in the
15 years since the workaround was done, the compilers
have got smarter and do the right thing.

This environment variable is supposedly set according to the contents
of ~/.CFUserTextEncoding, and certainly on MacOS 14 (Sonoma) it is set
in the environment of child processes created by execve() (used by
virCommand()), causing commandtest to fail. (However, the value that is
shown in $__CF_USER_TEXT_ENCODING during the test 1) is not in the
environment of the shell the test is run from, and 2) doesn't match
the contents of ~/.CFUserTextEncoding.)
It is true, though, that filtering out this environment setting from
the test results permits commandtest to pass on macOS 14 (Sonoma).
