When parsing an XML it may be important to keep indentation to
produce a better looking result when formatting the XML back.
Just look at all those xmlKeepBlanksDefault() calls just before
virXMLParse() is called.
Anyway, as of libxml2 commit v2.12.0~108 xmlKeepBlanksDefault()
is deprecated. Therefore, introduce virXMLParse...WithIndent()
variants which would do exactly xmlKeepBlanksDefault() did but
with non-deprecated APIs.

As mentioned in previous commit, VirtualBox has its own snapshot
XML which we parse, change and then format back. During this, we
ought to keep the indentation to produce better looking result
(especially when we want to compare the output in tests later on,
like we do in vboxsnapshotxmltest).

When working with VirtualBox's snapshots, the snapshot XML is
firstly parsed, stored in memory (with some parts being stored as
verbatim XML snippets, strings), requested changes are made and
then this modified XML is formatted via
virVBoxSnapshotConfSaveVboxFile() which calls
xmlParseInNodeContext() to format those previously stored XML
snippets.
The first parse of whole VirtualBox snapshot file is done using
virXMLParse() (in virVBoxSnapshotConfLoadVboxFile()) and thus
with XML_PARSE_NONET specified.
But those ad-hoc parsings when formatting the XML back pass zero
flags mask: xmlParseInNodeContext(..., options = 0, ...);
This is potentially dangerous.

flake8 (run on all python scripts as a part of the syntax checks)

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.

This is hard to reason about, because the definition of

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.

- 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.
