Philip Withnall 5054b48b7c gdbusmessage: Limit recursion of variants in D-Bus messages
This is the analogue of commit 7c4e6e9fbe, but applied to the
`GDBusMessage` parser, which does its own top-level parsing of the
variant format in D-Bus messages.

Previously, this code allowed arbitrary recursion of variant containers,
which could lead to a stack overflow. Now, that recursion is limited to
64 levels, as per the D-Bus specification:

https://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-marshaling-signature

This includes a new unit test.
