Peter Maydell 152d1967f6 kernel-doc: Use c:struct for Sphinx 3.0 and later
The kernel-doc Sphinx plugin and associated script currently emit
'c:type' directives for "struct foo" documentation.

Sphinx 3.0 warns about this:
  /home/petmay01/linaro/qemu-from-laptop/qemu/docs/../include/exec/memory.h:3: WARNING: Type must be either just a name or a typedef-like declaration.
  If just a name:
    Error in declarator or parameters
    Invalid C declaration: Expected identifier in nested name, got keyword: struct [error at 6]
      struct MemoryListener
      ------^
  If typedef-like declaration:
    Error in declarator or parameters
    Invalid C declaration: Expected identifier in nested name. [error at 21]
      struct MemoryListener
      ---------------------^

because it wants us to use the new-in-3.0 'c:struct' instead.

Plumb the Sphinx version through to the kernel-doc script
and use it to select 'c:struct' for newer versions than 3.0.
