kernel-doc/docproc prep work for reStructuredText

Jon, I was hoping we could consider nudging things forward a bit in the kernel-doc and docproc reStructuredText front already in 4.7. I know it's a bit close to the merge window, but this should not interfere with anything else, and some of it are just trivial cleanups that I've been carrying around locally.

Obviously this doesn't actually add anything that uses them yet, but I think it would be helpful to have some common base in to ease collaboration.

BR,
Jani.

Jani Nikula (8):
kernel-doc: rewrite usage description, remove duplicated comments
kernel-doc: use rst C domain directives and references for types
docproc: add variables for subcommand and filename
docproc: reduce unnecessary indentation
docproc: abstract docproc directive detection
docproc: abstract terminating lines at first space
docproc: add support for reStructuredText format via --rst option
docproc: print a comment about autogeneration for rst output

Jonathan Corbet (1):
kernel-doc: produce RestructuredText output
