Subject: [PATCH v4 01/11] scripts: kernel-doc: Add the basic POD sections

The NAME section provides the doc title, while SYNOPSIS contains
the basic syntax and usage description, which will be printed
in the help document and in the error output produced on wrong script
usage.

The rationale is to give users simple and succinct enlightment,
at the same time structuring the script internally for the maintainers.

In the synopsis, Rst-only options are grouped around rst, and the rest is
arranged as in the OPTIONS subsections (yet to be translated into POD,
check at the end of the series).

The third of the basic sections, DESCRIPTION, is added separately.
