doc: changed section for man pages from 1x to 1

As pointed by Douglas Torrance, nowadays no application is using anymore
the 1x section for the man pages, so this patch is changing the section for
all our concerned man pages to 1 (general commands).

Took opportunity to add some missing references in "see also" sections.
