Fix warnings at 'make htmldocs', and formatting issues in the resulting documentation.
test.h: Fix some typos in kernel-doc parameter description.
Documentation/*.rst: Fixing formatting issues, and a duplicate label issue, since using sphinx.ext.autosectionlabel in conf.py, referes to headers are generated automatically and sphinx will not complain about identical headers among documents anymore.
The downside is, automatically generated header labels within one document now cannot be overwritten manually anymore. Thus duplicate headers within one document have to have different wording, i.e. this patch modifies some headers.
Documentation/api/*: Flipping over to a page "API" containing a single link to another page "API" seems like a formatting issue. The patch removes one level of indirection.
v2: Several documentation fixes
v3: Do not touch API documentation index
