Fix warnings at 'make htmldocs', and formatting issues in the resulting documentation.

- test.h: Fix annotation in kernel-doc parameter description.

- Documentation/*.rst: Fixing formatting issues, and a duplicate label issue due to usage of sphinx.ext.autosectionlabel and identical labels within one document (sphinx warning)

NB: checkpatch.pl will complain about flow control statements (i.e. usage of "return") within the macro kunit_test_suites(suites_list...).

v2: Several documentation fixes

v3: Do not touch API documentation index

v4: Replace macro argument in test.h by named variadic argument
