Revert multiple meaningless eclass documentation changes, notably adding a lot of placeholders and documenting implementation details. These changes were aimed at silencing (valid) documentation warnings without actually providing valuable documentation to the end users. While some of these changes were beneficial, it would take a lot of effort to review them all and the author is unwilling to fix his mistakes. Signed-off-by: Michał Górny <mgorny@gentoo.org>
