libopkg: cleanup inside the public header files

No functional changes!
Just a cleanup like whitespaces, blank lines, tabs and reformating lines
longer 76 characters.
Also adding the missed comments at the closing bracket from the #ifndef
HEADER_FOO_H ... #endif loop. This helps to identify the associated
preprocessor elements like theay already exits in some files.
