Fix edoc usage errors

Errors discovered using `erldocs`:

  'Multiple @spec tag': appended a @clear tag after macro condition;
  '@spec arity does not match': added missing argument.
Fix library application appup files

As discussed in issue #240 *all* OTP library applications use the '.*'
wildcard as up and down version. This makes library applications
always up- and downgradeable. Using the wildcard version obsoletes
all maintenance tasks regarding library applications' appup files.
Additionally, it prevents upgrade problems caused by automatically
included application dependencies when using reltool to create
releases. Missing copyright headers are now consistently present.
