Subject: Replace ref() with reference() in inets files
This supersedes PR #1185 (submitted by @KrzysiekJ) that changed
all occurrences of ref() with reference() in inets files.
However, there is little point in having these types only in comments.
So, these types are now exposed as type declarations for the record
fields they appear. While at it, uncommented more commented out type
declarations and declared types for records defined in the affected
modules and header files.
Some type-unfriendly and obsolete code related to supporting code
ungrades with a really old OTP release was also removed.
