Previously, linking a field of e.g. a calc record to itself
(calc.INPA = calc.A) directly or through a chain of other records
that support to follow the link for attributes like units, precision
caused an infinite recursion and crashed the ioc.
Affected records: calc, calcout, seq, sub and aSub
Also added support for seq link 0 fields which had been added meanwhile.

In some cases the license-identification header was missing,
so I added that as well. Replaced the remaining headers that
specifically identified "Versions 3.13.7 and higher".
Makefiles and the build system were deliberately excluded.
