[eldap, inets]: fix testcases when ssl not is present

Add support for IPv6 connections

Currently, eldap assumes that only IPv4 will be used. This change
enables callers to use IPv6 by including the [inet6] option in the
eldap:open/2 options list. This adds inet6 to the gen_tcp or ssl
connect.  For backward compatibility, [inet] is the default if inet6 is
omitted.

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.
Deprecate asn1 functions

Those asn1 functions are no longer needed because they all have
better alternatives.
Add test suites performing app and appup file checks

Add the mentioned test suites for *all* library and touched
non-library applications.

Introduce runtime_dependencies in .app files

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.

All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.
