Update appup files of inets and mnesia according to issue #147
Fix library application appup files

As discussed in issue #147 *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.
Introduce appup test utility

This adds a test function similar to the app file test function
existing in test_server. The code is mostly taken from the asn1,
snmp and inets test suites. Low-level upgrade instruction checking
is stripped. Library application's appup files get specialized
treatment, since their content is almost static.
Add test suites performing app and appup file checks

This adds the mentioned test suites for *all* library applications.
