[LTP] [PATCH] network/lib6/getaddrinfo01: rewrite with the new API + use static hostnames
Alexey Kodanev

Mon May 17 10:56:36 CEST 2021
The test is now independent of various machine settings
regarding the test host name as it adds predefined names
and aliases to /etc/hosts file and restores it to its
original state after completing the test.
This should fix the following failures:
* when gethostname() returns an alias name that doesn't
match canonical name;
* No AAAA record for the returned name from gethostname().
Addresses and names added to /etc/hosts are more or less
unique, so that there are no conflicts with the existing
configuration.
Also most of the duplicate code is now gone.
