This showed to be problematic in case of name clashes with external scripts or in case of abrupt test termination (hanging netns' weren't easily reconducible to ovpn). Rename common helper entry points and all shared globals in the ovpn selftests to ovpn_ or OVPN_ names so test scripts and wrappers use a single explicit prefix. Also rename the temporary network namespaces created by the tests from peerN to ovpn_peerN. This makes leaked namespaces easier to identify. This is a mechanical refactor only, behavior is unchanged.

[NOTE: it depends on libmedtls for decoding base64-encoded keys] ovpn-cli implements the netlink and RTNL APIs and can thus be integrated in any script for more automated testing. Along with the tool, a bunch of scripts are provided that perform basic functionality tests by means of network namespaces. These scripts take part to the kselftest automation. The output of the scripts, which will appear in the kselftest reports, is a list of steps performed by the scripts plus some output coming from the execution of `ping`, `iperf` and `ovpn-cli` itself. In general it is useful only in case of failure, in order to understand which step has failed and why. Please note: since peer sockets are tied to the userspace process that created them (i.e. exiting the process will result in closing the socket), every run of ovpn-cli that created one will go to background and enter pause(), waiting for the signal which will allow it to terminate. Termination is accomplished at the end of each script by issuing a killall command.
