[Nut-upsdev] Prolink UPS NUT driver

[Jim Klimov]

Hello all,

  I really hope somebody picks up this bounty :)

  Going forward, however, nutdrv_qx driver should be evolved via new
subdrivers (and used) rather than older Qx drivers like blazer.

@Alexander : did you have a chance to test those devices with current NUT
master branch from Github (some time last year, preferably after 2.8.0
release in April)?

  If tests were done earlier with packaged NUT version, I suppose it would
be 2.7.4 or older. If they used whatever CentOS 6 packaged, it could be
even more antique (2.6.5?). As a community, we can only support and patch
current NUT codebase, not directly old releases, but it is mostly evolution
so what worked years before should not be worse now :)

  I *guess* current NUT might just build on CentOS 6, but CI farm regularly
only tests CentOS 7 as an example old platform (and recently Solaris 8
buildability was revived), so there may be some chizeling needed or not for
builds there.
