Fix ddns provider

[geraldhansen]

Maintainer: none
Compile tested: x86 openwrt-19.07.5
Run tested: VirtualBox

Description:

• Change parameter for myonlineportal
  As the default uclient-fetch doesn't support authentication header
  and the ddns provider myonlineportal.net support also username and
  passwort as url parameter this can be changed.
• Remove not working ddns provider
  I checked the hostname for existing DNS A and AAAA entries and these
  ones didn't have an entry.

This PR currently included in addition to your 2 commits also quite 15 unrelated commits.
You should likely rebase fix-ddns-provider branch on top on the master branch

Rebased to openwrt/packages:master

change PKG_RELEASE to $(AUTORELEASE) . See #14537

[geraldhansen]

change PKG_RELEASE to $(AUTORELEASE) . See #14537

is this something I have to do?

[neheb]

Scratch that. Just bump the PKG_RELEASE variable. Autorelease is not appropriate here.

[geraldhansen]

I removed the PKG_RELEASE variable from the Makefile

[feckert]

Sorry but @neheb meant to increase it by one, and not to remove the number.

- PKG_RELEASE:=5
+ PKG_RELEASE:=6

You could also change this to

- PKG_RELEASE:=5
+ PKG_RELEASE:=$(AUTORELEASE) 

Then the buildsystem takes care of it and we don't have to count up the number all the time.

However, I would prefer the first method first, which now has a smaller impact, because the second method is quit new.

[geraldhansen]

Ok, I got it and changed it.

[feckert]

Sorry but the Pullrequest needs another rebase to current master

[geraldhansen]

Rebase done

[feckert]

I don't use these providers, so I can't say if the change works and if we can remove the others.
Opensource is based on trust, so thank you.
Merged.

[geraldhansen]

Thanks, I tested them of course and also the one I removed.
If anyone complains, blame me and I will re-add them.
