mptcpd will not work with ELL > 0.33 due to removed plugin API

[ossama-othman]

Describe the bug
The pending ELL 0.34 release removes the l_plugin API meaning mptcpd's plugin framework will need to need to find an alternative.

To Reproduce
Steps to reproduce the behavior:

1. Build mptcpd against ELL > 0.33.

Expected behavior
Mptcpd should compile clean against ELL > 0.33, and the mptcpd plugin test should succeed.

@ossama-othman , would it be possible to build/run mptcpd without any plugin? that would speed-up the specfile review. Now it's blocked beacuse koji builds for rawhide are done against libell-0.35. Thanks!

@dcaratti I just created a mptcpd 0.5.1 minor release that contains the back-ported plugin framework changes from the upcoming 0.6 release that allow mptcpd to be built against versions of ELL > 0.33.

Note that 0.5.1 only contains the ELL > 0.33 support, and does not contain the changes that support the upstream Linux kernel netlink path management API found in the upcoming 0.6 release.

thanks @ossama-othman , I confirm that it builds successfully !
