An error occurred when trying to load sample plugin on stable/1804 branch:
load_one_plugin:145: /usr/lib/vpp_plugins/sample_plugin.so: undefined symbol: sample_main
load_one_plugin:146: Failed to load plugin 'sample_plugin.so'

Root cause was found that sample_main was not defined in sample.c, the fix already exists on master branch, so just merge it to stable/1804 branch.

api: Avoid the usage of the freed registration by the API calls
162b70d 
This issue happens if:
- the API client connects via Unix socket
- the client issues the *_dump API call and immediately disconnects

What happens after is that the API handler keeps sending the *_details
messages, however at some point the write fails, and the socket is
deleted.

The attempt of a use of the registration pointer results in interpreting
the socket as a shared memory socket. This results in a crash, because
the data in this structure then does not make sense, like the below:

The approach in this change is to avoid the closing operations "here and
now", but instead mark the the registration as a zombie and place
a forced RPC towards a callback that does the actual cleanup work.

Forced RPC is handled via the API processing loop with barrier sync,
so we are guaranteed not to have any API processing in-process.

leading check failure and vpp cannot start.
