Description:
The global variable cfg_app_xcom_st* the_app_xcom_cfg; should be declared "extern" in 
xcom_cfg.h and then *defined* in xcom_cfg.c
This breaks the one-definition rule.

How to repeat:
Read the code, look at output from 'nm --print-size' for various compilations units group_replication.so

Suggested fix:
See description.
