bsc_fd: Add a build option to be able to debug fd list corruption
bsc_register_fd on an already registered fd can corrupt the list
in a heavy way and make the select end in an infinite loop, this
code will workaround the issue and provide a way to set a breakpoint
at the right position in the code.
