MINOR: cli/activity: add 3 general purpose counters in development mode

Browse Source 
The unused fd_del and fd_skip were being abused during debugging sessions
as general purpose event counters. With their removal, let's officially
have dedicated counters for such use cases. These counters are called
"ctr0".."ctr2" and are listed at the end when DEBUG_DEV is set.
