  Changed paths:
    M src/lib-stats/stats.c

  Log Message:
  -----------
  lib-stats: Allow unregistering + re-registering stats.

Fixes:
Panic: stats_register() called after stats_alloc_size() was already called - this will break existing allocations

This could have happened with doveadm HTTP API when using multiple commands
in same HTTP connection.
