fixing for platforms, where pthread_t is not numeric (as for musl, where it is a pointer,

POSIX sadly did away with the requirement that pthread_t must be a numeric):
- printing thread ids as pointers with '%p' instead of converting them to unsigned int and
  printing them with '%u'
- using separate 'avail' and 'thread' arrays in pools to record status of pooled database
  connections
