InnoDB: Replace for loops with memset() where possible.
innobase/btr/btr0cur.c:
Replace for loop with memset()
innobase/buf/buf0buf.c:
buf_print(): Remove for loop for initializing counts[].
Similar to index_ids[], the elements of this array will
be initialized when they are allocated, i.e., counts[n_found++] = 1.
innobase/os/os0file.c:
Replace for loop with memset()
innobase/page/page0page.c:
Replace for loop with memset()
innobase/trx/trx0rec.c:
Replace for loop with memset()
