For every call to mi_lock_database(F_[RD|WR|EXTRA_]LCK) - add
current thread to the list of threads accessing this table.
For every call to mi_lock_database(F_UNLCK) - remove current
thread from the list of threads accessing this table.
storage/myisam/mi_test1.c:
All standalone programs must define their version of _mi_report_crashed()
by including mi_extrafunc.h.

(list of threads accessing a table).
Whenever table is marked as crashed, call mi_report_crashed() macro
to provide useful information.
