Adding new fields Last_{IO,SQL}_Errno and Last_{IO,SQL}_Error to output
of SHOW SLAVE STATUS to hold errors from I/O and SQL thread respectively.
Old fields Last_Error and Last_Errno are aliases for Last_SQL_Error and
Last_SQL_Errno respectively.

Fields are added last to output of SHOW SLAVE STATUS to allow old applications
to use the same positional arguments into the row, while allowing new
application to benefit from the added information.

In addition, some new error codes are added (especially for the I/O
thread) to be able to provide sensible error message.

The problem was located to lie inside current NPTL pthread_exit() 
implementation. Race conditions in this code can lead to segmentation
fault. Hovewer, this can happen only in a race between first thread 
calling pthread_exit() and other threads. 

Workaround implemented in this patch spawns a dummy thread, which
exits immediately, during thread lib initialization. This will exclude
segment violations when further threads exit.
 


include/my_pthread.h:
  define macro NPTL_PTHREAD_EXIT_BUG which controls whether workaround
  in my_thread_global_init() is included or not.
mysys/my_thr_init.c:
  Spawn a dummy thread in my_thread_global_init() to initialize pthread 
  lib internal variables.

  Solution by having the second table added in the parser to the
  list of used tables, won't work because checking of rights of merge
  tables goes over table_list->next_local and checks the rights, so
  we will fail there.
