Removed MARIA_BASE min_row_length (duplicate of min_block_length)

Cleanup of recent code changes in dbug and my_thr_init
Added name for each safe_mutex (for better DBUG and error reporting)
Fixed that sort_info.max_records is calculated correctly. This fixed a bug in maria_chk
Removed duplicate printing of mutex address in dbug log


dbug/dbug.c:
  Cleanup of recent code changes
include/my_pthread.h:
  Added name for each safe_mutex (for better DBUG and error reporting)
mysys/my_thr_init.c:
  Cleanup of recent code changes
mysys/thr_mutex.c:
  Added name for each safe_mutex (for better DBUG and error reporting)
mysys/wqueue.c:
  Removed some mutex printing (as it's done now when we take mutex)
storage/maria/Makefile.am:
  Fixed that 'make tags' works with xemacs
storage/maria/ma_blockrec.c:
  base.min_row_length -> base.min_block_length
  (As they where basicly the same variable)
storage/maria/ma_check.c:
  Moved more common stuff to initialize_variables_for_repair
  Fixed that sort_info.max_records is calculated correctly. This fixed a bug in maria_chk
storage/maria/ma_create.c:
  More comments
  Fixed that min_pack_length is calculated more correctly
  Removed duplicate variable base.min_row_length
storage/maria/ma_loghandler.c:
  Removed duplicate printing of mutex address
storage/maria/ma_open.c:
  Removed base.min_row_length
storage/maria/ma_packrec.c:
  Removed not anymore needed code
  (One should not change any .base variables as this will affect repair with unpack)
storage/maria/maria_def.h:
  Removed base.min_row_length
