Don't do signal() on windows (Causes instability problems)

Safer, a bit faster filesort.
Code changes to avoid calls to current_thd() (faster code).
Removed all compiler warnings from readline.


BitKeeper/etc/ignore:
  Add my_global.h back.

sql-bench/server-cfg.sh:
  Added use of truncate table
sql-bench/test-insert.sh:
  Added use of truncate table
  Changed some tests to use keys instead of 'range'
sql-bench/test-wisconsin.sh:
  Cleanup
sql/field.cc:
  Add 'thd' to send() (To avoid usage of 'current_thd')
sql/field.h:
  Add 'thd' to send() (To avoid usage of 'current_thd')
sql/filesort.cc:
  Safer memory allocation;  Don't allocate pointer to buffers directly, but use an IO_CACHE instead.
  This will allow us to use more memory for keys and will also work better if the number of rows that is to be sorted is much larger than expected.
sql/item.cc:
  Add 'thd' to send() (To avoid usage of 'current_thd')
sql/item.h:
  Add 'thd' to send() (To avoid usage of 'current_thd')
sql/item_func.h:
  Cleanup

  Use mem_root instead of sql_alloc() to get more speed
