Added testing of pthread_key_delete (to fix compile problem on SCO) (Bug #2461)

DROP DATABASE now assumes RAID directories are in hex. (Bug #2627)
Don't increment 'select_full_range' and similar statistics for EXPLAIN queries. (Bug #2506)
Test in configure if pthread_key_delete() exists (to fix compile problem on SCO) (Bug #2461)


BUILD/compile-pentium-max:
  Added --with-raid
configure.in:
  Added testing of pthread_key_delete (to fix compile problem on SCO)  (Bug #2461)
include/my_pthread.h:
  Added testing of pthread_key_delete (to fix compile problem on SCO)  (Bug #2461)
innobase/include/data0data.ic:
  Added missing newline
mysql-test/r/raid.result:
  Test of DROP DATABASE with RAID directories in hex
mysql-test/t/raid.test:
  Test of DROP DATABASE with RAID directories in hex
sql/sql_db.cc:
  DROP DATABASE could not drop databases with RAID tables that had
  more than 9 RAID_CHUNKS because DROP DATABASE assumed raid tables where in decimal while the RAID CREATE code assumed directories was in hex.(Bug #2627)
sql/sql_select.cc:
  Don't increment 'select_full_range' and similar statistics for EXPLAIN queries. (Bug #2506)
sql/sql_udf.cc:
  mysqld crashed if mysql.func table didn't exists (Bug #2577)
