BUG #9056 Added --routines flag to mysqldump to enable mysqldump to be able

to dump PROCEDURES and FUNCTIONS.


client/mysqldump.c:
  BUG #9056, added dumping of functions/procs to mysqldump
  - added opt_routines (--routines/-R)
  - added dump_routines_for_db, function that dumps proc and funcs
  - added calling of dump_routines to dump_all_tables_in_db and dump_selected_tables
mysql-test/r/mysqldump.result:
  BUG #9056 new test results for mysqldump --routines
