Fixes during review of new pushed code

Change bool in C code to my_bool
Added to mysqltest --enable_parsning and --disable_parsing to avoid to have to comment parts of tests
Added comparison of LEX_STRING's and use this to compare file types for view and trigger files.


client/client_priv.h:
  Added OPT_TRIGGERS (to get rid of compiler warning)
client/mysql.cc:
  Added cast to get rid of compiler warning
client/mysqldump.c:
  Added OPT_TRIGGERS (to get rid of compiler warning)
  Abort if we can't write to outfile (even if --ignore-errors is given)
client/mysqltest.c:
  Added --enable_parsning and --disable_parsing to avoid to have to comment parts of tests
include/my_sys.h:
  Make my_progname const
include/my_time.h:
  Avoid using 'bool' in C programs
mysql-test/lib/init_db.sql:
  Align with mysql_create_system_tables
  (Ideally this file should be auto-generated from the above script)
mysql-test/r/mysqltest.result:
  Test for --enable_parsing
mysql-test/r/variables.result:
  Update results after fix for overflow checking of max_heap_table_size
mysql-test/t/information_schema.test:
  USe --enable/disable parsing instead of comments
mysql-test/t/mysqltest.test:
  Test for --enable_parsing
mysql-test/t/sp.test:
  USe --enable/disable parsing instead of comments
mysql-test/t/variables.test:
  Portability fix for 64 bit systems
mysql-test/t/view.test:
  USe --enable/disable parsing instead of comments
mysys/my_init.c:
  May my_progname const
mysys/my_static.c:
  May my_progname const
mysys/thr_lock.c:
  Remove not needed casts
sql-common/my_time.c:
  Change bool -> my_bool as bool is not portable in C programs
sql/field.cc:
  Test number_to_datetime() for -1 instead of < 0 (Safety fix)
  New prototype for TIME_to_timestamp()
sql/item.h:
  Don't have prototypes for both uint32 and ulong as these 'may' be the same thing
sql/item_timefunc.cc:
  New prototype for TIME_to_timestamp()
sql/log.cc:
  Remove compiler warnings
sql/mysql_priv.h:
  New prototype for TIME_to_timestamp()
  Added function for comparing LEX_STRING
sql/set_var.cc:
  Added overflow checking when setting ulong variable
sql/sql_base.cc:
  Added function is_equal()
  Changed strncmp -> is_equal() as strncmp() to not match "V" (instead of "VIEW")
sql/sql_class.cc:
  Added comment
sql/sql_select.cc:
  Portability fixes
  After review fixes
sql/sql_trigger.cc:
  Use 'tables_alias_charset' for comparing database name
  Use 'is_equal()' to compare file type. (Old code didn't do the comparison correctly)
sql/sql_view.cc:
  Use 'is_equal()' to compare file type. (Old code didn't do the comparison correctly)
sql/time.cc:
  New prototype for TIME_to_timestamp() to allow easyer mapping to C function
sql/tztime.cc:
  bool -> my_bool (to allow calling C code from C++ code)
sql/tztime.h:
  bool -> my_bool (to allow calling C code from C++ code)
