"Server Variables for Plugins"
  Implement support for plugins to declare server variables.
  Demonstrate functionality by removing InnoDB specific code from sql/*
  New feature for HASH - HASH_UNIQUE flag
  New feature for DYNAMIC_ARRAY - initializer accepts preallocated ptr.
  Completed support for plugin reference counting.


include/hash.h:
  New flag for HASH
    HASH_UNIQUE
include/my_getopt.h:
  New data types for options: ENUM and SET.
  Use typelib to enumerate possible values.
  New flag variable:
    my_getopt_skip_unknown
include/my_sys.h:
  change to DYNAMIC_ARRAY init functions to support pre-allocated buffers
include/mysql.h:
  relocate inclusion of typelib due to longlong requirement
include/mysql/plugin.h:
  wl2936
    New declarations for plugin server variable support.
    New functions for use by plugins
include/mysys_err.h:
  new my_getopt return value: EXIT_ARGUMENT_INVALID
include/typelib.h:
  new typelib function: find_typeset(), returns an int which is a SET of
  the elements in the typelib
mysql-test/r/im_utils.result:
  change to more specific command line settings
  --skip-innodb => --skip-plugin-innodb
  etc.
mysql-test/r/log_tables.result:
  set default storage engine to MEMORY so that test will succeed even
  when some of the other named storage engines are not present
mysql-test/r/ndb_dd_basic.result:
  change in error message
mysql-test/r/partition_innodb.result:
  change in results
mysql-test/r/ps_1general.result:
  bdb doesn't exist, use myisam for a non-transactional engine
mysql-test/r/variables.result:
  information schema doesn't sort row results for server variables.
mysql-test/t/log_tables.test:
  set default storage engine to MEMORY so that test will succeed even
  when some of the other named storage engines are not present
mysql-test/t/ndb_dd_basic.test:
  ALTER LOGFILE GROUP no longer silently fail here
mysql-test/t/partition_innodb.test:
  ALTER TABLE no longer silently fails for unknown storage engine
mysql-test/t/ps_1general.test:
  remove unneccessary parts
  use myisam as it is an always present non-transactional engine
mysql-test/t/variables.test:
  information schema doesn't sort row results for server variables.
mysql-test/t/warnings_engine_disabled-master.opt:
  use the new style command line option
mysys/array.c:
  change to DYNAMIC_ARRAY init functions to support pre-allocated buffers
mysys/hash.c:
