HEAP: Copies the key count to a backup variable and sets the key count to zero.
That way, no HEAP function will ever try to touch any index.
Re-enabling is done by copying back the backup variable.
To avoid memory leak at table close, disable deletes all index trees.
Re-enabling must be done with empty indexes and data anyway. Otherwise,
the indexes would need to be repaired, wich HEAP is not capable of.
MyISAM: Only the key_map is cleared and set.
Re-enabling must be done with empty indexes and data. Otherwise, repair needs
to be done which will enable all keys persistently.
The former implementation disabled only non-unique keys and maked this persistent.
The new implementation additionally can disable all keys, but only without
making this persistent. Re-enabling all keys can be done without repair,
if data file and indexes are empty.
heap/heapdef.h:
WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again).
Pulled hp_clear_keys() out of hp_clear().

Added the new functions for disabling and enabling keys and to ask for the key state.
include/heap.h:
WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again).
Added a new HP_SHARE element to save the key count while keys are disabled.
Added declarations for the new functions.

WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again).
Extended disable_indexes() for all keys and no save.
The argument is now 'mode' as it must handle different cases.
Extended enable_indexes() for no save.
The new feature needs the new argument 'mode' with the same semantics as in disable_indexes().
Added indexes_are_disabled() to ask for the key state.
Extended the existing call to enable_indexes() by the new argument.
sql/ha_myisam.h:
WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again).
Modified the declarations of dis-/enable_indexes() for the new argument.
Added the declaration of the new function to ask for the key state.
