Fixes bugs:
Bug#28837  MyISAM storage engine error (134) doing delete with self-join
Bug#31277  myisamchk --unpack corrupts table
Bug#4692   DISABLE/ENABLE KEYS waste a space
Bug#31305  myisam tables crash when they are near capacity


BitKeeper/etc/ignore:
  added unittest/tmp/*
mysql-test/r/maria.result:
  Moved missing tests from myisam.test to maria.test
mysql-test/t/maria.test:
  Moved missing tests from myisam.test to maria.test
storage/maria/ha_maria.cc:
  Merge of changes in MyISAM since December 16 -> April 1
  Fixes bug in self join (Bug#28837: MyISAM storage engine error (134) doing delete with self-join)
storage/maria/ha_maria.h:
  Merge of changes in MyISAM since December 16 -> April 1
storage/maria/ma_blockrec.c:
  Merge of changes in MyISAM since December 16 -> April 1
  Fixes bug in self join (Bug#28837: MyISAM storage engine error (134) doing delete with self-join)
  The problem is that we may be using a cached key page with old information. Versioning will fix this
storage/maria/ma_check.c:
  Merge of changes in MyISAM since December 16 -> April 1
  This fixes a problem with pack_reclength not beeing big enough (Bug #31277 myisamchk --unpack corrupts table)
  BUG#4692 - DISABLE/ENABLE KEYS waste a space
storage/maria/ma_delete.c:
  Indentation fixes
storage/maria/ma_dynrec.c:
  Merge of changes in MyISAM since December 16 -> April 1
  Fixes Bug#31305 myisam tables crash when they are near capacity.
  (This uses a simpler fix than in MyISAM by remembering the length of the current row)

  Merge of all changes from myisam/ft_boolean_search.c (This file had not been kept up to date)

@return status

@note
Once allocated, index blocks remain part of the key file forever.
When indexes are disabled, no block is freed. When enabling indexes,
no block is freed either. The new indexes are create from new
blocks. (Bug #4692)
Before recreating formerly disabled indexes, the unused blocks
must be freed. There are two options to do this:
- Follow the tree of disabled indexes, add all blocks to the
deleted blocks chain. Would require a lot of random I/O.
- Drop all blocks by clearing all index root pointers and all
delete chain pointers and resetting key_file_length to the end
of the index file header. This requires to recreate all indexes,
even those that may still be intact.
The second method is probably faster in most cases.
When disabling indexes, MySQL disables either all indexes or all
non-unique indexes. When MySQL [re-]enables disabled indexes
(T_CREATE_MISSING_KEYS), then we either have "lost" blocks in the
index file, or there are no non-unique indexes. In the latter case,
maria_repair*() would not be called as there would be no disabled
indexes.
If there would be more unique indexes than disabled (non-unique)
indexes, we could do the first method. But this is not implemented
yet. By now we drop and recreate all indexes when repair is called.
However, there is an exception. Sometimes MySQL disables non-unique
indexes when the table is empty (e.g. when copying a table in
mysql_alter_table()). When enabling the non-unique indexes, they
are still empty. So there is no index block that can be lost. This
optimization is implemented in this function.
Note that in normal repair (T_CREATE_MISSING_KEYS not set) we
recreate all enabled indexes unconditonally. We do not change the
key_map. Otherwise we invert the key map temporarily (outside of
this function) and recreate the then "seemingly" enabled indexes.
When we cannot use the optimization, and drop all indexes, we
pretend that all indexes were disabled. By the inversion, we will
then recrate all indexes.
