If mysqld is linked against system installed zlib (which is likely compiled w/o
LFS) and archive table exceedes 2G, mysqld will likely be terminated with SIGXFSZ.

Prior to actual write perform a check if there is space in data file. This fixes
abnormal process termination with SIGXFSZ.

No test case for this bugfix.


sql/ha_archive.cc:
  Prior to actual write perform a check if there is space in data file. This fixes
  abnormal process termination with SIGXFSZ.
sql/ha_archive.h:
  Added approximate archive data file size to archive share.

Only MyISAM tables locked with LOCK TABLES ... WRITE were affected.

A query that is optimized with index_merge doesn't reflect rows
inserted within LOCK TABLES.

MyISAM doesn't flush a state within LOCK TABLES. index_merge
optimization creates a copy of the handler, which thus gets
outdated MyISAM state.

New handler->clone() method is introduced to fix this problem.
For non-MyISAM storage engines it allocates a handler and opens
it with ha_open(). For MyISAM it additionally copies MyISAM state
pointer to cloned handler.

Fixed confusing warning.

Quoting INSERT section of the manual:
----
Inserting NULL into a column that has been declared NOT NULL. For
multiple-row INSERT statements or INSERT INTO ... SELECT statements, the
column is set to the implicit default value for the column data type. This
is 0 for numeric types, the empty string ('') for string types, and the
"zero" value for date and time types. INSERT INTO ... SELECT statements are
handled the same way as multiple-row inserts because the server does not
examine the result set from the SELECT to see whether it returns a single
row. (For a single-row INSERT, no warning occurs when NULL is inserted into
a NOT NULL column. Instead, the statement fails with an error.)
----
This is also true for LOAD DATA INFILE. For INSERT user can specify
DEFAULT keyword as a value to set column default. There is no similiar
feature available for LOAD DATA INFILE.

Fixed a possible problem with reading of dynamic records
when a write cache is active. The cache must be flushed
whenever a part of the file in the write cache is to be 
read.

Added a read optimization to _mi_read_dynamic_record().

No test case. This was a hypothetical but existing problem.

  Bug#20719 - Reading dynamic records with write buffer could fail
  
  Fixed a possible problem with reading of dynamic records
  when a write cache is active. The cache must be flushed
  whenever a part of the file in the write cache is to be 
  read. This must be done before the read of the header
  and before the read of the rest block.
  
  Renamed the 'flag' and 'skipp_deleted_blocks' variables.
  
  Added a read optimization to _mi_read_dynamic_record()
  that was present in _mi_read_rnd_dynamic_record() already.
  After _mi_get_block_info() we have some bytes of the record
  in the header buffer already. No need to read them again.

  "insert into... select * from..", delete

  New test that verifies that one can insert to rows using

sql/ha_federated.cc:
  "BUG #18764: Delete conditions causing inconsistencies in Federated tables"
  
  Removed the logic in ha_federated::write_row which checked the query id of 
  each field and compared it to the thread query id.
  
  Each field has a query id, and the problem used to be that if I did an insert
  no fields specified, the field value would contain the last inserted value 
  for that field. The way to work around this was to see if the query id for 
  that field was the same as the current query id or of the rest of the field 
  query ids. If it wasn't, that told me the query didn't have the field value 
  specified.
  
  Somewhere from when I wrote that code to now the problem went away, and there
  was no longer the need for this logic. 
  
  Also removed the bool "has_fields", which needs not exist and using 
  table->s->fields is sufficient.

  The Federated storage engine used Field methods that had arbitrary limits on
  the amount of data they could process, which caused problems with data
  over that limit (4K). By removing those Field methods and just using
  features of the String class, we can avoid this problem.
