Merge r2166:2168 from trunk/:

Bug#32440:

Put information about the free space in a tablespace in
INFORMATION_SCHEMA.TABLES.DATA_FREE. This information was previously
available in INFORMATION_SCHEMA.TABLES.TABLE_COMMENT, but MySQL has
removed it from there recently.

The stored value is in kilobytes.

This can be considered as a permanent workaround to
http://bugs.mysql.com/32440. "Workaround" becasue that bug is about the
data missing from TABLE_COMMENT and this is actually not solved.

Merge r2160 from trunk/:

Fix Bug#18942 by dropping all foreign key constraints at the end of
DROP DATABASE. Usually, by then, there are no foreign constraints
left because all of them are dropped when the relevant tables are
dropped. This code is to ensure that any orphaned FKs are wiped too.

Bug#30919
  "Rows not deleted from innodb partitioned tables if
  --innodb_autoinc_lock_mode=0"

  Due to a previous bugfix which initializes a previously uninitialized
  variable, ha_partition::get_auto_increment() may fail to operate
  correctly when the storage engine reports that it is only reserving
  one value and one or more partitions have a different 'next-value'.
  Currently, only affects Innodb's new-style auto-increment code which
  reserves larger blocks of values and has less inter-thread contention.

ha_innodb.cc:
Bug30919
  Only set *first_value if it is less than autoinc value. This allows
  a higher value to be hinted when operating as a partitioned table.

"Database crash due to ha_innodb.cc:3896: ulint convert_search_mode_to_innobase":

When unknown find_flag is encountered in convert_search_mode_to_innobase()
do not call assert(0); instead queue a MySQL error using my_error() and
return the error code PAGE_CUR_UNSUPP. Change the functions that call
convert_search_mode_to_innobase() to handle that error code by "canceling"
execution and returning appropriate error code further upstream.

autoincrement columns can't contain negative values. With the fix, the
autoincrement table counter is set to 0 if the maximum value read from
the autoinc column index is negative.

Add test for the bug fix but the test is not really useful as the server
needs to be restarted half way through the test. It has been added for 
reference only.

Fix another compiler warning on Windows in InnoDB.

ha_innodb.cc:

Fix compiler warning: ::get_auto_increment takes a ulonglong
for nb_desired_values, but InnoDB's trx struct stores it as
a ulint (unsigned long).  Probably harmless, as a single
statement won't be asking for more than 2^32 rows.
